Premium games this Acer 4745G profiling

Premium games this Acer 4745G profiling.

Time to move on to March, gradually as the SNB new platform products listed, dealers are scrambling to clean up inventory notebook products last year. I'm using the next-generation processor notebook must upgrade in performance, but since the launch of product performance, overall profit is full of gimmicks and other factors, the price is also not very approachable, which also left many consumers with valued performance. For such users, in fact, in this particular point in time, choose a cheap enough price's old product would be a wise choice. ACER LAPTOP BATTERIES.

Acer 4745G as last year of best selling models still for consumer prepared has multiple match of products, today we to for members brings evaluation of this paragraph products of core parts part by cool duo i3 350M processor and HD 5,650 independent graphics by composition, although its processing performance does not is high-end, but tie this paragraph graphics still can smooth run most of 3D game, then plus the machine now price only 4 k more, can said is a paragraph has higher price/performance of notebook.

This appearance is still that we are familiar with the style of 4745G, which is one of the Acer my usage of the classic mould, its a top cover part of the use of a ripple in the film printing, looks beautiful but vulnerable to leave fingerprints. We had a plane in to actual means test, and there is no clear settlement, prove the top cover of the product can provide excellent protection for the screen. ACER laptop battery

Side b screen borders part of the 4745G class to handle piano paint effects, the camera still central location of the border is set on the screen, the border Although aesthetically pleasing, but easier to tainted fingerprints for use mirror-screen the machine may be in a strong light conditions causing inconvenience to the users.
4745G c is still using the traditional style of the Aspire, around the keyboard Panel using the same punch as a surface treatment effect, select dark grey color, has a good contrast to the keyboard regional effects, while the overall color and more harmonious. Integrated touchpad design, you can avoid foreign bodies out dust, the left and press the key to the resistance is moderate, feel better in actual practice.

Why the notebook is always hot? Exposing the notebook cooling defects

Why the notebook is always hot? Exposing the notebook cooling defects.

A long time, notebook because the strictures of the fuselage, at a time when the design has to consider the question of the heat sink. As notebook computer performance fast improve, its internal CPU, and GPU run frequency increasingly fast, corresponding by produced of heat also on increasingly large, how let notebook in small of space within, quickly to internal heat disseminated out, not only is notebook design production manufacturers must to resolved of problem, while, upgrade chip schema, improve energy efficiency and reduced chip calorific value, extended notebook life time, is Intel, and AMD, upstream chip manufacturers of task. Next, we'll take a look at portable design used in cooling technology.

Symptoms for the disease itself: the new Sandy Bridge Framework more conducive to enhance heat dissipation

Thermal comfort of a direct impact on the user's experience, second generation of Intel Core Duo Sandy Bridge architecture intelligent boost 3D gaming performance, HD encoding, decoding performance, is a further milestone for Intel. Using second generation 32nm process technology, the new structure of these second generation high-k metal gate (HKMG) technology manufacturing, advanced technology brings energy efficiency, and reduce heat.

At the same time, second generation core processor with wisdom, according to the different run types dynamically adjust the frequency of the CPU and the GPU, achieve the maximum performance or energy consumption, and join the new power balance algorithm to manage power consumption and heat dissipation and optimal performance. Due to the introduction of a new generation of power-balancing algorithms, new algorithms allow between processor core and the core video cards to have dynamic equilibrium, when detects CPU performance or operation of the system requirements for more powerful graphics performance, TDP resources will be inclined to it for the time being, to this in the heating and power consumption allowed within the scope of providing greater headroom, achieve the best balance of performance requirements and heat sink.

Processor AMD APU series: thermal lift, life advantages

In AMD, including AMD E/C in the early series of ultra low-power processor, AMD processor implemented in recent years APU a series now, using 32nm process manufacturing process and internal code for Llano, a total of three series, number of core quad-core and dual-core, power is divided into and 35W (35W suffix M,45W suffix MX), mainly for laptop and desktop markets. As a result of the new framework, so thermal advantage of lift, battery life is also very obvious.

Regardless of in moved Office, and HD audio play, and 3D game battery life test in the, APU power control and performance performance are appeared out amazing of charm, especially APU accelerated processor of low power run and double graphics switch mode, better of balance has performance and life Zhijian of balance, while in does not sacrifice strong graphics performance of situation Xia, to meet user more of moved Office and audio entertainment using demand, implementation has more long of battery life time, and brings more excellent of fever control.

Cooling solution: tube active cooling fans, keyboards, shell auxiliary cooling

Heat pipe + fan, is a portable basic heat, the biggest advantage of heat pipes fast on a chip pass heat to the heat sink, and then by fans venting heat forced. Only some of the special structure of passive (no fan) products, at present almost all notebooks have adopted this style of active cooling heat sink. And notebook cooling fan with automatic intelligent speed control, depending on the CPU and GPU temperature, or the heat sink temperature and automatically adjust the fan speed to reduce noise effect.

Because of the high calorific value of the CPU and the GPU, so designing better notebooks are usually dual heat pipes, and even three-tube design, you can more quickly on a chip pass heat to the heat sink, and then by fans venting heat forced to effectively reduce internal heat accumulation of the fuselage, improving user hand touch comfort.
By four weeks, opening at the bottom of the cooling vents on the back of the machine, through the cold and hot air flow, remove body heat. At the same time, and cooling vents thermal compatible laptops inside or with special air duct flow design, using heat sink holes and internal structure to create better air circulation, to enhance heat dissipation.

Auxiliary cooling: keyboards, shell is also a thermal window

As the keyboard area occupies most of notebook c area, and area below the keyboard is the fever's largest motherboard, laptop keyboards are in operation with varying degrees of heat. Use bottom boards can also be the keyboard to generate passive conduction of heat, or some thin and light notebook keyboard convection heat sink thermal, tapping the keyboard bounce, complete cold air inflow discharge hot air through the key hole, reached a certain level of cooling. Heat sink while the keyboard fully utilizing resource of the fuselage, but too high a temperature touch, can also affect the user comfort. So they usually left keyboard operation area (left hand) temperature is slightly lower, right (right hand) slightly higher temperatures.

Since notebook internal narrow, so also auxiliary cooling notebook engineers using the shell. In addition to the common appearance of ABS engineering plastic, metal-looking models, the use of metal stronger than plastic thermal conductivity away from, well the auxiliary cooling, because metal fuselage shell has become the largest radiator.
Manufacturer's dedicated solution: ASUS laptop icecool, HP laptop CoolSense, Toshiba laptop airflow cooling technology

Compared with conventional thermal solutions, some notebook manufacturers also developed unique thermal solution, such as ASUS icecool airflow cooling technology, HP CoolSense, Toshiba, and other heat dissipation technology, also in favour of the notebook thermal improvements, more comfortable operation.

ASUS exclusive IceCool cool cooler cooling technology/ASUS Laptop batteries.

Long time using notebook, especially keyboard operation area accumulation of heat will on user of using caused plagued, for this Asus launched of IceCool design, can reduced hot resistance, and improve thermal conductivity coefficient, and optimization radiator deployment of forms, implementation notebook heat of transfer, and dispersed, eventually may implementation notebook wrist supporting part of temperature below human standard temperature 25%, can implementation notebook work Shi, palm rest area always maintained in most suitable human contact of 25 ℃-28 ℃ Zhijian. Users can be outside the experience of most inside the cool, even long meetings and everyday computing, entertainment applications and do not have to worry about machine heat damage or degradation issues.

ASUS exclusive IceCool cool cooler cooling technology, creating cool experience for the users anytime, anywhere. This stems from an ASUS motherboard design skill more than 20 years of cooling solutions, through original design optimization and matching thermal modules, rapid heat cool, order books the easy wrist support parts of the heating temperature lower than the average human body temperature. Allow users even in the heat of the environment in the long run large applications such as 3D games, don't worry machines due to overheating due to poor running, guaranteeing complete machine stability while running, you can also allow your hands to enjoy more cool.

HP original/HP CoolSense intelligent thermal technology / HP Laptop Batteries.

HP coolsense intelligent thermal technology, optimize the design layout notebook internal heating parts, high calorific value of components such as graphics design position in the rear of the fuselage, makes the heat dissipation of more focus, away from users frequently touch on the keyboard and wrist support section. At the same time to optimize the air flow design, facilitates quick venting heat the body, but also through HP's simple Coolsense software for intelligent induction heat, set usage patterns.

Toshiba air cooling technology: application to the latest "super" Toshiba laptop batteries.

Airflow cooling technology, was Toshiba and Intel jointly develop new cooling technology, special based on the Intel Core Duo processor research and development of light-weight laptop, airflow cooling technology enables Toshiba to the latest Intel Core Duo CPU integrated into the slim fuselage, and maintaining high performance of the product.

Auxiliary cooling tools: heat sink base, cooling pad for common

Since most notebook in use after a period of time will still have the feeling of surface temperature rise, give users a disturbing sense of hot keyboard palmrest area, inside and outside temperature is too high to defuse notebook, upgrade the quality of use and extend the life of notebooks, also has a variety of portable auxiliary cooling tools on the market, such as common notebook cooling base, two kinds of notebook cooling pad. Notebook Cooling base cooling fan to increase air flow at the bottom of your notebook, so that the bottom of the notebook have been uniform heat dissipation, resulting in lower internal temperatures are effectively reducing the temperature of the laptop accessibility.

Summary: upstream, from Intel or AMD chip manufacturers and notebook manufacturers such as ASUS, HP, design or packaging of the heat dissipation technology in integration in portable products, users are also more sensitive to the actual feel of the product. In addition to the concerns of our Pacific notebook channel test articles, laptop stores feel the fever of prototype, is also a quick way to judge notebook cooling. Due to high-end notebook processor, and independent graphics of large configuration using, notebook internal fever also fast improve, in notebook using process in the, should as far as possible maintained notebook using environment of ventilation, maintained thermal mouth around open, out outlet around don't has block property, using notebook thermal base, secondary thermal; if has ability and conditions, needs itself or sent sales Hou cleanup notebook internal, and especially thermal tablets and thermal fan accumulation of dust; also has a small prompted, Small power adapter long running major heating, power adapter should be as far as possible away from the laptop and the human body, the effect is good.

New i5 core graphics Acer 4,750 notebook review

New i5 core graphics Acer 4,750 notebook review.

Since Intel released second generation of core processors have some time, mainstream notebook configurations are currently on the market has been going on for the renewal, core i5 2410M processor with good capacity and relatively low prices in the market in the new notebook has a considerable share. As second generation core processor than compared to previous generation products enhance the most obvious is its integrated graphics capability, so with the core i5 2410M processor and discrete graphics notebook products are also a few is not configured, today we bring you test this Acer 4,750 is such a product.

Since Intel released second generation of core processors have some time, mainstream notebook configurations are currently on the market has been going on for the renewal, core i5 2410M processor with good capacity and relatively low prices in the market in the new notebook has a considerable share. As second generation core processor than compared to previous generation products enhance the most obvious is its integrated graphics capability, so with the core i5 2410M processor and discrete graphics notebook products are also a few is not configured, today we bring you test this Acer 4,750 is such a product.

You can see from the diagram, this Asus A43S part using the keyboard Acer used duckweed-type design, keyboards around the Panel adopts the stamping effects, light gray on the palmrest and keyboard border section in the Visual area forming a clear contrast with the keyboard. The integrated touchpad design, you can avoid foreign bodies out dust, the left and press the moderate resistance and feel better in the actual experience.

The 4,750 provides users with 2 USB2.0 interface, 1 USB3.0 interfaces, 1 HDMI connector, 1 RJ-45 and 1 combo interface, and more than a set of audio, Mike-in-one card reader, you can meet the needs of most users for daily use. In terms of layout, because fewer interfaces, so the layout more rational, larger spacing between two separate USB interfaces will not affect users to plug two USB devices simultaneously. ACER laptop battery.

Storage Accessories section, the Acer 4750G with the 2GB match 500GB DDR3 1333 memory combinations of 5,400 rpm hard drive, 500GB storage capacity is sufficient for most users, and 2GB memory is relatively small for users using the 64bit system has the ability, we propose to add their own memory.

From WIN7 's system for rating this 4,750 's final score is 5.5, desktop graphic performance score lowest in the various subprojects, but considering that the machine is not configured for a video card, the results we expected. Processor in other child subkeys 6.9 points was the highest individual points and 6.1 gaming graphics score indicates that the machine can host some low-end 3D games. Score from memory and hard drive, its relatively low memory child also scored, we also propose to have the ability to users to consider adding a stick of RAM.

Call of duty 7 as a high demand for hardware of the game, representing the current application of large 3D gaming needs, often were also more likely to help us distinguish between a notebook gaming performance you can achieve what level. From a test video you can see above, only about 10 frames when tested in the machine, this shows that you want to use the integrated video card to run such a load higher 3D gaming is very difficult.

Battery, actual power consumption and heat test

ACER battery.

We mainly use Mobile Mark2007 software multimedia production is mainly used to simulate the daily Office and thorough examination of life. MobileMark 2007 is based on real-Notebook battery life and performance evaluation software. It supports Windows Vista/XP 64bit/32bit version (Professional/Home). It has three modes of testing: Productivity module, and DVD module and the Reader module, called Adobe AcrobatReader, respectively 7, Adobe Illustrator CS2, Adobe Photoshop CS2, Apple Quicktime 7.1, Intervideo WinDVD 8, Macromedia Flash 8、Microsoft Office 2003 Pro、Microsoft Project 2003、Winzip 10.0。 ACER LAPTOP BATTERIES.

In testing, we turn off the screensaver, hibernation, and set both the battery and the system for maximum performance mode as a basis for testing, you can see from the image above this Acer 4,750 notebook performance in tests to provide users with 399 minutes of battery life, the battery life in Mobile Office has been able to meet most people's needs. In addition, taking into account in testing the high pressure machine, and generally do not appear in the practical application of continuous high-load applications, plus user or power management measures through effective controls and other factors, so we have reason to believe that the actual battery life should be a better application performance.

Actual power consumption tests.

We also tested the actual power consumption of the product, we tested a total power consumption of this product in the three States. We use intelligent digital multimeter UNI-T UT71E as test equipment, namely determination of power but not on State of the connection (non-rechargeable), system startup is complete, within 5 minutes of no action, but does not sleep (non-rechargeable), and system startup is complete, processor load, disk at maximum throughput (non-rechargeable) lower power consumption.

In the three test conditions which 4,750 power 0.3W, and 13.8W, respectively, this test data than usual slightly below notebooks configured with discrete graphics, this shows that when a user is using the machine needed to pay for electricity costs are lower.

Heat tests.

In this session, we use a FLUKE Ti25 infrared imaging equipment on the calorific value of the product was a test, test measurement of portable c side, bottom and the heat sink temperature. In testing, we used the EVEREST software, select the System Stability Test, check all the items, 15 minutes after the test, and we measure indoor temperature, to enable readers to test the data with an intuitive understanding.

From above test figure in the can see, regardless of is notebook of keyboard surface also is end surface of temperature are has over has human of normal temperature, but due to temperature difference does not is large and fever regional area relative larger, so in using in the does not will to people a points temperature high of feeling, but will was fuselage overall comparison warm, such of performance in using in the also does not let people was special does not apply.

In the context of notebook sales there is fierce competition, the price of a product to a large extent about the user's purchase, the Acer 4,750 to ensure a solid body and other hardware, and machine performance at the same time, early have managed to keep the price at 4K, I believe this is attractive for users who attach importance to price. In respect of the overall machine hardware configurations, we recommend users to add 1 2GB memory for better overall performance.

We mentioned before which came with a core i5 2410M set explicit can have basically reached the entry-level standard of independence, and from software testing results and it is, 3D Mark Vantage test 7,761 compared to our more familiar with the previous generation GPU performance entry level alone have better performance. From the point of view of practical applications, this product in the daily Office, audio play and has a good low-end 3D gaming performance, and if the user wants to run some medium 3D games you need to sacrifice the quality of games to ensure a certain level of fluency.

Lenovo K27 laptop 12-inch portable business first test

Lenovo K27 12-inch portable business first test.


Has been in the business notebook market, Lenovo has a good reputation, its series notebook is tailored for business users business tool, but also targeted at high-end business needs Lenovo business build quality. Just recently, Intel Sandy Bridge platform in the overall distribution of the quarter, Lenovo Series line upgrade. Of which 12.5 inches, alloy shell Lenovo notebooks can be said that K27's most exquisite of a product. As Lenovo's first 12.5 inches Series products, K27 K series of inherited good blood, in the same security including fingerprint recognition, hard disk encryption and network security technology. In the current tests, we will for the first time for the actual performance of this product to a comprehensive analysis. Lenovo laptop battery.


As Lenovo's first commercial high-end 12.5-inch ultra-portable notebook, K27 has a strong safety in addition to the same time, a change in the business of this product gives the clumsy, dull feeling. New magnesium alloy mold design, making the machine with the battery weighs only 1.7KG, thinnest at only 17mm, thin fuselage to meet the needs of mobile office anytime. Meanwhile, the battery life capacity, K27 is equipped with dual lithium options for users of mobile office applications to provide long-term experience.
Lenovo K27 screen lid with black stripes rhythm process, eliminating the fingerprint, cover, palm rest part of the use of carbide. Compact at the same time ensuring its body is also more robust. Screen with a double buckle design shaft, the shaft resistance is moderate, when the screen 180 degrees turn to any angle within the range will not be shaking. The cover edges with a folding handle, which allows K27 screen especially strong, no matter how hard and then press the laptop lid, the screen will not be affected.


K27 rubber pads around the screen with the screen edge folding process can ensure maximum screen keyboard area will not be scratched, while the latter can effectively prevent the notebook in the closed state, the dust from the gap into the screen directly adsorbed . Careful friends may find, in the K27 body we have also seen a lot of the classic ThinkPad design. In addition to the edge of the folding roof design, the left side of the camera, LED keyboard light is also preserved, so that users operate more freely at night.
K27 shortcut function keys and other keyboard lights are concentrated to the top of the bar area, the middle part of the focus on the hard drive status, digital status, case status, disk status indicator, and provides the most common system Lenovo laptop restore function keys, in any case to avoid system crashes due to software hassles. The top of the keyboard design of the system to save, and hard disk protection mute button.

In addition, the keyboard also has a waterproof, the hole through the bottom of the diversion design, users need to worry about because drink was spilled on the keyboard and caused damage, improve the equipment and data security. In addition, the right palm rest fingerprint identification system, with random software fingerprint identification system can be realized through the landing, so that platform to further enhance security.

As the die size was significantly smaller than the K27 on the mainstream business, which also increases the difficulty of the interface layout design. Because you selected an external DVD burner solution, and its products provide a common interface to extend in the same time, the interface layout is reasonable, the main interfaces are designed in the fuselage, and the interface is distributed more relaxed, at the same time to connect a variety of peripherals is not prone to conflict.
K27 uses the Intel Core i7 2620M processor, the processor uses the latest 32nm process technology, the Intel in the early 2011's native dual-core processor, clocked at 2.7GHz, rely on the second generation of its Turbo Boost technology the highest frequency up to 3.4GHz. The nuclear integrated Intel (R) HD Graphics graphics default frequency of 650MHz, although the default frequency do not have much advantage at all, but the graphics card up to the maximum dynamic frequency of 1.3GHz, in response to everyday mobile office applications or more than enough .
Before the mainstream consumer notebooks have begun using Windows7 system, so K27 notebook's performance in Windows7 has an important reference. Windows7 system evaluation, the overall final score of 4.5, in addition to desktop graphics performance slightly before the other children are up 5.5 points or more evaluation, especially the processor core performance is very prominent.
PCMark Vantage 6396 points from the overall performance point of view, this association K27 with the Intel Core i7 2620M processor has become the key to higher frequency with the second generation Turbo technology so that its multimedia performance than the current set of mainstream This was a good performance. The 6000 results also show that the above tests that the majority of multimedia applications in everyday products fully meet customer needs.
As a portable business applications, product positioning, K27 in the daily execution of business applications in the most efficient user run concern. We chose the SYSmark 2007 Preview to consider the products in the e-learning, video creation, productivity and the effect of 3D modeling applications. From the overall results show that, in four common office applications in K27's performance is satisfactory, the composite score of 200 points or more. Thanks to the good mix of processor and memory, in which the efficiency of video creation and testing the most obvious advantage of children.

In the article, the first chapter we have introduced, K27 notebook is one of the characteristics of both the security and portability, users can choose to purchase products or programs to get the dual lithium longer periods of time than ever before. In the actual test, we randomly selected six core standard 14.88V/41Wh lenovo battery, and through random MobileMark 2007 battery life was tested.
In the test, we close the screensaver, sleep, and set the battery and the system are the highest performance model as a test basis, you can see from the image above this standard battery K2 269 minutes, this time to meet the basic life Most people in the office needs. Lenovo laptop battery.

With the new generation of office applications for business products, the sudden emergence of the crowd, more and more and more companies began to seek an appearance, functionality and practical application of balance, thus gradually forming a new generation of business notebook market. But both the product design or component performance are based on secure, portable and durable basis. We tested this for everyone this K27 notebook is a collection of lightweight and portable, functional and practical, security and stability in a product.
 Lenovo K27 in addition to platform upgrades, design is more sophisticated than, the same association with a proud LTT (Lenovo Trust Technology) technology, with fingerprint identification system and built-in security chip, which implements the physical, identity, operating system, network, the data of the "five-dimensional security." In terms of performance, based on the SNB's Intel Core i7 2620M, although the graphics performance has been missing, but compared to previous generation Core platform has been significantly improved. In addition, Sandy Bridge processors to improve performance, while GPU display good control of power, so it's life still maintain the current Core i Series models set was the level of life was significantly higher than the entry-level models alone.

Lighter, faster thin ThinkPad X220 laptop test

Lighter, faster thin ThinkPad X220 laptop test.

Extra long battery life, portable form factor, excellent production process, these are the attractions of the ThinkPad x series notebook. In early March, the Association in the United States released the ThinkPad a new generation of thin and light X220, of course, pick up the latest Sandy Bridge processor it is understandable that, at the same time, the series notebook and like T420, also uses a 16:9 screen ratio. Currently, the series notebooks have been listed, the author through the Beijing Sea Sky technology ThinkPad notebook franchised Office first to get a X220, following friends first offer some out of the box, and comparison with the previous-generation ThinkPad X201 tour. LENOVO LAPTOP BATTERIES.

Machine is still a solid black design, in a left corner there is a "Lenovo" sign, and the lower right corner is the "ThinkPad" Logo, red point is so sexy, eye-catching.


X220 remove clips from frontend design, notebook can be opened with one hand slightly. And card reader interface is set on the right side of the fuselage, rather than the X201 in front of the fuselage.

Watch machine behind port, portable form factor that not two feet is get to the desktop because X220 distribution on the six-cell battery will have some highlights.
Distribution in the left side of the fuselage with USB 2 interface, VGA interface, DisplayPort interface, USB 2.0/e-SATA dual-use interface, wireless switches and ExpressCard slot.
While the right side of the fuselage were spread to other electronic devices charging yellow USB 2 interface, card reader devices, interfaces, composite audio interface and RJ45 network cable security lock hole.

Comparison of X220 and X201 a surface and interface.
ThinkPad X220 in surface design as being more than a X201, in the lower left corner by adding a "Lenovo" Logo, and the top indicator location right by some, and removed the power supply led, changes are not particularly large.

From the above comparison chart you can see, although the ThinkPad X220 battery more prominent, but a ThinkPad X201 also is to be thin on the thickness of 3 mm. And in interface aspects, X220 phase more Yu X201 can be described as is changes huge, its will power interface set in has fuselage Hou end, will reader interface set in has fuselage right, and is not X201 Shi of fuselage left and front-end; will USB interface set in has fuselage left, yellow may charging USB interface set in has fuselage right, and is not X201 Shi of fuselage right and left, that is X220 will this two interface of set for has reversed; will RJ45 interface set in has fuselage right, Rather than X201 the left side of the fuselage; X220 has dropped gradually eliminated RJ11 interface, DisplayPort video interface is added, and two audio output, microphone input interface combined to composite audio interface.

ThinkPad X220 although the airframe smaller, but the extension interface is complete, usable,. And compared to the X201, the layout more rational, simple, easy to user actions.

ThinkPad high-end business notebook sufficient for users to consider, Esc, Delete, Back Space etc are often used buttons, design into other keys twice times the size makes it easy for users to enter operation, to avoid misoperation. As a lightweight compact high-end business, X220 is naturally no exception.

Touchpad to integrated design, and next to the trackpad design a higher safety factor of fingerprint readers, for business people, this is the system more secure encryption method.

Classic designs-ThinkPad-red pointing stick, something essential in a ThinkPad notebook. However, the ThinkPad notebooks now equipped with a flat, only the surface particle-like little Red Riding Hood, no spare, if a user wishes to other shapes, sold separately.

ThinkPad X220 and T420, the screen ratio to meet the Visual angle of 16:9, while its screen is the 12.5-inch at a resolution of 1366x768.
ThinkPad and ThinkPad X220 X201 most of the keyboard are the same, just above the keyboard function keys and keys are slightly different. X201 volume control keys, ThinkVantage button, power button only and are based on outstanding design, radian and X220 more in line with the finger, feel better-arc surface design. At the same time, Esc key, Delete key X201 with conventional design, and X220 easier to operate at twice the normal size press design.

ThinkPad X220 changed the touchpad of the integrated design, has dropped below a set of keys, this practice area larger, more convenient, more beautiful, but user is accustomed to isolation designed around key, probably it's going to be very comfortable to use. At the same time, X220 granular surface of the touchpad to feel better, better sensitivity, less prone to misuse.

X220 the camera is set in the middle of the square on the screen, rather than the X201 settings in the top-right position. At the same time, X220 removed the small camera symbol next to the camera.
X220 simplifies the led of the bottom of the screen, the case led combination on the keyboard, and charging, power, sleep, and a repeat led to get away.

Throughout the notebook side b, c, and X220 than the previous generation X201 is also made more changes. X220 design of greater emphasis on the user's habits, more human users more comfortable operating experience. At the same time, design of X220 also get rid of some red tape, such as light, it gives users a more concise, skilful, beautiful feeling. LENOVO LAPTOP BATTERIES.

At first glance, these two completely different at the bottom of the laptop, X201 to the bottom of a lot on feeling, and the X220 feel very concise, neatly at the bottom. In fact, X220 and X201 no essential differences on the design at the bottom, main hardware parts are equipped with cooling vents, speakers, docking station interface, and so on. Bottom X220 is more smooth, cooling vents and form more beautiful, more uniform distribution of speakers, so seem more comfortable.

Summary: the X220, seen from a distance you may think that this is a X201, it is hard to see what's so special about it. Through the front of the introduction and comparison between the X201 and we understand that X220 whether from contour design, the fuselage thickness, screen size, layout and other aspects of the interface, or from the key places such as design, thermal, pore size distribution, weight, have done more or less changes, user has shown more simple and beautiful styling, brought a more humane and comfortable experience. But this is just the external, internal X220 Sandy Bridge processors with the latest, more robust performance.

Business choice for this pragmatic ThinkPad L421 initial evaluation

Business choice for this pragmatic ThinkPad L421 initial evaluation.

In today's notebook products is highly competitive, ThinkPad business notebook as flagship of the brand still has many fans, and in order to satisfy the spending power of different classes of user needs, ThinkPad notebook products are divided into multiple series have their own characteristics. L Series notebook is positioned as a lower-end models in the business application, perhaps upon it you don't see the t series notebooks from the material to be used on the work of excellence, but ThinkPad's descent, excellent quality, excellent performance, and lower the price and other factors also make it a successful recruiting is a lot of users. Today we bring you reviews of this product is the ThinkPad l series notebooks launched a product L421, hope that after having read this article to let readers have a comprehensive understanding for this product.

From the configuration table, you can see, although we pointed out earlier in ThinkPad l series of positioning only low-end commercial application, but in the core parts respects the L421 should be or has a good overall performance. In contrast, the machine compared to t-series products in materials and workmanship of the fuselage had a very significant gaps, a concrete expression of this is also the cost savings, while the specific details of all aspects of the machine we will later pointed out one by one in the article.

From the material point of view this L421 addition to screen hinge, a small number of parts in vast parts of the fuselage uses ABS plastic material, using this material is brought to the high hardness and abrasive feel, but also effectively control production costs. The fuselage top cover part of the machine are made from ABS plastic, we tested a finger pressed firmly which occurs when the top cover of the sinking of a lesser degree, this shows that the top cover while it is possible to bring to the screen a role in protecting, but compared to high-end models, such as t-series, in the area of safety performance slightly smaller.

L421 configured for the user on a 16:9 14-inch matte screens, as trends and application needs change, 16:9-screen ratio is the latest generation of business product differentiation, and borders of the matte screen with matte material you can use the excellent complex light environment in order to provide users with excellent visual experience. We can see from the diagram, the machine will have two speakers on the bottom of the screen position, homeopathy is populated with more open on the bottom of the screen provides users with a Visual sense of uncoordinated.

On the surface of the keyboard layout, the L421 uses the familiar classic ThinkPad series keyboard, press on the handle, key process and the level of soft and hard part is in place, long-term use can be effective to avoid hard feelings. This machine also provides users with a common shortcut keys, and classification according to application demand be disaggregated to the left and right sides of the keyboard area, and in addition the trackpad also offers the classic ThinkPad series of little Red Riding Hood lever.

This L421 provides users with 3 USB 2 interface (the support shutdown power supply), 1 eSATA connector, 1 DP interface, 1 VGA connection, 1 RJ45 interface, 1 headphone/mic composite jacks. From a practical point of view, whether it is from there on a number of these interfaces, is adequate to meet the needs of most users for daily use in practical applications, but some of these interfaces may be due to causes and effects of xiangli too close to both.

We received this L421 sent test prototype powered by an Intel Core i5 2540M processor, this processor is based on the 32nm process manufacturing process and frequency 2.6GHz, three-level cache is 3MB, a dual-core processor and supporting HT HT, Quad-frequency acceleration technology, Turbo speed maximum frequency for 3.3GHz, the four-thread processor with dual core processing power, thermal design power TDP 35W. LENOVO Laptop Batteries.

L421 display unit using the HD 6470M discrete graphics card with this video card is AMD's second generation DX11 video card entry level products, the most important feature of the video card can support DX11 application, for the growing popularity of DX11 application, can provide a good environment for run support. This video card is based on 40nm process technology, information obtained from the current view, HD 6470M with 160 streamer, 8 texture unit, core frequency for 480-800MHz, video memory frequency is 800-900 MHz. ATI Radeon HD 6850M to be completed with 64-bit GDDR5/DDR3 memory, support DX11 UVD2 hardware decoding engine and OpenGL 4.1, integration, support PowerPlay, PowerXpress, Swithable Graphics and a series of energy-saving technologies.

L421 adopts HM65 chipset, as with previous mobile chipset based desktop chipset, HM65 H65 chipset chipset is also derived from the desktop. HM65 also uses the single-chip architecture, memory control unit (IMC) was integrated into the processor, so it is not commonly known as the MCH North bridge chips (Memory Controller Hub), there is only one platform control unit PCH (Platform Controller Hub) burden on single-chip PCI Express controller and in the past commonly known as ICH Southbridge chip (Input/Output controller Hub) provided by the function, HM65 can support up to six SATA 6Gbps interface (eSATA), 14, eight PCI-e 2.0 interface USB 2 interface, Hanksville GbE MAC Gigabit Ethernet controllers, Matrix Storage matrix storage technology, high fidelity audio, High Definition Audio Management Engine Ignition Firmware technology and so on.

This product L421 in storage systems come standard with 1 2GB DDR3 1333 memory as well as a 500GB 7,200 RPM hard drive, hard drives not only larger capacity, 7,200 RPM rotational speed can support more users to better achieve a variety of disk operations, and this class action is a more important factor affecting ordinary Office application. On the other 2GB the amount of memory, it is much too small, especially under the 64bit system will affect the overall performance of the play, so we also recommend that users who have the ability to self for the memory capacity for expansion.

From the WIN7 system of rating the L421 's final score is 5.3 in all subprojects desktop graphic performance score lowest comprehensive results and become the bottleneck, but in practice even 5.3 minutes represented by the property can also be quite well supported users turn on a variety of desktop effects. Other subprojects, processor performance and gaming graphics performance of the relatively high, judging from these two results, when the machine is applied to a different action when its overall performance should have good performance. LENOVO Laptop Batteries.

In addition to using Windows 7 's index tests, we use 3 coverage higher and users widely recognised professional performance evaluation software for this product has been tested. By 3DMARK, PCMARK and SYSMARK test effort can help us much more intuitive to learn the product at the time of application performance.

In the previous tests by testing software is very intuitive score, but for many readers, and not on the performance of these scores represent an intuitive feel. Taking into account this situation, in order to get more people on the performance of the product has a more intuitive experience, we use a number of typical it application, including the file operation, high-definition video playback, picture compression, and so on, so as to further his performance in everyday applications.

LENOVO battery test.

We mainly use Mobile Mark2007 software multimedia production is mainly used to simulate the daily Office and thorough examination of life. MobileMark 2007 is based on real-Notebook battery life and performance evaluation software. It supports Windows Vista/XP 64bit/32bit version (Professional/Home). It has three modes of testing: Productivity module, and DVD module and the Reader module, called Adobe AcrobatReader, respectively 7, Adobe Illustrator CS2, Adobe Photoshop CS2, Apple Quicktime 7.1, Intervideo WinDVD 8, Macromedia Flash 8、Microsoft Office 2003 Pro、Microsoft Project 2003、Winzip 10.0。

In testing, we turn off the screensaver, hibernation, and set both the battery and the system for maximum performance mode as a basis for testing, test this L421 notebook showing 231 minutes of battery life, nearly 4 hours of battery life to meet General requirements. In addition, taking into account in testing the high pressure machine, and generally do not appear in the practical application of continuous high-load applications, plus user or power management measures through effective controls and other factors, so we have reason to believe that the actual battery life should be a better application performance. Users who were demanding to battery life, you may want to consider replacing the larger-capacity battery. LENOVO Laptop Batteries.

Actual power consumption tests.

We also tested the actual power consumption of the product, we tested a total power consumption of this product in the three States. We use intelligent digital multimeter UNI-T UT71E as test equipment, namely determination of power but not on State of the connection (non-rechargeable), system startup is complete, within 5 minutes of no action, but does not sleep (non-rechargeable), and system startup is complete, processor load, disk at maximum throughput (non-rechargeable) lower power consumption.

In the three test conditions which L421 power 0.4W, and 25.2W, respectively, also match the performance of discrete graphics product, this means that users in the use of this laptop will result in higher overall performance, but also paying a relatively higher electricity costs.

Heat tests.

In this session, we use a FLUKE Ti25 infrared imaging equipment on the calorific value of the product was a test, test measurement of portable c side, bottom and the heat sink temperature. In testing, we used the EVEREST software, select the System Stability Test, check all the items, 15 minutes after the test, and we measure indoor temperature, to enable readers to test the data with an intuitive understanding.

You can see from the above test chart, this L421 comparison of performance well in temperature control, keyboard overall temperature close to human body temperature and the maximum temperature is only about 38 degrees Celsius, this shows that even in the case of high load operation actions that the user can still have a very comfortable feel. Thermal imaging can see in the picture from the bottom, the hard drive location has become the focus of bottom heat accumulation area, above 45 degrees Celsius as well as stating that the machine is not intended to be used was placed on the legs for a long time.

Since the product shows good performance, it is poor compared with the positioning high-end ThinkPad product where? Judging from the core allocation, although L420 mix HD 6470M a video card can bring about great entertainment properties, but for professional graphics processing with high demand users, compared to used by t-series NVIDIA NVS 4200M professional graphics as demonstrated by nature slightly superior. In addition, compared with the performance difference is even more obvious in materials and workmanship of the fuselage, plastic material shell can also provide a measure of protection, but the overall feeling of security and development are still has gaps, this machine does not provide closed clips believed would make many users feel unpleasant.

Last, although we in stressed the machine performance excellent of while also listed has its and positioning high-end of t series compared to of some insufficient, but considered to its in price aspects and t series compared to nearly 1 time times of price difference, we still had to recognized the machine in price/performance aspects of huge advantage, for no people on behalf of you pay or more focusing on price/performance of user for, this paragraph L421 does is ThinkPad series in the of a good of select.

The difference between old and new generations? Acer 4750G VS 4741G.
Acer 4750G this year released a new series, but from the appearance point of view, the 4741G looks exactly the same with the previous generation, and configuration, in addition to other processors, two products have very high similarity of the models, Similarly GT540M graphics card, the same 2G memory and 500G hard drive, then the performance of old and new generations to what kind of gap?
Although the overall appearance, the Acer 4741G and 4750G looks similar abnormal, but in some details of the design, the two models still have many differences.

It can be said Acer 4750G and 4741G in the design of the fuselage cover the same can be said.
Although the overall design on the outside of little change, but the new 4750G 4741G slightly heavier than a little, and performance improvements that life is not shortened.

The design of the keyboard surface, Acer 4750G 4741G continues the duckweed keyboard, but the design of the palm rest, 4750G-compliant material specially treated surface, covered with small protrusions, touch the plastic drawing more than 4741G comfort; and the new 4750G supports Dolby sound, in the sense of hearing better than the 4741G.
The interface layout, in addition to adding new 4750G USB3.0 outside the fuselage on both sides of a slight change in the distribution of the interface, a USB On the left side of the body moved to the right, the other big change.

In the bottom of the fuselage, the main difference between 4741 and 4750 reflected the card in the battery wear, 4741G battery dual buckle design, the user remove the battery more relaxed hand, and 4750G single-buckle design, buckle to the concave, direct hand operation is relatively laborious. ACER Laptop Batteries.

In the configuration, two products in addition to the basic processor and battery the same as outside, then the new Intel processors will bring for the 4750G what performance? The same is GT540M, in a different processor support, and will reflect what kind of game performance?

First through the WIN7 PC MARE score to score and take a look at 4741G and 4750G's overall performance.

View from the test results, except for these two configurations other than the same processor model, the second-generation Core i5-2410M were added, to enhance the overall performance of the more obvious, although the 4750G's score in WIN7 lead modest, but in a more professional machine performance testing software PC Mark VANTAGE test results, we can see 4750G in each sub-item scores were higher than 4741G many, in the total score, 4750G compared to 4741G There are nearly 24% increase, then we look at the practical application of the test results.
In daily use, we often need to file compression and decompression operations, so editors have selected a single large file with a large number of fragmented small files for testing these two notebooks, as between them highlights gap, a large file is a 3.67GB image file, fragmented files as 4985, with a total capacity of 5.00GB, then compressed using Winrar 4.00 to compress the RAR format file, then extract them, and record the compression decompression time. In the actual test, 4750G 4741G-leading file compression speed about 7 minutes.
In addition to file compression and decompression, the in everyday applications, virus scanners, image processing and other operations which we do regularly, so edit the same for both models for viruses, video transcoding and image processing test. Overall, in the format of the factory and the test light on the magic hand, Acer 4750G with a higher performance processor ahead of the 4741G, but the virus scanner when used on a little longer than the 4741.

As the 2 laptops are equipped with high-end positioning of the GT540M graphics, 3D Mark we to understand these two notebook gaming performance. Test results from the point of view, although the 4750G uses a new Core i5-2410M processor, but with the old models equipped with Intel Core i5-480M processor 4741 compared amplitude ratio performance is not a big imagination, so we took do a few tests to see the actual game.

In response to the test when the actual game, whether it is run like a "Lost Planet 2" for such a large 3D game is still the mainstream of the "Resident Evil 5" notebook in the middle of these two quality games under basically the same as the average number of frames.

25 degrees Celsius in the test environment, select the Everest software system is fully baked-in test, the test 15 minutes with UNI-T UT71E intelligent digital multimeter high-load power consumption of the products tested, and used within 30 minutes Infrared detection Wenyi inspection body surface maximum temperature of more than one location.

In the heat on, these two notebooks on the bottom part of the left leg brought 40 pairs of degrees, if using a laptop on your lap, would be more uncomfortable; Tongshi Acer 4750G keyboard surface in higher heat , compared with 4741 up to 37 degrees, 43 degrees of heat would be more heat, but when typing fingers shorter contact time with the keyboard, the user has little effect. In addition, the power consumption, higher performance, the 4750G also has a higher power, but the gap between 6 watts for the user to achieve higher performance is more deserving.

Edit Summary: Overall, although the previous generation Acer 4750G and 4741G has many similarities, however, the use of the new platform also provides users with a better performance, while also adding to USB3.0 interface 4750G superior in the expansion, and the details in the design of the fuselage, Acer 4750G also made a corresponding improvement; but in the heat and power consumption, 4750G is indeed higher than the 4741G, but with the same configuration relative to other models ratio, at the same level, but also in life in 4750G 4741G above about 1 hour, so as to buy the 4750G looks According to a very strong value. Acer laptop battery.
