LENOVO U31 U41 and LENOVO ThinkPad T450 T550 detail

For Chinese District, Mr Lanci said at present China area share has to 35-37%, the future there is still room for growth but is not very big, mainly focus on the requirements China region to achieve better profitability level, also can continue to make product more refined, better, put to use high user experience, make products the light is a lot of people to buy, but also to establish a leading position in the market. In addition, Mr Lanci said acquisition of the IBM x86 server, enterprise products do up. In China, Lenovo can put the enterprise products do the relational customers to. This is the association at present in the commercial sector and enterprise field strategy.

Development of David Roman will be the Lenovo brand is divided into three stages, first of all, Lenovo is a China based company, its development in China is very powerful, and incredibly, the first stage should belong to China's development stage; the second stage we can say that after the acquisition of IBM's personal computer division to in 2009 2008, this stage, adjustment stage, belongs to. How to adjust at this stage, how to adapt to the internationalization of the change and the pace of internationalization. In 2008, experienced a very difficult period, with the change of the market environment and the outbreak of the financial crisis, this time the association also in constant adjustment, constantly adapt to the market trend of the rhythm of the game; the third stage is a high growth great period for lenovo. From 2009 until now, the market share from the original global sixth has been developed to become the global leader, to become the world's first, in the high growth period, Lenovo has become a trul
y global company, has truly become a global leader in computer.

Lenovo U41 body with 4cells LENOVO U41 Battery B surface paint surface before into a matte surface, C surface from black to gray, in general, the overall color of U41 is more uniform, the subjective feeling is more simple. Lenovo U41 screen at the still quite satisfactory, using the common 16:9 ratio of 14 inch LED backlit screen, the maximum resolution of 1366 x 768. There is a 720P camera is arranged above the screen, can achieve good video call function.

From the product application, at present the Lenovo PC business SMB, consumer and business three business groups, in the commercial sector is mainly sell ThinkPad products, has been around for a very long time to remain in such a position of a market leading, including both at home and abroad. In the consumer market, Lenovo has reached the first in the world, but also to achieve a profit growth, while in the SMB field, our product line and its products, and products of ThinkPad, Lenovo coverage in the low-end, ThinkPad is in the high-end positioning, in the SMB field, Mr Lanci said Lenovo the main objective is to enhance the market share. In addition to Chinese outside, at present share has not reached such as big business and consumer market share position, so the next goal is to focus on the increase in SMB sector of the market share, especially in areas outside the China.

LENOVO M40-35 with 32wh LENOVO M40-35 Battery is a big screen entertainment in the LENOVO upcoming, during an appearance on the M40-35 extension of the concentric design LENOVO classic, cover full texture, simple yet stylish. At the same time, it also uses the AMD flagship FX-7600P APU with AMD R5 M230, independent graphics card can easily achieve dual graphics card crossfire, machine has more excellent performance in terms of performance. In addition as a video of this, the machine is also equipped with LENOVO SonicMaster bel master technology, can provide more comfortable audio-visual, game experience. Below we have a look at the specific performance of the M40-35.

David Roman think of a company, the process of an excellent brand building, it must first be a brand, and became a brand which can be based on this success, after a very successful and powerful brand, it can have a foothold in this market.

David Roman said, Lenovo CEO Yang Yuanqing decided long ago, Lenovo is not only to gain market share, but also in the brand's success, it is going to be a great brand globalization. A great company and a great brand is different, if you want to become a great company, you need to have a strong supply chain, strong shipments data, you need to have very good financial data. As a great brand, you in addition to have these, you also need to have a and user, there is a good relation between and your customers, have a good interaction. You need to let all consumers will think you are a great brand, this is a great company and great brand is not the same place, Lenovo is undoubtedly towards a great brand forward.

And to achieve this goal depends mainly on the following points, the first is the association in three years ago began to consolidate the market foundation. If we look at the distribution of European countries, it should be said is very fragmented, there is no one like China and America of a country, a channel forming can cover a large market. So the main management mode is to take root to each country, every country has its own national local sales and management team, continue to build the local channel relationship, guarantee it has a strong operation system in each country, are successful in all of the product line to guarantee it. Secondly, it should be said that from the initial acquisition, the business field from Lenovo, IBM based view is strong, the past three years the consumption of products, including PC products, including flat so also do together, we have implemented in all countries, a situation in all channels and all market segments are full the blossom.

Lenovo U31 with LENOVO U31 Battery adopts the type of shaft sinking is very common screen design, the maximum opening angle of about 130 degrees. Lenovo U41 the overall style is the most popular style of simplicity, dressed in white, the appearance of a lot of extra points for this machine. Especially for the fashion Master and MM, having a greater temptation. Because of cost considerations, ABS engineering plastic body is adopted, it has little effect on hand.

Cloud Gate test model is designed according to the basic notebook computer and household personal computer, suitable for DirectX device 10 compatibility, efficiency score is 21208 points, the efficiency ranking just below a high order PC game, and the performance scores are also not much difference.

As a new product of TOSHIBA L50-B series with TOSHIBA PA5185U-1BRS Battery of games electric pen of the third generation, Satellite L50-B continuation of many Satellite L50-B series laptop design style fuselage configuration, thickness and weight also is almost the same as that to maintain the design style consistent perhaps for consumers, is not easy to forget about the laptop products impression, but also of course will let the advantages and disadvantages of original products continue. The first Satellite L50-B excellent thickness and weight design for portability, it is really a bonus points, this is the recent for high performance common game pen electric fuselage structure design, but as a game notebook, aiming at the design of the actual game experience is also inadequate, such as the keyboard can provide a set of hotkeys etc., are to enhance user convenience in using the laptop. But the electric pen, see LENOVO placed a connection management software, with the previous Smart software such as Manager, for considerable attention to game player network efficiency, is helpfu

In the left side of the fuselage, ThinkPad T450 is equipped with a One Link interface (port replicator interface), USB 2 interface, Headset / charge off microphone combo interface, and the card reader interface. Can meet the daily needs of the business. This evaluation of the ThinkPad T450, with the Intel core i7-4510U processor, 8GB of memory, 6cells LENOVO ThinkPad T450 Battery, large capacity 512GB solid state drive, GT 840M graphics card. With the Intel core i7-4510U, is a Haswell architecture based on the fourth generation of Core i7 low voltage processor, using the 22nm process, with 4MB level three cache, clocked at 2.0GHz, turbo boost after can ascend to 3.1GHz, uses four threads design of dual core, the largest TDP 15W, is a low voltage processor an energy saving type.

Compared with the fuselage silver appearance, body B, C on both sides of the species used carbon black design, including screen frame for scrub treatment, and in imitation of metal wire drawing design for the body surface C, the overall feel better.

At the bottom of the fuselage design of Satellite L50-B is relatively simple, and has 4 large pads, edge part of left and right sides in the fuselage front-end respectively have a speaker, stereo sound can be realized easily. It also can be seen, Satellite L50-B uses 4cells TOSHIBA PA5184U-1BRS Battery, so you can more easily achieve thin fuselage design.

Mixed mode graphics professionals is one of the 14 "features, although the technology is not very new, but the application is rare in the workstation level. Dynamic switching of AMD graphics technology is AMD's first seamless handover solution, similar in function to the NVIDA Optimus, seamless switching between integrated graphics and the graphics card, graphics card switch can automatically select the application configuration file. To open, closed when not needed, can prolong the life time of the battery. This is particularly suitable for mobile group, usually placed in the office can rely on high performance ThinkPad 14 as a desktop machine, and mobile use, switch to more power saving mode, you can have it all. This part will be introduced in the test section.

The speaker part ThinkPad T550 with 56wh LENOVO ThinkPad T550 Battery relatively good results, but also do not have too high expectations, because no matter how high-end laptop speakers whose sound is like that. Although sound in general, but it is still very comfortable keyboard, the keyboard has a large key process and high resilience, typing on the keyboard allows users to enjoy the pleasure of.

LENOVO ThinkPad Yoga 15 and LENOVO ThinkPad X250 T450s L450 review

ThinkPad always give people are business notebook computer image rules, professional, and in recent years it is also through the new design and new ideas, to convey some different ideas, fashion and modern into the old commercial this. Different from the traditional classic T, X series, S series ThinkPad, from its inception to positioning in the more fashionable young business people, it will ThinkPad the connotation remain and continue in appearance, also changed the black traditional style, adding a lot of innovative thinking.

We use the CINEBENCH R10 performance of the processor are tested, the single nuclear score is 6013 points, binuclear score is 11062 points, the overall performance is very good, deal with all kinds of mainstream applications are currently can provide excellent operation performance. NVIDIA GeForce GT 840M 28nm Maxwell GM108 chip based on GT, is the successor to the 740M. With 384 stream processors and 8 ROP units, 1029MHz core frequency, support dynamic acceleration to 1124MHz frequency, memory interface 64bit and 2GB DDR3 vram.

On the last night, ThinkPad released a new series of commercial this product -- ThinkPad Yoga 15 with 8cells LENOVO ThinkPad Yoga 15 Battery, not only show the side of S series of elegant fashion, but also will flip design Yoga series of fusion. We get our hands on the ThinkPad Yoga 15 is currently the top with series products, with the Intel core i7-4510U processor, 8GB of memory, large capacity 512GB solid state drive, GT 840M graphics card. The 15 inch screen, the resolution to 1920 * 1080, and support for touch operation. In addition to hardware performance mainstream, 360 degree flip screen into Yoga design concept, but also one of the highlights, this new product next, we have a look at this product what kind of performance.

The specific models of the evaluation of the ASUS X552LA: VM590Z7600, the specific configuration: AMD FX-7600P processor, 4GB memory, 1TB hard disk, 2GB memory of the mechanical AMD R5 M230 graphics card, touch screen 15.6 inches 1366 x 768 resolution, the machine pre installed Windows 8.1 operating system.

X552LA with 4cells ASUS X552LA Battery cover adopts concentric design classic ASUS, with ASUS "ASUS" logo, in the middle of the only style of simplicity, black top raises the overall style. In addition, the circular cover covering the surface texture also is generous enough to let the whole feel more comfortable. In addition, the top cover rich texture also makes the body not easily sell, also not easy to stick leave fingerprints.

ThinkPad X250 is listed after X240, the difference is less than two months time. Basically X250 is introduced as the popularity of the X250s version of the machine, the hardware configuration and the latter is almost the same, while the screen is weaker than that of the latter, X250 and not X250s Full HD or IPS.

With the "practical" to describe the X250 of the business of the business is not too much, the stability and security, design some time as frivolous at present is not suitable for the course of business, the future will be more and more thin notebook. In short, X250 with 6cells LENOVO ThinkPad X250 Battery is definitely ThinkPad style relatively strong product, perhaps it than before the change is very big, but it can not shake its position in the field of business.

The hardware configuration, the Intel core i5-4210U dual core processor the ASUS four thread X552LA super book is equipped with the 22nm process, integrated Intel HD4400 graphics standard 64GB SSD core, solid state disk +500GB mechanical hard disk combination and single 4GB DDR3 1600MHz high speed memory, can sufficient strong.

This link, we tested by the software of PCMark 8, a total score of the test was 1788, the overall performance can be daily entertainment and office use.

This session, we were tested by PC Mark8 software, to maintain the WiFi network connection during the test, the screen brightness to 50%, the software will simulate video browsing, Webpage browsing the daily operation. After testing, the software gives the life time of 1 hours 50 minutes, after all, the machine equipped with only a piece of 44Wh lithium battery, so the overall endurance performance relative to the general.

In the heat the test link, the stability of the system testing tools we use the software of AIDA 64 were tested in the testing process, continuous full load in processor, memory, hard disk, and after 30 minutes after thermal imaging analysis. In the cooling effect, the body heat of C mainly concentrated in the cooling air outlet and a touch control board area, the highest temperature in the cooling air outlet, is only 37.1 degrees; mainly concentrated in the corresponding region in the D cooling fan body surface heat, most of the temperature is 45.7 degrees, other regional heat well, overall thermal performance is excellent.

This evaluation of the ASUS X552LA with ASUS X552LAV Battery standard 64GB SSD solid state drive. In order to facilitate testing of its performance, we choose AS SSD Benchmark this specifically for the SSD test software designed. You can test out continue reading of solid state disk write performance, including small 4KB file transmission performance and so on, show the performance can be divided into two kinds, one kind is the MB/s form, the other is a IOPS form.

The machine shell with a matte matte process, with "little red" ThinkPad LOGO is this a series of identification. ThinkPad series of changes in the larger local than the keyboard, ThinkPad L450 is using a new chocolate keyboard, but "Little Red Riding Hood" is still in the.

ThinkPad T450s with LENOVO ThinkPad T450s Battery still used a fog screen, the anti reflective ability makes the enterprise users can also take time for in the face of light discomfort office environment. The rotating shaft can also study the ThinkPad L450's "heart", metal hinge shaft characteristics, not only can make the screen opening and angle reaches 180 degrees, looks more rugged, durable.

How to distinguish good and bad heat dissipation performance, the highest temperature can not represent what. Ventilation vent temperature is the highest, if not, it is only that the heat dissipation problem. When most of the heat accumulation in the cooling vents near the location, and other parts of the temperature not higher than 40 DEG C, it can determine the cooling system design belongs to a more reasonable.

ASUS X552LDV 15 inch 16:9 HD fog screen surface effectively reduce the light reflection, provide better visual enjoyment for users. Just below the screen is Lenovo logo a. ASUS X552LDV with ASUS X552LDV Battery body C surface still has many bright spots. What first attracted the author is concerned with logo clusters located in the lower right corner of the frame of C. The new logo red, blue Intel logo and new logo product characteristic.

It is worth mentioning that, ThinkPad L450 can also be customized as needed, customers can not only in the Intel vPro Technology (Intel vPro), to select the port locking, trusted platform module, and other types of enterprises, can also purchase LOGO, the most important is to provide 14 different product combination Lenovo, provides give customers a variety of options.

Alienware 15 and LENOVO Yoga 3 14 review

As the ASUS ROG G series of a member under eSports laptop, GL771JM does with many e-sports ROG elements in the fuselage design, of course, the most eye-catching is the black body, relatively bright red color, as a brand representative color, make the product itself identification also increased a lot. But the fuselage structure design of GL771JM, but not as the traditional ROG G series laptop was full of ambition, but with a family N laptop series mellow and soft feeling, with the ROG G series, the whole body structure and design and G56 series electric pen, there are different approaches but equally satisfactory results of the wonderful design. In fact, a careful comparison of the two paragraph of the aircraft, and more can be found even in I/O terminal configuration is quite similar, but GL771JM RGB terminal into mini DisplayPort, adds support for three display screen output function. As for the G56 series advantage pen electricity, from from the sound technology N series laptop, collocation Headset / micro
phone independent audio jack, and subwoofer random bonus, in the overall sound will experience more better than GL771JM.

If less on pen friends electric sound presentation, GL771JM in the overall hardware specification configuration, than the G56 series of high order several more prominent, whether in the processor or independent display chip, has greatly promoted the efficiency, perhaps you can think of GL771 as the G56 series of hardware Enhanced Edition, may be easier to understand the laptop. But in the hardware configuration, the GL771JM with 6cell ASUS GL771J Battery or the existence of a few areas in need of improvement, in the portion of memory, the biggest support capacity if can go to 32GB, for the love of high hardware specifications of the game player, perhaps even more add a few minutes of attractive, after all, the fuselage bottom cover provides convenient replacement and upgrading. Moreover is the storage disk configuration, 7200 turn 1TB HDD configuration, you really don't know where to start it, if only to cost considerations, may wish to consider hybrid should disk configuration, for there will be some help performance, of course, if you re
ally like this pen electricity, reluctantly replaced it SSD solid state drive, is an efficiency way to upgrade.

Notebook computer is usually used for mobile office, both in people's work life, play a very important role. Since the super this appears, more to meet the needs of the mobile office business people, get of consumer love. Recently, ASUS brings ASUS X550LNV series of gold, silver, minimalist coat with 14 inch thin body, we can see that the ASUS computer has been in the production of computer technology, has been upgraded to a new level.

Ice Storm Extreme test mode, then get efficiency scores showed 85131 points.

GPU-Z can be seen in the Intel HD 4600 display chip information, FPU clock 400MHz. It also can be seen in NVIDIA GeForce GTX 860M independent display chip, with 4GB GDDR5 independent memory, GPU clock is 1020 MHz.

This Asus GL771J with 56wh ASUS GL771JM Battery uses is FX-7600P processor AMD of Kaveri architecture, with DDR3 4GB memory and 1TB mechanical hard disk, the independent video card graphics for the APU built-in R7-Graphics with R5-M230 hybrid crossfire. The FX-7600P processor codenamed "Bald Eagle" translated as "vulture" (how many a little bit 90's TV drama, the villain of the taste), it uses the socket FP3 slot, built-in Kaveri architecture of four physical cores and 8 graphics core, thermal design power 35W, the maximum frequency of 3.6Ghz.

The ASUS X552W is a very high value products, the machine core i7-4558U processor, the Intel Haswell platform, equipped with fourth generation intelligent Intel core seamless fusion sharp torch graphics card, 4GB DDR3 memory, 500GB hard disk and 8GB hybrid mechanical SSD. There has been a great improvement in the product performance, and low power design and make new outstanding performance in the aspects of life.

Strong inner need more corresponding packing to foil, light using designed ASUS X552W with 4cell ASUS X552W Battery appearance fashion, a total of berries, vanilla, cocoa brown color optional white. Then let the feelings of this product excellences and everybody.

This part, through our online play online video to test, test process to keep the screen brightness to 50%, connect to the network through the WiFi, and close the Alien FX lamp. Before testing for 100% of electricity consumption, the remaining power 30 minutes after playing for 86%, estimated 13 Alienware in non game mode using the high load condition, the whole life can reach 3.5-4 hours, than other alien games this is not a small upgrade.

Alienware 15 with 8cells Alienware 15 Battery the top of the screen has a 2000000 pixel camera, with a shaped body indicator light, convenient for checking the running state. In addition, the machine is also equipped with a stereo pair of digital microphone can effectively filter the noise, in the voice and video call can bring better entry effect.

ASUS GL551J GL551JK GL551JM and ASUS PU451LD PU550CA review

ASUS in the recently launched a new PU550C game notebook, body appearance of architecture design of previous generation PU550, body shape and almost no change in the situation, the new PU550C is built on the hardware, intensive, with the Intel fourth generation of Core i7 series processors, 16GB memory, 2 128GB SSD RAID 0 1TB HDD schema match hard disk configuration, the most important is the PU550C from the previous NVIDIA GeForce GTX 765M independent display chip, direct upgrade to the current electric pen drawing chip the highest order GTX 980M independent display chip in the computer, the overall effectiveness, does have a certain growth. In addition, 15.6 inch display screen is also from the previous Full HD 1920 X 1080, the replacement for the current use of WQHD+ 2880 X 1620 real screen resolution, also have certain effect to visual experience points.

From the Pirfiform Speccy software, you can see the hardware specifications, detailed, contain Intel Core i7 2.50GHz processor, 16GB memory, NVIDIA GeForce GTX 980M graphics chip, Raid 0 architecture of 256GB SSD and 1TB HDD hard drive configuration.

Internal packaging also does not have too big difference, can avoid the vibration and impact of sponge tightly clad electric pen body, the rear is equipped with a special transformer box. Special transformer for the separation cable configuration, the volume of the transformer seems a little small than before. By the transformer old Delta Electronics manufacturing, to provide international standard 100-240V~2.34A/50-60Hz voltage configuration, the output voltage is 19.5V/9.23A. But in the weight of the transformer, special transformer ASUS PU550C power- ASUS PU550C Battery cable with weight about 818g, compared with PU550CA 586g, weight 232g, about a HTC M8 with the last of the protection shell weight, but for there will be substantial influence not convenience, the truth will not be too big.

With the electric pen body protection bagged up, in the first picked up the feelings, in fact, with the previous generation models gaps. With the built-in lithium battery weight is about 2.51Kg, the weight of the body, more of a 1TB 2.5 inch hard disk PU550C, PU550CA more than the weight of about 242g, of course, also include other hardware configuration of different.

Rechargeable lithium battery for the design of detachable, installation mode and the same general electric pen. Rechargeable lithium battery for 6Cells / 56Wh ASUS GL551J Battery set. Rechargeable lithium battery weight is about 312g, the design is also not too heavy. Come back see fuselage design, fog surface texture coating while creating good visual texture, but still easily stained fingerprint oil need often to wipe, can keep clean. With metal hair texture in the light screen cover can see detailed texture, with metal ASUS Logo and ROG Logo with respiratory lamp design. Pen electric fuselage black ROG identification of red body lines, which is almost equal to represent the design of ASUS ROG.

PU550C uses the dark body color gray, unlike A all black color, basically the two colors have the same visual experience, in actual use, shallow gray if leave fingerprints oil, than black more obvious to some, so diligent cleaning becomes a very important thing.

The material of metal ASUS brand Logo is inlaid on the screen cover, and unlike the eSports laptop has design breathing light gorgeous (mean as a sub brand of AORUS have no such design...). In the front of the fuselage of the visual sense of view, PU550C does have the main thin capital. The front end of actual measurement fuselage not containing rubber anti-skid pad thickness is 20.95mm, compared to the previous PU550CA with 6cells ASUS PU550CA Battery 21.21mm not a big difference.

A dedicated input voltage transformer as the standard international supply voltage, output voltage 19V / 6.32A configuration. The actual measurement of special transformers and power cable weight of about 524g, with the eSports laptop isn't design is too heavy, but also enhance the convenience for carrying

ASUS has for its ROG gaming brand launched many new products, including the fuselage shape quite distinctive eSports computer host G20, and a positioning in the high ranks of eSports laptop GL551 series. Small make up the secondary test this ASUS ROG GL551 series gaming laptop with 6cell ASUS GL551JK Battery, equipped with 15.6 inch screen, the DVD composite CD-ROM GL551JM, in body weight and thickness comparable with previously tested ASUS and ROG G56JR, as ROG GX500 series laptop before seeing more thin. Built in Intel fourth generation of Core i7 series processors, 16GB memory, NVIDIA GeForce GTX, the largest independent 860M display higher order level hardware drawing chip with the highest 256GB SSD hard drives and other configuration hardware specifications, the overall point of view, many game player can really meet the needs for efficiency.

.But in the thickness of the body like this, the laptop is still provided removable hardware architecture, the original factory default is DVD composite burning CD-ROM, the user can also change into 2.5 inch hard disk, providing more diverse product expansion. The front end of the cover can also be seen on the screen slightly protruding device architecture, is used to make the screen cover to open more convenient. Almost as high a fuselage structure, match body edge design of circular arc, little eSports laptop despot, but more of a calm technology texture. The body right has DisplayPort image output terminal, two groups of USB 3 port (a group of support charging function). The rear and HDMI terminal, VGA computer output terminals and the power input socket.

Circular arc design edge folding angle also provides laptop overall sense of mellow. Fuselage end provides double cooling hole configuration, basically the current commercially available game electric pen or the eSports pen electricity, all with double heat radiation hole configuration, in order to increase the heat dissipation of the whole. Fuselage end not containing rubber anti-skid pad thickness is 21.48mm, and the 21.16mm fuselage end thickness ASUS PU451L with 5200mAh ASUS PU451L Battery, in fact, no big gap. The left side of the fuselage with anti-theft lock, RJ-45 cable network terminal and the two group USB 2 port. Finally, you can see the microphone sound source socket, earphone sound source socket and SD memory card slot.

The front end of the left configuration has SD/MMC memory card slot. Two holes in central lamp configuration, used to identify the starting state and battery state. On the right side of the fuselage can see Headset / microphone composite audio plug and a USB 3 port.

The arc body waist line so that the original should be thick body look thin many, one can see on the right side of the DVD composite CD recorder. You can also see the anti-theft keyhole configuration. Fuselage end did not deploy any I/O terminal, can only see the rechargeable lithium battery slot.The fashion of the dazzling silver, cutting-edge technology exquisite, luxury blend with global wisdom science and technology with the ASUS GL551J with ASUS GL551JM Battery the Intel.

In the hardware configuration, since it is positioned in the eSports electric pen, for the needs of network connection is particularly important, after all, now there are many games will tie line function, RJ-45 cable network terminal as a fixed specification configuration, of course no problem too big, but only 2.4GHz of the wireless network specifications, let a person really there is a spring feeling. Temperature control parts of the performance, people can not help but think of long ago ASUS laptops overheating tradition, perhaps some exaggeration, although not overheating situation in the game, but if we can use the system of double cooling fan, make the overall stability and more ascension, as the battery capacity is part of, uh! Suggest you or even a special transformer together bring out more comfortable. Overall, the ASUS ROG GL551JM to meet the most hardware of high order the needs of users use, additional game experience is quite complete, with less than 45 little friends want to taste the price ba
nd, perhaps for eSports pen electricity consumers, is a good choice.

Single fan, single copper tube design using the cooling system of ASUS PU451L, the stability of the system testing tools are running AIDA 64 software processor, graphics card and other components will be full after a period of time using the thermal imager were tested in the keyboard surface, the maximum temperature of 41.5 degrees, the average temperature of 36.4 degrees, although most of the heat accumulation in the keyboard right part, but feels just a warm feeling, will not affect the use, but is located on the right hand side of the heat radiating window will bring great distress to the normal use. At the bottom of the fuselage, the maximum temperature of 46 degrees, the average temperature of 28.3 degrees, only in the radiation near the mouth of the heat distribution, performance is quite good. Puts forward Beats Special Edition 15 on the right side of the screen frame some let hand temperatures up to 40.5 degrees, without much heating assembly position temperature is so high it is difficult to satisfactory, but that the daily use almost no influence.

If the perfect standard requirements for this ASUS PU451L, it does have a groove point full, from outside to inside everywhere is not perfect, but as an entry-level notebook, setting apart on the right side of the air outlet opening, it will all weigh very well, screen, keyboard and so on are in line with the pricing, coupled with a thin body, the HP brand ASUS PU451L with 6cells 56wh 5200mAh ASUS PU451LD Battery , in my eyes, can be called the model home introduction.

ASUS P550L P550LAV PU551J PU551JA PU551JD and LENOVO N20p review

ASUS P550L weight up to 5.57 pounds (about 2.52 kg), due to the addition of the drive, its measurements are 14.8 x 9.8 x 1.1 inches. At the same time, no drive retina MacBook Pro 15 for the weight of 4.46 pounds (about 2.02 kg), measurements of 4.13 x 9.73 x 0.71 inches. The 14 inch HP mobile workstation is the three paragraph of the thinnest and lightest one, it weighs only 3.57 pounds (1.62 pounds), measurements of 13.35 x 9.33 x 0.83 inches.

This notebook as a flagship station, has been able to solve all the problems in the work. If your company's business does not need around requires large computational graphics business expansion, then choose cheap, function weaker notebook may be more sensible choice.

The great thing about P550L with 44wh ASUS P550L Battery is that the 3K resolution screen this gorgeous, in 15.6 inch notebook is equipped with 2800 x 1620 pixel screen previously rare. More importantly, this screen color reduction is very accurate, the user can carry out more detailed adjustment in the built-in Color function in Calibrator.

The previously mentioned HP is more expensive option, its price as high as $3087 (about 18950 yuan). Although the price is higher, but the performance of ZBook 14 than P550L: it is the highest support only 1080P screen, the processor also uses frequency is the only 2.1GHz Intel core i7-4600U AMD FirePro graphics are a little weak. However, Zbook memory of up to 16GB, which is two times of P550L.

The new generation of P550L with ASUS P550LA Battery competitor. This notebook is the resolution of 2880 x 1800, at $1899 (11657 yuan). It is equipped with frequency as the Core i7 2.5Ghz processor, graphics for the GeForce 750M. Although its configuration is less than P550L, but its shape is more beautiful, more frivolous, memory is two times P550L, battery life is longer, the price is more reasonable.

The ASUS series of games, is one of the many game player heart very inspiring series products. After years of development, ASUS has become the choice of big price game game player group. Today, we will be evaluated by ZOL testing center of the ASUS series of high-end notebook PU551.

ASUS PU551 uses the 6cells ASUS PU551J Battery, uses GTX880M high-end graphics, product calm atmosphere, dignified and generous, below we together look at his specific performance.

The ASUS is equipped with high-end core i7-4800MQ processor, this processor has obtained 654 points score in Cinebench test. In order to more directly feel the score, we can get the strongest game previously tested the Alienware 18 compared to 722 is the main frequency with this notebook is 2.9Ghz i7-4910MQ score. HP Zbook 14 i7-4600U in this test score was only 295.

NVIDIA Quadro K2100M graphics card also let P550L with ASUS P550LAV Battery received a score of 1710 on the 3DMark card test, while the HP Zbook 14 score only 1208 points, the latter card is AMD FirePro M4100, memory for 1GB GDDR5.

Blue mould has always been to simple founder to its own characteristics, weight and volume are relatively large, the surface edge products showed clear, cold sci-fi atmosphere. ASUS PU551 with the P157SM series mold product appearance to maintain the basic agreement.

Thick body, hale line, and stable color, ASUS PU551J series with 10.8V 56Wh 6cells ASUS PU551JA Battery brings the first visual impression of our. The design is very low-key, black type of skin coating body, feel feels metal touch not cold, but more than a few warm.

Although the ASUS PU551 is a gaming notebook, tonnage is big, we still use electronic scale on the weight of the weighing.

As you can see, P157SM die weight is relatively large, empty weight ASUS PU551 3.435KG, a travel weight is 4.445KG, for long-term mobile user is not a small burden.

Core i7 4710mq, attached to the fourth generation of core I series Haswell architecture, 2.5GHz fundamental frequency, four core eight thread, the largest single nuclear turbo 3.5GHz, Quad turbo 3.3GHz, with 6MB three level cache.

For a game originally said, cooling performance is very important. Just imagine, if the students are network game player, and because of the long-term heat pressure suddenly reduced frequency of stuttering dropped, be called pigs teammates, is very cup. Therefore, we use AIDA64 and Furmark to ASUS PU551 GPU and CPU at the same time with, to observe the temperature.

After 20 minutes of baking, LENOVO N20p with LENOVO N20p Battery kernel temperature let us slightly surprised, although the game in this high temperature accords with the psychological expectations of everyone, but GPU is more than 90, 86 degrees CPU grades are really not very ideal.

ASSD Becnchmark let us satisfactory results, although continued to read 478.64mb/s read and write 300.68mb/s speed is not very good, but 4K 24.04mb/s, the random read 55.46mb/s write performance is very high, this is a project the largest user daily operation of the association, is very beneficial to the daily experience. The solid state disk ASUS PU551 to get the score of 889 in the ASSD test, performance is very ideal, is a very good news for the user

ASUS PU551 uses the 6cell ASUS PU551JD Battery and Core i7 4710mq processor, 16GB DDR3L low voltage 128G solid-state hard disk, memory, hard disk and 1TB mechanical GTX880M high-end graphics, configuration is very powerful, also reserved a plurality of hard disk, we here for you to understand the specific performance.
