Two generations of “Transformers” on the back of the design
Two generations of “Transformers,” the thickness variation is obvious, TF201 TF101′s 12.9mm to 8.3mm thinner than the more than 4mm, but the 8.6mm Samsung Galaxy Tab P7500 is not a big difference compared to the. Rivalry between children of different products, all want to take the title of this thinnest, I believe that these two products and the iPad 2 are considered synonymous with the ultimate thin and light, and then probably need to upgrade the degree of light a lot of technology to improve the cost of the , is said Toshiba’s new flat next year will reach a thickness of 7.7mm, so thin, Ge do not get the hands?

About the game to run smoothly 4Tegra 3 Top
● ASUS EeePad Tranformer Prime: Quad-Core Tegra 3 run the game smoothly
Prime’s biggest bright spot is its internal quad-core processor NVIDIA Tegra 3, then the Tegra 3 in the end is the story behind? Then I will briefly explain.
NVIDIA Tegra 3, code-named “Kal-El” (Superman), is the world’s first quad-core mobile processor. Although quad-core processor, but in fact Tegra 3 contains five core, to which four major chips made of standard silicon manufacturing processes can achieve higher frequencies, while the many tasks running dual-core solutions power more than consumption lower. Fifth cores using special low-power silicon manufacturing processes made to run at low frequency active standby mode, the task of music and even video playback, the official called “the Association” core, the English name for the Companion. “Association” core of the operating system is transparent, operating systems and applications are not aware of the existence of the core, but it can automatically take advantage of this core. This strategy eliminates a lot of software work is not necessary to write new code.
Code-named “Kal-El” quad-core mobile processor
This five CPU core ARM Cortex A9 architecture are used, they can be individually according to the workload of the startup and shutdown (described in detail later in a variety of open, close the case). Tegra 3 of this section of this automatic conversion quad-core processor is the biggest bright spot: vSMP technology, Variable Symmetric Multiprocessing, translation is a variable symmetric multiprocessing technology. Using vSMP technology Tegra 3 processor combines high performance and low power consumption. compaq presario cq60 battery
Four main core and the core of a co-
Below this picture on a Tegra 3 to show us how to use vSMP technology to achieve the five core free opening and closing, a total of sub-four cases.
Under different conditions on different core
Case 1, when the machine is in standby, audio player, video player and other simple applications, the system will only call the co-processor, clocked from 0 to 500MHz;
Of two, when the machine is a simple web browsing, simple 2D game, the system will call a standard core, other core sleep, frequency from 0 to 1.4GHz;
Scenario 3, when the machine is in Flash web browsing and multitasking and video chat, the system will call the two standard core, other core sleep, frequency from 0 to 1.3GHz;
Of four, when the machine is in full-load conditions, the core of all four standard start frequency from 0 to 1.3GHz.
As we all know, NVIDIA graphics processing skills in a high, with AMD in the desktop market in recent years has been equally matched, and in moving areas, Tegra family of integrated Geforce GPU mode has been achieved in the previous good reputation and achievements Now Tegra 3 is greater. Compared to the Tegra 2, Tegra 3 the number of GPU core upgrade from 8 to 12, the performance reached the Tegra 2 is about 3 times. In addition, Tegra 3 will also support 3D technology.
3 times in the end is what the concept? We use practical examples to show the changes brought a new GPU. Two as shown below, if the use of products equipped with Tegra 3 processor for the game entertainment, games in the water ripples, the physical effects, shadow effects are more prominent, obvious, users will live in a more realistic use of the environment.
Shadow effect is more outstanding games
The game more realistic picture
Next, we use the well-known shooter ShadowGun Prime demo clips, you can see, Tegra 3 processor for this large-scale control of the game without pressure.

5 minutes to run comparative life, summed up the back to the top
● ASUS EeePad Tranformer Prime: performance, battery life, summed up
Through the “quadrant” of this software we can also see information on processors, 4 cores, clocked from 102MHz to 1400MHz, in line with the above mentioned areas from 0 to 1.4GHz.
Hardware parameters
Although the Tablet PC to run sub-test significance is not great, because the experience of this kind of thing is not good to take data to measure. However, in view of today’s special characters, we chose to run sub to compare Tegra 3 and Tegra 2 project in a specific test score performance. We chose the “quadrant” and “security Rabbit” two software testing, specific results are as follows.
Quadrant test (Tegra 2 left to right is Tegra 3)
An Rabbit Test (Tegra 2 left to right is Tegra 3)
Quadrant test, the TF101 has been equipped with Tegra 2 points in 1998, and equipped with Tegra 3 of the TF201 was 3177 points. An Rabbit test, the results of both 5068 and 10010, respectively, the author tested a number of basic results in this vicinity.
Since carrying the Android 3.2 operating system, so the kinds of interface system which I will not go into, you need to mention the lower right is transferred out of the relevant page setup interface, Prime here have also been optimized, an increase of a key energy-saving power, a key to normal mode operation, and there will be the choice of IPS mode, including Super IPS selection and automatic adjustment options.
Bottom right of the richer set options
Super IPS screen brighter, is about 1.5 times the normal flat, brighter screens for outdoor use. Two from the following comparison chart we can see, on the left of the Prime brighter (with the most light conditions).
Prime’s left of the screen brighter
Finally, Prime’s life, the aircraft’s battery is 25Wh, keyboard base battery 22Wh. I moderate the Prime screen brightness, putting 30% of the volume, connect WiFi in cycles play a 720p video file size mp4, Prime single adhere to 8.3 hours, if coupled with extended keyboard, battery life should be able to reach 14 to 15 hours.
● PConline evaluation room summary
Asus Eee Pad Transformer Prime (32G) picture series evaluation forum quotes
Strictly speaking, not the TF101 ASUS EeePad Tranformer Prime upgraded version of the machine from the inside to the outside because of all the new look, I agree that it is a EeePad under the new tablet. Just look on the changes brought about ASUS EeePad Tranformer Prime gives different experiences on the new metal mold with thin body, the grip will be better on the comfort, while the process of drawing concentric aluminum also highlights the product’s excellence in the details. Of course, well received by users concerned about the quad-core processor is also an important selling point, as the world’s first NVIDIA Tegra 3 processor equipped with it, in addition to the hardware configuration from the leading competitors, the quad-core performance also gives users a better and smooth comfortable user experience, we can say, Prime plate off a new round of competition off.

Decision makers supply users’ needs, use needs to promote the development of production. Today’s laptops are differentiated according to user needs different trends, home entertainment this has good performance and a higher cost, in order to cater to gamers this game, fever response to the market most of the high-level configuration with the game, this is a business tends to stability, low power consumption to obtain a long life. There will expose the edge of the ultra-extreme (ie, “Ultrabook”), more lightweight body, a more long battery life, decent performance.
This often gives the impression that business is steady work, solid performance in office applications tend to not like the way the game has a high-performance graphics cards. And business people to use computers mainly word processing, photo editing and other business applications, so with a high-performance processor and stable operating environment is crucial. Of course, there are some business will be integrated into some of the fun elements, such as the article describes the Samsung 300E5A series notebook, to ensure business stability while adding a separate graphics card, significantly enhancing entertainment, office entertainment correct.
Samsung Samsung 300E into 300E4A, Samsung and Samsung 300E7A 300E5A three series, corresponding to 14 inches, 15 inch and 17 inch screen size. The article will be introduced is the 15-inch models in the Samsung 300E5A-S02, this model is equipped with Core i3, although with a low, but performance as well as most of the office to meet the daily basic needs.
This will be the appearance of the Samsung 300E5A this model, interface, performance, etc. are introduced, the first comprehensive look at the notebook’s configuration description: Samsung 300E5A equipped with Intel Core i3-2330M processor, 4G RAM, 640GB hard drive and NVIDIA Geforce GT520MX graphics card, support dual graphics switching OPTIMUS.
Why the price of gold so expensive, because it is rare and rare. For notebook computers, the cost of metal is too costly, not suitable for consumer notebook. Therefore, the majority of notebook market are based plastic material body, not only raw materials cost less than metal, the strong plasticity also makes the cost of production can be effectively controlled.
Samsung 300E5A using a 15.6-inch LED screen, the screen surface grinding process, effectively reducing the reflection. Compared to the normal glossy screen, matte anti-glare screen with advantage, for a variety of environments, especially in strong light places. For a business this is, the use of matte screen to better reflect its business value.
Samsung 300E5A more solid overall workmanship, appearance law-abiding become calm, where no special color. Cover metal materials, atmospheric tough, with plastic body, yet lightweight texture. Overall style of simple, black silver deployment pairs used for white-collar workers.
Many years ago, piano paint gradually into our line of sight, became the mainstream, but now it seems more in line with the mass of metal style aesthetic. Samsung 300E5A cover metal materials, but with a drawing effect, perhaps due to cost considerations, but the fuselage is made of engineering plastics. hp ppp012l-s Highly reflective surfaces combine to create a chic silver frame feel, drawing well-designed easy to leave fingerprints to solve a problem, but also makes the product look more grades.
Samsung 300E5A all the details in the body of work are good, rounded corners, solid and durable shaft. Screen is great, but does not seem fragile at the same time opening and closing the screen angle is also quite good, the maximum opening angle of 135 ° is sufficient to meet all occasions. Notebook lock mount design is also more reasonable position.
Today’s notebooks work more solid, more and more shape details of the design maturity. Or focus, or focus on functional design aesthetic manifestation, of course, have both aesthetic and functional design is no longer a minority. Laptop users look to attract the general public is not the primary factor in the hardware configuration, but intuitive style. So a nice, good-looking notebook with a reasonable hardware configuration, has become a trend.
Samsung 300E5A top of the screen equipped with a 30-pixel camera, the interface in more uniform distribution, this design does not appear in the actual use of cramped feeling. The machine is equipped with three USB2.0 interface, the distribution of left-right two are more mainstream, but there are some small regret, because not equipped with USB3.0 or e-SATA interface, so the number and type of the interface are quite satisfactory level.
The aircraft is equipped with two VGA and HDMI video output interface is placed in the left side of the fuselage, the basic pitch not so moderate conflict, while the right side of the fuselage smaller spacing USB2.0 interface, if the device too bulky external may interfere with each other, resulting in only one interface in an embarrassing situation.
The aircraft is equipped with a floating chocolate keyboard, the advantages and disadvantages of this design are very obvious, since these keyboard keys spaced clear, so no need to worry about misuse of the phenomenon, the dust is not easy to invade the body, adorable chocolate keyboard, arranged in neat rows , popular with some consumers love, but chocolate keyboard design nowadays covers almost all brands, very popular.
Card reader design in front of the fuselage, plug more convenient, but unfortunately not equipped with baffles, may cause dust to enter. The machine status indicator design in front of the fuselage, representing the hard drive, wireless network, charging status and power of work, the design will not interfere with normal sight here.
On the whole, Samsung 300E5A notebook interface with a reasonable, three USB2.0 interface, VGA port, HDMI port to meet the basic business, entertainment needs, although not equipped with USB3.0 interface, sorry, but for now, or USB2 .0 equipment mostly, it will not receive much practical effect.
Business Basic is the white-collar work every day sitting in the office, facing all kinds of work documents or computer screen is never silent. Office is necessary entertainment is needed. Little spare time entertainment can relieve work stress, relax, thereby improving efficiency.
Samsung 300E5A equipped with a graphics card because, taking into account the thermal performance, ultra-thin thickness can not be done, about 29 mm thinnest thickness tends to the current level of mainstream notebooks, by weighing, Samsung 300E5A single weight of 2.248 kg, Travel weight of 2.602 kg, the weight is very light, it is difficult to imagine a large 15.6-inch screen notebook weight is almost close to 14-inch models of the notebook.
In the heat of performance, we used FurMark software make this machine run at high load conditions, after an hour later, the temperature of the processor core has two stable, respectively, of 82 ℃ / 76 ℃, graphics processors temperature reached 90 ℃, heat on the average.
As inclusion of graphics card, in the heat there will be a big improvement. By thermal imaging devices for notebook surface temperature of test results, the average surface temperature of the machine keyboard 37.1 ℃, high temperature in the left part of the keyboard, the bottom is the processor and graphics card, so the performance of the hotter excusable. Although the highest temperature of the bottom up to 70.8 ℃, but the temperature is limited to vents, near the entrance to leave the heat on the temperature decreased, but the average temperature is reached 41 ℃. The Samsung 300E5A palm rest, touchpad and other parts of the good temperature performance, no signs of overheating.
Samsung 300E5A series notebook with 15.6 inch screen, the product positioning business crowd. For the business market for the product, the designer a good grasp of the design, shortcuts and other commercial properties. While ensuring business stability while adding a discrete graphics in the entertainment aspects of this impressive performance, classic styling and durable business engaging, can be described as office, entertainment, correct, is recommended.
Samsung 300E5A equipped with Intel Core i3 2330M processor, 4GB DDR3 1333MHz RAM, 640GB hard drive, NVIDIA Geforce GT520MX graphics card, Gigabit Ethernet, 802.11bgn wireless LAN and Bluetooth 3.0, preloaded with Genuine Windows 7 Home Basic (64 bit) operating system, support OPTIMUS two graphics capabilities.
Fengyun can see through the CPUID Intel Core i3 2330M dual-core processor’s basic information, the processor based on 32nm process technology, the core code-named Sandy Bridge, the default clocked at 2.2GHz, did not support Turbo Boost, shared L3 cache is 3MB, the overall TDP of 35W, supports Hyper-Threading technology with the latest SSE4.2, AVX instruction set.
Basic information about the processor, we use this software CINEBENCH R10 to assess its performance, the software is capable of single-and multi-core processor performance given visual score, Fengyun i3-2330M dual-core processors soon completion of all the test content, and ultimately get 3599 points its single-core, multicore get 7794 points, relative to the Core i5 processors, there is some discrepancy with the previous generation Core i3 2310M compared, due to slightly higher frequency, Coupled with a 64-bit systems, the performance slightly improved.

Assessment of overall performance we still use the old test software PCMark Vantage, after one full hour of testing, you can see Core i3 2330M, toshiba pa3782u-1brs 4GB DDR3 RAM, 640GB hard drive and graphics card NVIDIA Geforce GT520MX the “four core” got 5365 points total score, to meet the business, entertainment is not a problem.
Machine equipped with a NVIDIA Geforce GT520MX graphics card, graphics card NVIDIA Geforce GT520M compared to the core frequency of 1460MHz, GT520MX is as high as 1800MHz. Graphics performance by the number of cores, core frequency, memory, graphics-bit wide, pixel fill rate and other aspects of the decision. Therefore, in the same core number and card-bit wide in the case, GT520MX graphics than GT520M high frequency, along with the high performance.
It is worth mentioning that the popular Samsung 300E5A with dual graphics technology, when we need a strong performance graphics card can be used when we need long battery life when using integrated graphics. In fact SNB Core processor graphics performance has been strong, but even better graphics card NVIDIA Geforce GT520MX, hp compaq 6530b battery large-scale 3D game play would be better.
NVIDIA Geforce GT520MX discrete graphics performance, although not with high-end market positioning graphics card NVIDIA Geforce GT540MX comparable, but its good enough to cope with the current performance of the market most of the game, running, such as “Assassin’s Creed 2″ such a large There will be tons of card game phenomenon, but for the “mild players” is sufficient, such as the familiar “live football”, “Cross Fire” type of game can run smoothly at higher quality. Samsung 300E5A series notebook performed well in the entertainment.

Some time ago the company launched the ThinkPad S Series notebook personal high-end business, including 14-inch and 12.5-inch S420 S220, based on these two products do we reward Appearance, professional evaluation and a series of introduction, we have from the user point of view trial experience of the S420 did the introduction, following small series from the user point of view to talk about S220, introduced after 24 hours after the trial some of my feelings.
According to the ThinkPad naming, heard S220 I realized this is a 12-inch models, light portable is undoubtedly its main advantage, but despite this, when I first saw this laptop or is it time attracted by the compact. From the visual, compact body, thin; black color, calm atmosphere; rounded corner design, chrome frame, reveals the fashion charm.
From the touch, the first feeling is light, not to mention men, even the female compatriots who hold it all day mobile office will be very easy, there will be no inconvenience; magnesium alloy material, durable, hand press cover, very tough; scrub process, feels a bit like the skin feeling very comfortable. lenovo thinkpad x200 battery
Sorry that did not inherit the ThinkPad ThinkPad S220 and 180-degree open angle product of the classic design, in order to ensure the body of the light, so using a sinking shaft design, so that only the opening and closing angle of 135 degrees, but for the user’s use will not have much impact.
Yes, ThinkPad S220 is using the same island arc-type chocolate keyboard, percussion feel good Needless to say. The classic “red dot” remains, user more convenient. The business notebook “standard” fingerprint reader are also no less, can be more secure to protect user information. Large integrated touchpad, a larger operating area, the user is more convenient to use, but the left and right button press together more jerky, users started to use the time may be not used. sony vaio vgn-sz760 battery
ThinkPad S220 although the body is small, but the body still has most of the mainstream and practical sides of the interface, the distribution is reasonable, does not appear crowded obstacles caused by the phenomenon of connected devices, the interface position in line with most people’s habits, ThinkPad notebooks often with the Power USB interfaces among them. In addition, on the bottom of ThinkPad S220 uses the more popular one design, including built-in battery is only a hard disk in the lower right side of the warehouse left open, although beautiful, but inconvenient for users to upgrade their own hardware. It is worth mentioning that, if the user wants to remove the hard disk, you need to set the BIOS now, or if the direct split, then it is easy to damage the hard disk.
Next we look at some benchmark tests the performance of this notebook configuration. In this section we mainly use the data to speak, I will not do too much explanation, the following plug it.
Primary users like to use to test Master Lu notebook performance, because this test software simple and intuitive, here we have to measure one.
ThinkPad S220 uses i5 2467M low-power processor, integrated Intel HD Graphics Family Graphics, the overall configuration is good, powerful processor performance, but graphics performance is slightly lower, but this results in commercial products are also on the level, fully able to meet most of the office and 3D applications. asus eee pc 1015pn battery
Part 3: daily application of chapter
Through the long list of pictures in front of us, data, scores, etc., about the understanding of this notebook’s appearance and performance of the basic configuration. But having said that, buy laptop mainly to help us work and play relaxed, the data can not say what the actual problem. So, the next day we applied point of view, this notebook to see what the actual performance of them, this is the most critical.
From the top of these more common everyday office software testing point of view, this ThinkPad S220′s performance is quite good, to bring the mainstream configuration for their excellent performance and not because of its compact body and by the performance of constraints, will not lose other mainstream business notebook on the market.
ThinkPad S220 relatively smooth even though it can play 1080p HD movies, but the CPU occupancy rate reached 70%, that is, while in the movies will not even think we have other basic operation of the.
ThinkPad S220 although excellent office performance, but as an integrated Intel HD Graphics Family graphics card, so graphics performance slightly worse in high-definition video playback and 3D games to run in a bit difficult. Even the low-load operation, “Resident Evil 5″ and “Street Fighter 4″ and other games, but had reached only 20.7 and 31.56, be barely able to run it.
To be more intuitive so that we can understand ThinkPad S220′s battery life, greatly accelerates under the program in high-performance power watch movies online, 99% of electricity after 1 hour 42 minutes left after the video playback 33% of the electricity, but also play 35-minute film, also the remaining 10% of the electricity, but also to maintain the basic 16 minutes doing the whole, life should be in 2 hours and 33 minutes. This result does not look good, but please note that high-performance power solutions in small series to view video, if you lower the brightness and other properties, or browse the web, office and other simple operations, then life will be more durable to meet the Most users of mobile applications is absolutely no problem. asus a32-m50
ThinkPad S220 in appearance Edge series continues the basic design models, steady fashion, the operation feel very comfortable, while “red dot” design such as usability is also very strong, while its compact portable mobile office performance in the body more than the 14-inch S420, more in line with the needs of modern business people. The configuration performance, ThinkPad S220 and not because of the compact body and neglect the hardware configuration, its performance is definitely considered mainstream level, able to meet most of the office and everyday applications, but, because of its integrated graphics, so In the high-definition video playback and 3D games slightly difficult, but also this notebook only short board. As business people pay more attention to the life side, ThinkPad S220′s performance is also good, high-load condition in life can be up to 2 hour 33 minutes or so, the need for frequent users of mobile applications have basically enough. Overall, ThinkPad S220 in terms of design, hardware configuration, performance, office games, or in endurance capacity are relatively well-Mobile is particularly high and high-end choice for business people, although slightly worse graphics performance , but that is small business in this entertaining little weak is understandable.

The group associated with technical engineers statements to possess produced the actual planet’s lightest materials.
The actual material is actually made from small hollowed out steel pipes organized right into a micro-lattice — the criss-crossing diagonal design along with little open up areas between your pipes. toshiba pa3734u-1brs
The actual scientists state the actual materials is actually 100 occasions lighter in weight compared to Styrofoam and it has “extraordinarily higher power absorption” qualities.
Possible utilizes consist of next-generation electric batteries as well as surprise absorbers.
The study had been completed in the College associated with Ca, Irvine, HRL Laboratories and also the Ca Start associated with Technologies and it is released within the most recent release associated with Technology.
“The technique would be to fabricate the lattice associated with interconnected hollowed out pipes having a walls width 1, 000 occasions slimmer than the usual human being locks, inch stated guide writer Doctor Tobias Schaedler.
Low-density
The actual ensuing materials includes a denseness associated with 0. 9 milligrams for each cubic centimetre.
In comparison the actual denseness associated with silica aerogels — the actual planet’s lightest strong supplies — is just as little as 1. 0mg for each cubic cm.
The actual steel micro-lattices possess the advantage simply because they contain 99. 99% atmosphere as well as associated with 0. 01% solids.
The actual technical engineers state the actual material’s power derives in the purchased character associated with it’s lattice style. dell vostro 1310 battery
By comparison, additional ultralight ingredients, such as aerogels as well as steel foams, possess arbitrary mobile buildings. What this means is they’re much less rigid, powerful, power absorptive or even conductive compared to the majority of the actual recycleables that they’re made from.
Bill Peterson, supervisor associated with architected supplies from HRL, in comparison the brand new materials in order to bigger low-density buildings.
“Modern structures, exemplified through the Eiffel Structure or even the actual Gold Entrance Link tend to be extremely gentle as well as weight-efficient through advantage of the structures, inch he or she stated.
“We tend to be revolutionising light-weight supplies through getting this particular idea towards the nano as well as mini weighing scales. inch
Strong
To review the effectiveness of the actual steel micro-lattices the actual group compacted all of them till these were fifty percent because heavy.
Following getting rid of force the actual material retrieved 98% associated with it’s unique elevation as well as started again it’s unique form.
The very first time the strain check had been completed as well as repetitive the actual materials grew to become much less rigid as well as powerful, however the group states which additional compressions created hardly any distinction.
“Materials really obtain more powerful since the measurements tend to be decreased towards the nanoscale, inch stated group fellow member Lorenzo Valdevit.
“Combine this particular using the chance of tailoring the actual structures from the micro-lattice as well as you’ve got a distinctive mobile materials. inch
The actual technical engineers recommend useful utilizes for that material consist of energy padding, electric battery electrodes as well as items that require in order to lower seem, vibration as well as surprise power.

In the electricity, the common voltage, battery capacity and other concepts to measure the properties and performance of individual. Usually a single battery (including alkaline batteries) rated voltage of 1.5V, nickel-cadmium batteries and nickel-metal hydride battery is 1.2V, while the lithium-ion battery is 3.6V (some manufacturers of lithium-ion battery rated voltage calibration 3.7V) , the equivalent of three nickel-cadmium or nickel metal hydride battery voltage from the series, some of the common non-rechargeable lithium battery voltage is 3V.
Capacity refers to the size of battery storage capacity. Battery capacity of the unit is “mAh”, when the Chinese name is mA (high-capacity battery in a measure such as lead batteries, for convenience, usually with the “Ah” to represent the Chinese name is Ah, 1Ah = 1000mAh). Figure 4 The GP super battery’s rated capacity is 1300mAh, if 0.1C (C is battery capacity) is 130mA of current to the battery discharges, then the battery can last 10 hours (1300mAh/130mA = 10h); if discharge current of 1300mA, the time that power is only about 1 hour (actual work time due to the battery’s actual capacity of individual differences and there are some differences). This is the ideal state analysis, digital equipment, the actual work was not always possible when the current is constant at a value (in digital cameras, for example, because of current LCD display, flash and other components on or off and there is a greater change), so the battery can power a device is about the time value only, and this value is only through practical experience to estimate. asus eee pc 1000he battery
Since a single cell voltage and capacity are very limited, usually need several batteries battery group, to meet the needs of different equipment, the actual power. In digital cameras, the most common combination is in series battery that the battery positive and negative end to end, such as the four 1.2V, 1300mAh battery in series, to form a voltage is 4.8V, 1300mAh capacity battery pack; in the laptop, the battery is commonly used hybrid approach, that is also parallel series.

In mobile use, the laptop battery life decisions, a notebook with a lithium-ion batteries, in the non-normal temperatures, the temperature is too high or too low will bring a variety of issues, then the temperature can affect laptop battery for?
A ,0-40 ℃ is the most reasonable working environment
Notebook when in use, humidity, static electricity, temperature and so it has impact, but the lithium-ion battery is most sensitive to temperature, the temperature is too high or too low, the battery will bring negative impact to varying degrees, usually, the limits of lithium-ion battery ambient temperature -20 ℃ ~ 60 ℃, and 0 ℃ ~ 40 ℃ is the most reasonable working environment, but to play to the potential performance of laptop batteries, 20 ℃ is about the best use of the environment.
Two, -25 ℃ the following will affect the battery life
Although the laptop battery allows use in -20 ℃ environment, but this will affect the battery charge and discharge performance is very large, usually, the lower the ambient temperature, the battery activity of the active material within the lower the viscosity of the electrolyte resistance and The higher the ion diffusion more difficult, not easy to charge and discharge the battery.
For example, when the ambient temperature is below zero, the battery charge and discharge efficiency will be greatly reduced, thus charging very slow, full time after power supply is only about 60% of the original, when the ambient temperature falls below the minimum temperature limit (for example – 25 ℃), battery electrode reaction rate is very low, even from the freezing point of the electrolyte, the battery performance may be only 10%, serious impact on battery life.
Three, 60 ℃ above may explode
And low-temperature case, if the laptop battery in high temperature environment, which will affect the battery’s charge and discharge efficiency, and more serious damage to the battery, such as the use of poor quality charger or charging time is too long, making the cells larger heat, When the charging temperature exceeds the maximum limit temperature, which will destroy the battery’s chemical balance, leading to degradation of battery materials, reducing battery life.

This year, the company launched the E420s, E220s two ThinkPad Edge E-Series family of elite version of the product (E series flagship product), although they look more Classic family has undergone enormous changes, but still maintained a fine work, machine firmness and body shape is more stylish, it can be said to expand the market as its own E-Series is the elite version of the positioning performance, portability, quality, comfort, price and service requirements of a certain individual, stylish users.
And just recently, Lenovo has launched a new S-series (also part of Edge family) in the S420, S220 two products, they E420s, E220s in the same mold, but the color changed from dark green so-called friction Black card (in a different perspective, will be alternating brown and black), slightly upgraded hardware. Point of view from the campaign trail, S Series will replace the elite version of the Edge series, gradually fade into view, as a pioneer of the E420s, E220s will fade into history.

In fact, from the elite version of the E-series body, we find great hope for its association with other E-Series products, they use more expensive magnesium alloy, less weight, more body compact, the volume further reduced. Elite version of the tune some of the E series, you can also say that it is too bright, and let other so-called compatriots seem depressed. Out of the elite version of the division, which is Lenovo’s market development strategy, S Series was born, it continues the elite version of the E-series positioning.
A, ThinkPad S420: Appearance
And E420s the same mold
The evaluation of the protagonist of ThinkPad S420, it is identical with the E420s mold, aluminum-magnesium alloy body, like skin coating, texture strong chrome frame, rounded corners, unbounded Diamond screen … … everything is so familiar. The only difference is that the dark green shell into a mocha black. Lenovo’s official website through query that its “charm business’ position, breaking the ThinkPad has always been black the limitations of the S420′s aesthetic thinking to integrate technology into the classic.
After a new interior design, non-removable battery, slot-loading optical drive for ThinkPad S420′s body is more compact, at the same time, thick and full screen with a certain curvature of the fuselage to ensure solid, even so, S420 body with a thickness of almost the same coin.
The compact design allows 14-inch ThinkPad S420 on the advantages in portability, the whole weight of less than 2 kg, with a thinner body can easily be placed with packages, but also more convenient to carry around. dell vostro 1510 battery
In the ThinkPad S420 body, matte non-glare screen has disappeared, replaced by “King Kong unbounded screen”, you can even freshen up the face of it, dressed in a seamless integrated over the design so I think the end of the ThinkPad Table, and with t popular tablet.
ThinkPad S420 C glass fiber surface material, surface grinding process, with both hands placed on the palm rest more comfortable. The keyboard is still using the line 6 sub-island arc design, without any independent shortcuts, users can “Fn + F1 ~ F12″ key combination to achieve the icon corresponding to the function. Above the keyboard is a pair with a fourth-generation Dolby Home Theater audio speakers, the actual effect of the Classic with the same size compared to the more outstanding.
Trackpoint ThinkPad is an indispensable factor, S420 is no exception. The keys on the key process longer, force feedback is also quite good, and also has spill-resistant feature, the use of comfort on the keyboard, although many black fans of their disdain, but it is still the greatest degree of assurance of the ThinkPad tradition keyboard operating experience.
Family of next-generation ThinkPad touchpad all as integrated design, while ensuring the integrity of the more beautiful, but in practice when you press the left button when the mouse pointer will be more or less drift, but in the multi-touch mode of operation, the larger touchpad to facilitate the integration of many.
Order and chrome “waist” corresponds to upgrade the whole texture, ThinkPad S420 screen hinge also made chrome plated, the damping is moderate, but in the case will be open a little shake. “King Kong screen unbounded” tape around the cover to ensure that the keyboard is not offset caused by the screen imprint.
ThinkLight who also have the S420, there is no “roof” it’s built-in design needs to better ensure simple, an LED light, a reflector, plus the “unbounded King Kong Screen” and the gap between the screen, ThinkLight was born. By Fn + Spacebar to open the improved mode of operation allows the user to single-hand operation.
ThinkPad S420 provides two USB 2.0 ports (yellow USB interface can be turned off in charge of external devices), eSATA / USB 2.0 hybrid port, RJ45 network cable port, HDMI port, multi-card reader as well as compound audio jack. The left side of the fuselage USB interface, no little inconvenience, because when the right side of the USB all the time occupied would be more or less affect the operation of the mouse. Cooling air outlet on the right, through actual use, due to its upper position, and will not appear until blowing hand side of the case, users do not have to worry about.
Infrequently, such as plug interface and VGA interface cable is designed to back-end, while the eSATA / USB 2.0 interface can also act as a hybrid wired mouse or wireless mouse adapter interface, in order to liberate the right side of the fuselage 2 USB ports easy to take advantage of. In addition, SIM card slot is located in the left side of cable, with the body internal mini PCI-e slot on the 3G wireless network adapter for anytime, anywhere with wireless wide area network interconnection, because each type of configuration, the body Internally, I did not find 3G wireless network adapter, there is no reserve antenna. dell tk330
Love the black of the first ages of its superior user comfort, and secondly that it “can be frustrating nature” – the ubiquitous nature of DIY accessories and powerful. Although the ThinkPad S420 slightly less in this regard, but by the dismantling of the essence can still see the black
This mini PCI-e slot can be extended not only WWAN, you can also extend mSATA, with the association of EE 2.0 (full name ENHANCED EXPERIENCE 2.0, which is often said RapidBoot Quick Start technology) S420 System start-up time can be reduced by 30%, but mSATA is rare in the market and the price is expensive, and because of the internal space constraints, S420 only one internal mini PCI-e slot, WWAN module that mSATA and he did not have me, I did not have him.
Won the ThinkPad S420 of the C shell, you will find only one memory slot is also idle, on-board 2GB of memory? Of course not, the other a memory slot in the back of the motherboard, leaving a slot easy for users to upgrade, of course, if you need a strong memory capacity of 4GB × 2 need to S420 into pieces.
ThinkPad S420 equipped with a Intel Core i5-2430M processor, dual core four threads, 3MB of level three cache, compared with just before the 2410M frequency upgrade to the 2.40GHz, Core frequency up to 3.00GHz after the single-threaded . Just from the parameters, its deal with everyday computing tasks more onerous no problem, through the Cinebench R10 test, the higher the score also proved this point.
MAXON Cinebench by the company introduced a processor test software, which is based on MAXON’s award-winning animation software CINEMA 4D development. Cinebench by a number of tests to measure the contents of a computer processor and graphics performance, it supports up to 16 processors or processor Core tests, and can be Windows (32-bit or 64-bit) systems running.
ThinkPad S420 is equipped with AMD Radeon HD 6630M graphics card and graphics card supports hot-switching technology, 2GB of memory can handle pixel in the larger picture it is more at ease. Through the 3Dmark06 test score indicating adequate for video and audio entertainment needs.
PCMark Vantage can measure all types of PC’s overall performance. From multimedia home entertainment system to the notebook, from professional workstations to high-end gaming platform, whether in the hands of professionals, or belonging to the ordinary user, can understand the system performance through the PCMark Vantage test content can be divided into the processor test, memory test, graphics test, hard disk test.
SYSmark 2007 Preview is a software platform for a variety of PC performance testing software integrated, it actually can be used to install most of our daily fidelity simulation software to run applications (word processing pictures, video playback, 3D performance, etc.), so its Test results for the office and entertainment applications are very true and accurate, has been recognized by the industry.
Intel Core i5-2410M processor with AMD Radeon HD 6630M graphics card such a configuration will have a high fever, running 1 hour PCmark Vantage, the two images by looking up and down, the body thin ThinkPad S420 fairly good performance .
ThinkPad S420 is equipped with a 49Wh internal battery, through MobileMark2007 test, its five hours of battery life with the current 14-inch notebook on the market than law-abiding, of course, is the highest in the case of screen brightness test results, if appropriate to reduce the brightness, I believe will bring longer periods of time.
Summary
Aluminum-magnesium alloy material, texture stronger, more compact body of E420s and E220s in the pursuit of cost-effective E-series in slightly out of tune, which is the elite version they are marked with the reason for clearer market positioning, the E420s and E220s into the new S series launch is well deserved, this test belong to the S420 and S220 correspond to the Department of performance, portability, quality, comfort, price and service requirements of certain individuals , fashion users. dell xps m1330 battery
