Lenovo ThinkPad E420s are the elite version of the Edge series of high-end models, it is in the ThinkPad tradition of models based on the number of added elements of fashion, created a new generation of standards for high-end business machines, simple appearance, exquisite design, strong performance and configuration, slim, lightweight body, undoubtedly those of us used to the traditional users of the machine to its ThinkPad series has a new look and desire.
Although previously we have from many sources to understand the information about it, but get real machine later, still a little surprised, it changes actually so great: smooth corners, shiny chrome frame, the integration of the metal bottom shell, like a mirror of the LCD glass, this is the familiar ThinkPad it? In addition to the red dot that is still alive and the body much of the ThinkPad logo, ThinkPad I did not find more then the other elements.
A change in appearance
Speaking from the first color, take E420s and other than the traditional ThinkPad machines, first discovered it is no longer the kind of color the color of black, similar to gray-black.
Information from the manufacturer to see is dark green, but I do not see how it is dark green, so that other colleagues read, no one can see it is dark green. Perhaps only in the sunlight, in order to show that touch of mystery it.
In hand machinery and control the opening and closing the screen, we can feel the rigidity of the body well, even from off the edge of the screen, its deformation is small, not like some brands of household machines in his hand always felt creak to ring, worrying will not fall apart. It is used in alloy cover with glass fiber, the entire bottom shell is made of metal, the intensity is high, pushing down the outlet without the slightest distortion.
The whole body is a kind of coating used, similar to the previous kind of skin texture coating 600E, but not exclusively, that feeling.
Another change is the ThinkPad logo itself, the letter i above points into a red, and light up automatically when turned on, of course, this change can not be regarded as new, because before the Edge series E40 model has been the case.
Bottom of the change is relatively large, E420s using the integration of the bottom shell, hard drives, like the original, can be extracted directly after the replacement. However, battery, memory is hidden in a body inside, purpose of doing so is self-evident, is to make the elite version of the ThinkPad Edge slimmer.
Review the history of ThinkPad models, we can easily find, ThinkPad generally accepted reason for the majority of users, it is important because they regard the user ease of use on the top, of course, including the maintenance convenient.
E420s out of the LCD screen using a high hardness of the glass without borders, making the B-side like a mirror. Nevertheless, it benefited from the superb anti-glare technology, not only effectively eliminate the phenomenon of reflection, leaving display unexpected.
Change the keyboard is relatively large, and before the Edge series machines, X120E, like, E420s also used a six-row floating island-style keyboard, in the row of buttons on the arrangements, such as volume, brightness, display switching, wireless switches, etc. Some commonly used function keys.
And we used the keyboard is not the same, F1-F12 keys and function keys for the switching, direct press these buttons, use the function keys F1-F12 keys to use, you must use the Fn key combination red corresponding button. Relative to the F1-F12, the majority of users when using the function keys a little more, this change added more fit the user's actual situation.
The use of chrome metal frame so that E420s have become more modern and stylish feel.
Second, the machine configuration
Dedicated network to get this E420s (4401-32C) using the CPU is i5-2410M, 4GBDDR3 memory, and AMD Radeon HD 6630M graphics card (2GB memory), is particularly worth mentioning is the E420s with a dual-drive configuration way, in addition to the common high-performance 320GB 7200 rpm hard drive, but also the additional use of a piece of Intel mSATA interface, 80GB SSD, because SSD read and write faster than mechanical drives, use it as the operating system disk, you can greatly improve the for startup, shutdown, and efficient access to large applications, this configuration, SSD prices still remain high in the current case, both the performance and capacity of the dual needs.
In addition to high-performance graphics card Radeon HD6630M addition, E420s also uses the Intel Core Graphics, both to meet the general application requirements, but also can greatly reduce the power consumption of the machine, thus extending the life of the machine. Two kinds of cards can be switched at any time, users can for each specific program, a separate set of high performance (discrete graphics) or power (Intel Core Graphics) mode, but this set is way better than the direct use of a general feeling key conversion convenient and practical.
Third, the external interface
From the configuration table, we can see, E420s provides some common interfaces such as USB2.0, RJ45, VGA, HDMI, eSATA, one headset jack, 4 in 1 card reader, etc., can be found attached to the arrangement of the interface Fig.
The first one on the right side USB port is a yellow, in the case of external power supply, USB devices can be powered directly. With the increase in personal electronic devices, daily travel time bag with three or four cases of electronic devices has been very common, and sometimes what the device will inevitably encounter a sudden no power, and this time if you have a bag E420s, it can be a good alleviate this predicament.
E420s using the HDMI interface is a very commendable place, connecting high-definition
Lenovo E420s battery flat-panel TV on the convenience, HDMI to be significantly better than the DP interface, the vast majority are used in flat-panel TV HDMI interface, HDMI is inherently for the audio and video designed with the transmission, the connection is also very convenient. Fourth, the performance test
E420s overall configuration is relatively high for its performance, we also have many expectations, let's specifically look at its true performance.
(A) CPU performance. We still use the SUPER PI software testing. E420s of one million and 200 million bits, respectively with 14.04 seconds and 32.167 seconds. From the results comparison chart we can see, the second generation of i5-2410M processor performance over the first generation of i7-740QM.
(B) hard drive performance. E420s Lenovo Enhanced Experence2.0 technology is the use of models, combined with solid-state hard drive, startup and shutdown speed can be achieved. This E420s are installing 64-bit version of Windows 7 Professional operating system to load during startup and a power indicator. Press the power button from the start time to start is completed, only 25 seconds. Shutdown
Lenovo ThinkPad Edge E220 battery speed is amazing, only a short 7 seconds. This switch speed have left a deep impression, which apart from its high-performance SSD outside, Enhanced Experence 2.0 also play an important role.
Here we use HD Tune Pro software for this mSATA interface SSD screenshot when tested. From the figure we see that it reached a maximum read speed of 203.3MB / s, average speed of up to 177.6MB / s, access time of only 0.1ms, no wonder the speed switch will be so fast.
E420s using another hard drive is Seagate 7200 rpm 320GB hard drive, the specific model is ST320LT000, 7mm thin part of a single platter drive, read and write typical line is relatively smooth.
(C) 3D performance test
With powerful graphics card and the power of the second generation of i5 processors, E420s test in 3D Mark 06 score of 7146 achieved, with this result, E420s enough to cope with the vast majority of 3D games needs.
Generally speaking,
Lenovo ThinkPad Edge E420s battery vary significantly not only in appearance by adding a number of elements of fashion and trends, even many advanced technologies used in the body of this high-end business. Something inherent in many ThinkPad E420s who has been in a good heritage, whether it is quality, performance and core technology. It should be said, this is a successful innovation. Combined with 3D in the upcoming blockbuster "Transformers 3" will appear ThinkPad Edge historic elite version of the figure, let us look forward to ThinkPad Edge Elite version in the film to have excellent performance at the same time, more expect it to have a more astonishing market performance.
