In the era after the ThinkPad, business notebook market competition for various reasons become increasingly intense, Lenovo, HP, Dell, Sony and other major venders who turns into a moment let this market surging, compared to several other brands of products Dell's top business of the Latitude E-Family product has been relying on strong hardware configuration as well as excellent stability, scalability, and favored by business people, of which 14-inch E6430 is by virtue of solid appearance design and high stability made in order to group purchasing choice.

And most of the 2013 launch of the product, this product is also chasing the pace fought with the Intel upgrade to the new 32nm Core platform, we received this evaluation of the prototype is using the new Core i5 processor Core i5 highest performance 540M, 3GB RAM, 320GB 7200 rpm hard drive and a professional-grade NVS 3100M graphics card for business users with a very good application platform, but this product is the Latitude Z series has always been adhering to the high cost of style, so that the user's procurement costs can be greatly reduced.

E6440 with a 14-inch mold and 97Wh DELL Latitude E6440 Battery, 336x246x25-29mm body size compared to the normal 14-inch notebook is a bit bigger, but in thickness control is quite good, and the weight of 2.35kg and 2.76kg weight stand-alone travel Weight emphasizes protection for a business notebook, fairly fit to carry. Exterior styling stable atmosphere, with a good protection, hardware configuration is strong, excellent overall performance and screen performance, excellent power control, heating control overall better

From the point of view the overall appearance, E6440 overall appearance is close to Latitude E6430, but in some details of the deal is with no small change. A surface with etched and brushed metal effect processing, and before the effects of the E6430 matte surface differ, metallic-colored background with silver and white with DELL LOGO has a strong sense of fashion, and in addition, E6440 A surface no other decoration, the open matte surface and its business position are very contrast. Metal top cover for the screen provides a very good protection, we push hard in the test results using a finger is no subsidence roof, metal roof once again proved excellent protection capability, and for business users to say, excellent protection capability is exactly what they need.

Open laptop, TOSHIBA Satellite C75 with 6cell TOSHIBA Satellite C75 Battery, B and C - sides closer to the traditional design style Latitude E-Family product style, whole body with black tone, wide-brimmed design of the screen frame it appears that the body is very large. In the center of the screen frame is a high sensitivity 2.0 megapixel camera, and a microphone array were designed on both sides of the camera, array microphone pickup mouth with the camera as much as the pitch reaches 4cm, with the use of traditional mono microphone microphone pickup port position on the product are arranged in about 2-3mm camera compared to the position in such a stereo microphone pickup effect will be more outstanding
   
E6440 chose a 14.1-inch LED backlit screen 16:10, with most of the current notebook with a suction fit design compared to this E6440 still insist on the traditional lock-style closure, this approach although the opening and closing operation is relatively complicated, but the locking device to ensure the laptop will not turn on the move, so as to enhance the overall protective.


In the test, we actually tested optimized brightness 564cd/m2, and the contrast was 1344.1:1, color saturation, the test values ​​of 61.82%. From the final test results, E6440 is equipped with this LG LCD screen has good brightness and contrast, and color saturation can also be in the notebook LCD screen on the market on the middle level. So the test results indicate that E6440's screen can be better for business users, including the text, images and video playback display than similar products have better performance.

From the above test results, although NVS 3100M discrete graphics-oriented professional product, but in this part of the test results is quite satisfactory, the composite score of 5863 points and 5411 points of GPU test results indicate that this product can meet part of the mainstream gaming applications, while Core i5 540M processor is ran up to 7822 points, good results, this result indicates that the processor used in this product is for those who have high performance requirements of the processor, 3D games and applications also have a certain ability to cope, so users can purchase this product at ease with its operation of certain 3D applications.


Compared with the Latitude E6430, E5440 with 65Wh DELL Latitude E5440 Battery C-face small alterations, mainly in the right side next to the power button does not turn increase access function keys. While the keyboard is still using the traditional aspects of the structural design, button surface with a matte black brushed finish, with a relatively good feel, the input layout is also still using the pointing stick + touchpad dual input layout. E6440 touchpad area is relatively large, multi-touch feature, users can achieve multiple batter on the touch pad, zoom, rotate and scroll up and down web pages and other functions.

Comprehensive PCMark Vantage test results, with Core i5 processor + graphics card E6440 graphics processing power even in relatively strong demand for the Memories (memories), TV and Movie (video) and Gaming (games) three children are also have a good performance, which focuses on three sub-item test is that users often run home entertainment picture browsing, video encoding, decoding and gaming capabilities, and since this product uses processor performance than with higher performance graphics processing unit, So in this three strong demand GPU performance test subkey performance is relatively good, but the overall performance of the TOSHIBA Satellite C75D with TOSHIBA Satellite C75D Battery stronger, so in several other aspects of the test showed good, so buy this product users You can rest assured that their applications in all aspects of home entertainment.

In the graphic part of the test, we used the latest test software Futuremark 3DMark Vantage, which is the industry's first dedicated interfaces based on Microsoft DX10 API, Windows Vista operating system to create a comprehensive benchmarking tool that can fully play multiple cards, advantage of multi-core processors, in the current and future period of time to meet the PC gaming performance testing needs. 3DMark Vantage offers a new build of two graphics tests, two CPU test items, six characteristics of test items, and the introduction of four different levels of presets (Preset), can more accurately reflect the level of system performance. In the test, we will adjust the same system resolution 1024 × 768, using the test software provides Entry mode for testing.
   
We also used the TOPCON BM-7 spectral colorimeter E5540 screens were tested in the test DELL Latitude E5540 Battery we have chosen the right screen brightness, contrast and color saturation for testing. Brightness test, we let the monitor display full white screen on the center of the screen test, contrast test also used the same test method. Color saturation measurement to monitor when we were shown the red (R), green (G), blue (B), and then test the center of the screen color values. In the CIE color space R, G, B three points around the triangle area is the monitor can display all the color areas, the region's area and NTSC 1953 defines the scope of the RGB color space is the color saturation. sRGB standard definition of the color range of approximately 71% NTSC, which is normal CRT monitors that can be achieved.
