T420: New business models benchmarking

Every time when talk about ThinkPad appearance will feel poor vocabulary, words seem to describe the black has been written by ThinkPad Successive editors. Well, T420 appearance tone is still one word: black. Of course, T420 housing material is also not changed, from the T61 series began, the polyethylene composite material was applied on top of the aluminum-magnesium roll cage, so that the shell maintains high wear resistance, heat resistance, and good matte feel. At the same time, aluminum-magnesium roll cage can be reduced by 30% of the impact, to better protect the safety body.
Earlier said the T420 had the same appearance with other ThinkPad laptop, we take a look back on it in the appearance of the biggest changes with the previous generation T410: screen ratio changes. It emerges from the T61 widescreen start, ThinkPad T series has been using 16:10 screen size, and in the T420 which has completely changed the screen size into a more contemporary popular of 16: 9.
What changes has brought by 16: 9 screen ratio for the T420? First, the overall visual effect T420 significantly more slender. At the same time because of screen ratio changes, T420 screen height is relatively short than T410, it also has a certain relationship with narrow screen frame. In addition T420 screen metal hinge relative some narrow to T410, but do not know whether this is relationship with the proportion of the screen changes. If you use T410, you can get this driver from here: lenovo t410 drivers.
In addition, T420 does not adjust the size of the keyboard area, although the body width becomes narrow. They reduced the rarely used left and right mouse button which under the TouchPad.
Because the screen ratio adjustment to reduce the size of the border for T420, but this does not hamper T420 microphone settings in the top of the screen, and the camera is in a formed around each array layout, which coincided with 720p pixel camera phase with the formation of a new video series T assimilation system.
On the front of T420, the SD Card Reader cannot find as T410 have. T420 move it to the left and right side of the rear fuselage, this design is more conducive to the use of SD cards.
The main difference in the rear fuselage is T420 arranged a charge off function USB interface in the edge of the DJ11 interface. And the interface in the T410 age is on the left side of the fuselage. In the rear fuselage adding a USB interface such as a wired mouse more conducive to long-term use of this type have peripheral products.
There are two points in T420 interface design is disappointing.  T420 latter half of the right side of the interface is too crowded. There we saw the Express Card slot and SD card reader overlap, USB interface and eSATA interfaces overlap, and the wireless LAN hardware switch is also arranged there. If you use this laptop, you can get drivers from here: lenovo thinkpad t420 drivers.
Finally, a sad news: IEEE1394 interface from the T420 officially retired from the ThinkPad T series.
ThinkPad control function is very powerful. Full size keyboard design and increase of ESC and the Delete key, allowing users to use in their daily work more smooth freely, this is also since T410 listed on, in ThinkPad Lenovo makes big changes, not the exception T420 also continued the advantages in the keyboard, or on the keyboard T420 compared with T410 basic did not change, including the design of the touch pad.
T420 machine upgradeability still inherits the advantages of previous generations, hard drives, memory upgrades can be easily disassembled. Compare annoying is the memory module, the disassembled memory cartridge is designed only one memory slot, another memory slot in the innermost of the fuselage (almost directly below the keyboard), if users want to upgrade, he need disassemble the keyboard.
On T420, no doubt hardware change is the biggest, after the first generation Core processor upgrade to the second generation of Core processors, the T420 is not configured graphics card case can get a very good performance experience, its main reason should be considered integration of not less than the entry-level single significant "core graphics" Intel graphics HD3000.
The T420 model is equipped with Intel Core i7-2620M dual nuclear power plant thread processor with 2.70GHz clock speed, Core frequency up to 3.40GHz, in addition it also has up to 4MB of level three cache, while consuming only 35W. Intel Core i7-2620M, although belonging to more high-end i7 series, but we can put it as a top version of i5 series processor.
