Laptop new Model by Lenovo: T400 Review
The Lenovo ThinkPad proved to be an exceptional 14″ business notebook, giving almost unheard-of battery performance under modest running conditions. Nearly 10 hours of runtime with the extended battery easily puts this notebook into the all-day computing category. System performance with the Intel processor and ATI 3470 graphics was great, handling everything we threw at it, even some video games. The is not without its flaws though, having a decent amount of keyboard flex and a keyboard light that blinds you. Even with its flaws, with a starting price under $1,000 this notebook easily outperforms any other computer in its category.
• 10 hours of battery life with the 9-cell battery!
• Very bright LED backlit LCD
• Under normal conditions is very cool and quiet
• Hybrid graphics that let you switch between great 3D performance or great battery life
• Keyboard flex in a ThinkPad … the end of an era.
• Keyboard light that blinds you instead of just illuminating the keyboard

Performance
Lenovo ThinkPad T400 came with the Intel T9600 processor, clocking in at 2.8GHz, and jammed packed with 6MB of cache. For graphics, Lenovo included an ATI Radeon 3470 video card with 256MB of GDD̷ memory. A speedy 160 GB 7200 RPM hard drive was also included, which helped applications load without much lag. This notebook was outstanding for day to day use, and had enough power to handle most games around the office to kill some time. Half-Life 2 in native resolution (1440×900) kept above 30FPS even in heavy action scenes. Portal was another favorite that worked very well at native resolution, keeping framerates above 40FPS throughout most of the game.
For users who don’t wish to have as much 3D acceleration (or power consumption) during day to day work, you can switch between the Intel X4500 integrated graphics and ATI 3470 dedicated graphics. This switch can be made on-the-fly without a reboot. Not using the dedicated graphics resulted two hours of additional battery life.
wPrime is a program that forces the processor to do recursive mathematical calculations, the advantage of this program is that it is multi-threaded and can use both processor cores at once, thereby giving more accurate benchmarking measurements than Super Pi.
Battery Life
To get 10 hours of battery life from a notebook this size, most people think you would need a huge battery attached to the bottom of the case, another battery taking the place of the optical drive, and a big battery sticking out the back. With the T400 you can reach 9 hours and 41 minutes with the wireless enabled, screen backlight at 60%, and the laptop in integrated graphics mode using only the 84Wh 9-cell battery. In this situation the notebook is only consuming roughly 8.5 watts of power. In dedicated graphics mode under the same settings battery life falls by exactly 2 hours down to 7 hours and 41 minutes, and power draw increases to 10.5 watts. The 6-cell battery managed 6 hours and 4 hours and 28 minutes respectively.
Ports and Features
Port selection rates average on the T400, with 3 USB ports and no digital video output. You do have VGA, but it is not the best option if you want to hook the notebook up to an HDTV. As mentioned about in the Build and Design section, the T400 with the SD-Card reader option nixes one the PC-Card slot. For those thinking about using legacy external cards, you may want to reconsider that option.
One feature that has been on ThinkPads almost forever is the ThinkLight, which is a small white LED located above the screen that illuminates the keyboard. On every other model we have reviewed that has this light, it works as intended and gives a little light on the keys. On the T400 the shroud in front of the LED isn’t big enough, and the end result is a light blinding you. Your night vision is taken away and in the end it is a useful feature turned worthless by lack of proper design. Not exactly sure how it made it past quality control, but unless you have the screen tilted forward to an extreme degree you end up as blind as a bat.
Heat and Noise
The cooling system seemed greatly improved over the prior generations, letting the notebook run whisper quiet and very cool to the touch under most circumstances. I say most, since gaming did seem to make it run on the high side. When not gaming, one thing really working towards the system temperatures advantage was the very lower power consumption. Consuming almost half the power of the previous generation really helped reduce overall temperatures.
