Difference between revisions of "Lenovo Thinkpad T400 and T500"

It has a high performance CPU, even if Intel made no major improvements on this last Core 2 Duo offering. There are some models featuring a 6MB L2 cache that have slightly higher performance than standard ones, but the performance is nowhere near the later Core i-5 series. The CPU cooling is adequate for all CPU options. Higher performing models with ATI graphics require are only slightly noisier and warmer. The keyboard is quite durable but not stiff and with a noticeable poorer quality feel than previous generation Thinkpads. The slow decline in build quality becomes obvious since the T61 series.  

The chassis was a mixed bag, as it was not sturdier than on the T61 models and significantly less for the longer 15-inch models. In fact, Lenovo did not improve in any significant way the chassis of the T400 models and reused the previous T61 widescreen laptops chassis, resulting in a very poor result. Palmrest are particularly notorious for cracking since there are not enough supports and chassis rigidity below. On some laptops there is even a visible curving of the under chassis, on quite pristine models, due to poor manufacturing. The display hinges are overly engineered, with great durability. The integrated speakers are quite good, although their position, size and technology is not the best.
