Timeless. As we've already noticed in the smaller T420, the tested and tried Thinkpad design has practically been left untouched on the outside. However, the new Sandy Bridge hardware will now do its job inside. Moreover, we discover a pro graphics card and the Optimus technology.

While it's a bit thick and heavy for a 15-inch laptop, the $1,299 Lenovo ThinkPad T520 offers business users everything they need: good performance, durability, and security. Of course, you also get Lenovo's trademark fantastic keyboard and accurate pointing stick. Add in wide viewing angles for the matte screen and extra-long battery life and you have a sound investment.

Lenovo ThinkPad T520 Review
Source: Student Buying Guide English
The Lenovo ThinkPad T520 is a strong all around laptop. Its strong chassis and durable design will ensure it survives the rigors of campus. The things to like about this notebook are almost too numerous to list; the legendary ThinkPad keyboard lives on and continues to be the gold standard. The touchpad and pointing stick are excellent as well and offer great feedback. The 1600×900 screen has good image quality and plenty of space (resolution) for multitasking. Overall performance is fantastic for everyday use. The standard 6-cell battery yielded about 7 hours of battery life, on par with Lenovo’s estimates. Lastly, the T520 has plenty of input/output ports including a docking station port. The list of things I don’t like is pretty short; the speakers are terrible and it’s rather heavy/large. To address the last issue, Lenovo offers the smaller 14” T420. Overall I highly recommend the T520, it’s hard to beat – especially if you get it on sale like we did!

Still, six hours of battery life and fair performance are complemented by the tremendous build quality, to make the Lenovo ThinkPad T520i a solid all-round business laptop. Budget dictates it isn’t the best-equipped machine on the inside, but it can be upgraded to be, and its reliability and design make it an attractive alternative to the excellent Sony VAIO S.
