Even though our review unit has integrated Intel HD graphics, users can upgrade to NVIDIA NVS 4200M discrete-class graphics for only a little extra. The better graphics card might not be able to handle some games because it's a business graphics card with drivers related to that sector, but it will certainly enable users to partake in more graphics-intense tasks.

The specifications in our review unit are still decent. We would've liked to see slightly better specs at this price point, though. The combination of the Intel Core i5-2540M dual-core CPU, Intel HD graphics and 4GB of RAM is run of the mill as far as business notebooks go, but users will be able to multi-task fine, run almost all business applications and related tasks such as word processing, 1080p video, database work, and Web browsing. We were pleased with the Western Digital 7200rpm hard drive benchmark results; the drive runs faster than most included in business notebooks, so Windows bootup and program start times will be faster. Users also have the choice of upgrading to a 256GB solid state drive for even faster performance.
