Background and Identification
The Lenovo ThinkPad Edge E520 (Model Number:1143), released in 2011, is one of many in the ThinkPad line and is no longer being manufactured by Lenovo. The E520 is identifiable by the ThinkPad logo stamped on the right bottom corner under the keyboard, the red "TrackPoint" nub on the keyboard, and its particular mouse pad layout. It featured over 10 available processors and was received very positively for its versatility as a small office/Home office computer.
