Schematic for the Lenovo ThinkPad E585, made by LCFC on board NM-B531, a design shared by the E485 and E585. The 1.49 MB RAR holds the circuit diagram for tracing power rails, following the power-on sequence, checking signals and finding component values when a board shows no power or a short. NM-xxxx numbers follow the LCFC pattern used for Lenovo laptops. Usually viewed as a PDF; verify the board number on the PCB before relying on the pages.
