Lenovo CG520 board NM-A801, revision 1.0, as a boardview file (BDV in the name) in TVW format, about 4.17 MB. The NM- prefix is the numbering used by LCFC, the Lenovo-owned ODM, and Compal boards before it, so the number on the PCB is what identifies the design. Load it in Teboview or a compatible reader to search components and nets, locate test pads and follow power rails while diagnosing no-power or short faults. Make sure the board shows NM-A801 Rev 1.0 before using the placement data.
