Lenovo G455 mainboard documentation, platform code NAWA1, on Compal board LA-5971P, stored as a 1.33 MB RAR. NAWA1 is the Compal project name that often appears in the schematic title block, so it is a useful cross-check. Compare the revision printed on the PCB too. Open the contents with a PDF reader or boardview software to trace the system power rails, check the charger IC circuit, and find which component pulls a rail to ground.
