Compal schematic for the LA-9912P motherboard, revision 1.0, packed in a RAR archive of about 1.15 MB. The name gives no laptop brand or model, so identify the target machine by the board number silkscreened on the PCB. Compal is a contract manufacturer whose LA-xxxxP boards end up in laptops sold under several brands. Extract the archive and open the PDF inside with any PDF reader to trace power rails, follow enable and power-good signals, and locate the parts involved in a short or no-power fault.
