Schematic for the Compal LA-8291P laptop motherboard, a PDF compressed in a 1.38 MB RAR archive. The name does not mention the notebook brand or the board revision, so check the title block inside against the PCB marking. Compal uses the LA-xxxxP code pattern on boards it builds for several laptop brands. The diagram helps trace power rails from the charger circuit through to the CPU supplies, identify signals in the power-on sequence and find components on a shorted line.
