Schematic set covering two Compal motherboards, LA-8131P and LA-8133P, revision 1.0, compressed into a 1.51 MB RAR. The name gives no laptop brand, so identify the machine from the board number printed on the PCB. Compal schematics are commonly used to trace power rails, follow the power-on sequence, find EC and charger signals, and locate a short to ground. The PDF inside opens in any PDF viewer. Use it alongside a boardview if one is available, and check that your board revision is 1.0.
