Schematic for a laptop mainboard with code APW5U, Compal board LA-C401P revision 1.0, supplied as a PDF in a 12.9 MB rar archive. The LA-XXXXP format is Compal's numbering scheme; the laptop brand is not stated in the name. Use the document to trace power rails, enable and power-good signals and charger circuitry while diagnosing a no-power or no-boot fault. Check that the PCB carries LA-C401P and revision 1.0 before relying on it.
