Schematic for the Compal LA-5661P laptop motherboard, revision 1.0, in a 972 KB RAR archive. Compal is a major laptop ODM, and its LA-xxxxP numbers appear on boards built for several brands, so the laptop maker is not stated here. The circuit diagrams cover power rails, charger and EC circuitry, and signal paths, and help with diagnosing no-power or no-display faults. Open the PDF inside with any PDF viewer. Make sure the LA number and revision on the PCB match, because rev 0.4 differs.
