Schematic in PDF for a Compal board labelled LA-L9431P, revision 1.0, packed in a RAR archive. The name follows Compal numbering but states no laptop brand or model. The diagrams let a technician trace power rails, follow the power sequence, check signal paths and read component values while diagnosing faults. Open it with any PDF reader after extraction. Verify the exact board code on the PCB, since similar Compal codes such as LA-9431P belong to different designs.
