Wiring and circuit schematics for the Compal-built LA-9911P main board, revision R1.0, delivered as a 1.07 MB RAR archive. No laptop brand or model is named, so match the board by the LA-9911P code on the PCB rather than by the product label. Once extracted, the diagrams help a technician follow the standby and main rails, check the embedded controller and SPI flash connections, and find test points around the charging circuit. Revision differences can move or change parts, so confirm the R1.0 marking on the board.
