Schematic for the Compal motherboard LA-J891P, revision 1.0 indicated by R10, stored as a PDF in a 3.82 MB RAR archive. The name gives no laptop brand or model, so identification rests on the board number, which follows the Compal LA-xxxxP pattern silkscreened on the PCB. Use it to trace power rails, follow the power sequence and look up part values around a fault. Extract the archive, open it in a PDF reader and compare the board number and revision printed on the board first.
