Schematic for the Compal LA-4501P motherboard, revision R1.0, supplied as a compact 579 KB RAR archive. Only the board number and revision are given, so identify the laptop model from the label on the PCB. The LA-xxxxP pattern is Compal's ODM numbering, used across several laptop brands. Unpack the archive and open the drawing in a PDF viewer. The pages help when tracing voltages on each rail, following the power-on signals or finding the part pulling a rail to ground. Verify that the revision matches the board.
