Schematic PDF for the Compal JAQ10 project on mainboard LA-4311P, packed in a 993 KB RAR archive. LA- numbers follow Compal's ODM naming, and the board was supplied to various laptop brands, none of which is stated here. The drawings let a technician trace power rails, follow the power-on sequence, check the charging circuit and locate parts on a shorted line. Open it with any PDF reader, and confirm the board number and revision on the PCB match the schematic title block.
