Schematic for the Compal LA-7531P mainboard at revision 0.1, compressed into a 1.25 MB RAR file. Only the ODM board number and revision appear in the name, with no reference to the notebook brand or model. As an early 0.1 draft, it may differ from production boards in some part values or placements. Extract the archive and open the PDF to follow standby and main rails, trace power-good and enable lines, locate the charger, EC and SPI BIOS chip and isolate shorted components. Confirm the LA-7531P marking on the PCB first.
