Compal LA-7552P schematic, revision 0.1, supplied as a 1.11 MB RAR file. The name provides only the ODM board code and the revision, with no notebook model or brand. An earlier R0.03 draft of the same board also circulates, so pick the revision closest to the one printed on your PCB. Once extracted, the drawing helps follow standby and main power rails, check enable and power-good signals, locate the EC and BIOS chip and isolate shorted components. Pre-production revisions may differ slightly from shipped hardware, so cross-check values on the board.
