Compal LA-A621P schematic at revision r03, with an extra 0903 token that is probably a date code, though that is not certain. The PDF is 972 KB, and no laptop brand or model appears in the name, so identify the target by the board number on the PCB. LA-xxxxP is Compal's mainboard numbering, used in machines sold under various brands. Revision matters here, because component values can differ between issues. Technicians use these pages to trace rails, test enable and power-good signals, and find the source of shorts.
