Schematic diagram in PDF for the Compal LA-D993P laptop mainboard, revision 1.0, about 4.5 MB. Compal uses the LA-prefixed numbering for boards it manufactures for several notebook brands. The circuit pages let you trace power rails from the charger input through the system regulators, follow enable and power-good signals, and identify the parts behind a short. Pair it with the matching LA-D993P boardview to find components physically, and confirm the PCB revision printed on the board first.
