Schematic for the Compal LA-7553P laptop board in revision 0.2, packed in a 1.13 MB RAR archive. An R0.2 document is an early engineering version, so verify critical component values against the real PCB. The diagram still shows how power rails, the embedded controller, charger and main chipset are wired, which is what you need to trace a missing voltage or find a shorted part. Compal uses LA-xxxxP numbers on boards supplied to many laptop brands. Match the silkscreen revision before work.
