Schematic for Compal board LA-B012P, with revision given as r10, probably meaning 1.0, in a 3.06 MB PDF. The laptop model is not named, so rely on the LA-xxxxP code that Compal prints on the PCB to confirm it matches. Technicians use these sheets to trace power rails, check the charger and PWM sections, and find values for parts that need replacing. Any PDF reader opens it, and the sheet index helps you jump between circuit blocks.
