Compal LA-9063P motherboard schematic at revision 1.0, supplied as a 1.76 MB PDF. The name gives no laptop brand or model, so identify the target machine by the LA-9063P silkscreen on the PCB. LA-xxxxP is the Compal ODM numbering pattern, and such boards were built for several brands. Use the sheets to follow power rails from the charger and PWM controllers, check signal paths and locate components when chasing a short or a no-power fault. Confirm the revision printed on the board matches before trusting part values.
