Circuit diagram for Compal mainboard LA-6841P, a 1.15 MB PDF without a stated revision or laptop model in the name. LA-xxxxP is the Compal ODM numbering scheme, used on boards supplied to several notebook brands, so the PCB itself is the best way to confirm a match. A technician can use the schematic to follow power rails from the charger to the CPU, check signals around the EC and chipset, and find component values when a rail is shorted. Check the board revision on the PCB before relying on details.
