Compal LA-675AP motherboard schematic at revision 1.0, provided as a compact 1.01 MB PDF; the name misspells Compal as Compa. The LA-xxxxP format is Compal's mainboard numbering, with the AP suffix marking this board variant. No laptop model or chipset is listed, so identify the machine by the number printed on the PCB. The drawings help trace power rails, locate the charger and VRM circuitry and check signal connections when repairing no-power, no-display or short-circuit faults in any PDF viewer.
