Schematic in PDF form for Compal motherboard LA-K851P revision 1A, with project codes GH51Z and GH71Z. The name does not state the laptop brand or model, so identify the system by the board label. The LA-xxxxP code shows Compal as the ODM. Use the schematic to trace power rails and enable signals, check the charger and VRM stages, and find the components behind a short or no-boot condition. Make sure your PCB revision matches before relying on component values.
