Schematic for a Compal laptop mainboard carrying project code GH47H and board number LA-K811P, revision 1A, in PDF form inside a RAR archive. The LA-xxxxP numbering is Compal's own pattern, and the same board is sold under various brands. Open the PDF in any reader to follow the power-on sequence, trace rails and signals, and check part values while diagnosing a short or no-power fault. Make sure the number and revision on the PCB match LA-K811P 1A before relying on the circuit.
