Schematic for Compal motherboard LA-G871P, supplied as a PDF inside a 651 KB RAR archive. The name does not give the laptop brand, model or revision. Compal marks its boards LA-xxxxP and builds them for several brands, so check the title block for the project code and revision. Open the PDF in any reader to trace power rails, follow the power-on sequence and identify components on a shorted or missing rail. Verify the number silkscreened on the PCB before trusting values and pinouts.
