Schematic in PDF form for Compal motherboard LA-3451P, with no laptop model given in the name. Compal uses the LA-xxxxP numbering, and the same board can appear under more than one brand, so match the number printed on the PCB. A schematic like this lets a technician trace power rails, check the power-on sequence, follow signals between chips and find the parts to test when a rail is shorted. It opens in any PDF reader, and the component names should be compared with the actual board.
