Schematic of the Compal LA-4993P board, revision 1.0, packed into a 717 KB RAR archive. Aside from the board code and revision the name carries nothing, so the notebook brand and model are not identified. The LA-xxxxP numbering belongs to Compal, a Taiwanese ODM producing laptops for other brands. After extraction, view the diagram in a PDF reader to follow the DC-in and charger path, measure standby and main rails at test points, trace EC and BIOS connections and locate the part responsible for a short. Match the PCB marking first.
