Schematic set for the Compal LA-4991P board, revision 1.0, packed in a 734 KB RAR archive. Only the ODM board code and revision are given, so the laptop brand and model cannot be determined from the name. Compal designs and builds notebooks for many brands and identifies each mainboard with an LA-number on the PCB. After extraction, read the drawing in a PDF viewer to trace power rails, check the power-on sequence, find the charger, EC and SPI flash and locate components on a shorted rail. Confirm the board marking matches first.
