Compal LA-1671 motherboard schematic at revision R1.0, packed in a RAR archive of about 808 KB. LA- followed by four digits is the board code Compal uses for its notebook mainboard designs, and those boards were sold under several laptop brands, so the code printed on the PCB is what identifies the match. Extract the archive, usually to a PDF, and use the diagrams to trace power rails, follow signals between chips and find the parts on a dead or shorted line. Confirm that the board code and revision on the silkscreen agree before relying on any values.
