Compal schematic for the LA-A331P motherboard at revision R0.1, packed in a 982 KB RAR archive. R0.1 is an early engineering revision, so component values and some nets may differ from later mass-production boards. The LA- prefix is Compal's main logic board numbering, and Compal builds boards for several laptop brands. Extract the archive, open the PDF and use it to trace power rails, follow signal paths and find test points. Before relying on it, check that the board number and revision printed on the PCB match.
