Compal schematic for motherboard LA-A491P at revision 0.3, supplied as a 3.04 MB PDF. The name gives no laptop brand or model, so identify the target machine by the board number silkscreened on the PCB. The LA-xxxxP pattern is Compal's own numbering, and the same board ends up in notebooks sold under several brands. Use the sheets to trace power rails, follow signal paths and find the parts involved in a short. Confirm that the board carries revision 0.3, because component placement and values can change between revisions.
