Circuit diagram in PDF format for the Compal LA-3031P laptop motherboard, and no revision or retail model is stated in the name. Compal is a major ODM, and its LA-numbered boards turn up in notebooks sold under several brands. Repair technicians use such schematics to trace standby and main power rails, check the charging circuit and follow signals between the chipset, EC and connectors. Any PDF reader opens it, and the LA number on the board should be checked to confirm a match.
