A 2.46 MB RAR archive containing the schematic for the Compal LA-B231P board, revision R1.0. Apart from the board code and revision the name carries no details such as laptop model or platform. The LA-prefix numbering belongs to Compal, the contract manufacturer behind boards sold under various laptop brands. Unpack the archive and open the diagram in a PDF reader to study rail generation, charger circuitry, and the nets around a shorted rail. Always compare the PCB silkscreen number and revision with this document first.
