Schematic diagram for Compal board LA-B731P. The name does not say which laptop brand or model uses the board, so confirm the device from the PCB marking. Compal's LA-xxxxP numbering identifies Compal as the ODM, and its boards ship under several laptop brands. The PDF can be opened in any reader and is used to trace power rails, follow signal paths and identify the components behind a fault. Make sure the board number and revision printed on the motherboard match before relying on it.
