Schematic in PDF form for the Compal LA-J191P laptop motherboard, 27.9 MB. The name gives no laptop brand or model, so match the LA number and revision on the PCB before relying on it. A Compal schematic covers the power sequence, voltage regulators, rail names, connectors and signal paths, which helps trace missing rails, find the source of a short or check enable signals. It opens in any PDF reader, and text search works on net names when the drawings are vector-based rather than scans.
