Schematic in PDF form for the Compal LA-9201P motherboard, packed in a 2.02 MB rar. Compal is the ODM behind LA- numbered boards supplied to Dell and other brands. The diagram lets a technician follow power rails, the power-on sequence, charging circuitry and signal paths, and read the expected voltages at each regulator. It pairs well with a boardview to locate the physical parts. Check that the board revision in the schematic title block matches the one printed on your PCB.
