PDF schematic for the Compal LA-4731P mainboard, which the file name associates with the CQ35 notebook. Compal uses the LA-xxxxP pattern for its laptop board designs, and this board number is the reliable identifier when you match the document to a unit on the bench. The diagrams help with tracing power sequencing, checking the charger and voltage regulator circuits, and following signals between chips. Before trusting the values, check that the number printed on the PCB is LA-4731P and that its revision matches the document.
