Schematic for the Compal LA-9631P motherboard, revision 1.0, provided as a 1.59 MB PDF. No laptop brand or model appears in the name, only the board code and revision. Compal, a contract laptop maker, labels its mainboards in the LA-xxxxP style. With any PDF reader you can search net names, follow voltage regulators and the power-on chain, and find component designators when diagnosing shorts or a dead board. Make sure the PCB carries the same number and revision 1.0, because component values can differ between revisions.
