Board layout file for Compal motherboard LA-K811P, revision 1A, platform code GH47H, delivered as a 3.26 MB RAR archive. The laptop brand is not stated, but the LA-xxxxP pattern identifies Compal as the ODM, and the silkscreen on the PCB carries the same code. Extract it and open the board in a boardview viewer to locate chips, connectors and test pads, follow nets and check for shorts on power rails. Confirm the revision on the board reads 1A, as parts shift between Compal revisions.
