Schematic in PDF form for the Compal LA-G521P laptop mainboard, revision 1A. Because the name names no laptop model, identify the machine by the board number silkscreened on the PCB rather than by brand. Compal uses the LA-xxxxP pattern for its designs, which are sold under several laptop brands. The diagrams let a technician trace power rails, enable signals and power-on sequencing, and pair well with a boardview for physical component locations. Any PDF reader opens it, and text search helps find net names quickly.
