Compal LA-7912P schematic, revision 0.2, for an Acer laptop whose model name is not given, supplied as a 1.43 MB PDF. Compal numbers its mainboards with the LA-xxxxP pattern, and that code is usually printed on the PCB. As a 0.2 revision it may predate final production, so compare details on the board carefully. Technicians use it to trace power rails and signals, locate MOSFETs and regulators and isolate shorts. Verify the LA-7912P marking on your board before relying on it.
