Compal LA-1881 motherboard schematic, revision R1.0, packed into an 840 KB RAR archive. The name carries only the board code and revision, with no brand, model or chipset. Compal acts as an ODM, and its LA- numbers identify boards built for other notebook brands. Once extracted, the drawing helps a technician follow the charger and regulator circuits, check reset and power-good lines, and track down a short on a rail. Confirm that the PCB silkscreen matches LA-1881 and its revision.
