Schematic archive for Compal motherboard LA-4491P, revision R1.0, delivered as a RAR of roughly 1.28 MB. No brand, CPU or chipset is given in the name, only the Compal board number. Compal is a contract manufacturer whose LA-coded boards ship under many laptop brands. Once extracted, the diagrams help with tracing the charger and power circuits, finding the source of a missing voltage and identifying the parts on a shorted rail. Make sure the board code and revision on the PCB match before relying on the drawings.
