Compal LA-7981P motherboard schematic in PDF form, 1.29 MB in size. The name gives the ODM and board number but no laptop brand, model or revision. Compal produces boards for many notebook brands and marks them with LA-xxxxP codes on the PCB silkscreen. The diagram helps with power sequencing checks, locating the components on each voltage rail and tracing signals between the chipset, EC and connectors. First confirm the code on your board matches LA-7981P, and note which revision it shows.
