Archive for Compal board LA-9981P, revision 1.0 as indicated by the R10 suffix, roughly 5.9 MB. The name does not reveal whether it holds a schematic, boardview or firmware, so open it and identify the contents before use. Compal numbers its laptop motherboards in the LA-xxxxP format, and such documents are used to trace rails, check power sequencing signals and locate components when diagnosing a dead or shorted board. Make sure the board number and revision printed on the PCB match before relying on the files.
