A RAR archive of 1.19 MB with schematics for Compal board LA-7901P, revision R1.0. The file name does not name the laptop brand, model, or chipset, so the PCB silkscreen is the only reliable reference. Compal uses LA-numbered boards in notebooks it builds for several brands, and closely numbered codes such as LA-7902P are separate designs. The diagrams support tracing voltage rails, checking power-good signals, and locating the components on a shorted net. Confirm the revision matches R1.0 before replacing parts.
