Schematic set for the Compal LA-B481P main logic board at revision R2.0, in a 1.60 MB RAR archive. A 2.0 revision points to a later design update, so boards marked 1.0 may have different parts or routing. Compal makes LA- boards for several notebook brands, and the name does not identify the laptop model. Unpack the PDF to trace power rails, find shorted capacitors, check EC and charger circuits and read connector pinouts. Match the revision silkscreened on the PCB before replacing parts by value.
