Compal LA-B541P main board schematic at revision R0.1, a first engineering draft, packed in a 1.88 MB RAR archive. The lettered LA-Bxxx form belongs to Compal's later board numbering, and Compal builds these boards for several notebook brands. Because R0.1 predates production, designators and values may change on retail units. The diagrams still help trace power rails, read net names, check EC and power-good signals and locate shorted components. Extract the archive and compare the PCB silkscreen number and revision with the drawing first.
