Laptop motherboard schematic for Compal board LA-5581P at revision R2.0, supplied as a 1.22 MB RAR archive. The name lists no brand, CPU or GPU, so treat the board code as the only identifier. Compal produces mainboards for many notebook vendors under these LA-series numbers. The drawings help when tracing a missing voltage back to its regulator, checking the EC and power-button logic, or finding which components share a shorted rail. Confirm the PCB revision matches R2.0 before using it for component values.
