Circuit schematics for the Compal LA-2522 mainboard at revision R2.0, packed in a RAR archive of roughly 1.18 MB. The short LA number without a suffix belongs to Compal's earlier board series, and no retail laptop brand or model appears in the name. A 2.0 revision suggests a later, production-level drawing. Technicians use such a set to follow the power-on sequence, measure expected rail voltages, identify the EC and BIOS chip connections, and locate parts near a fault. Verify that the PCB shows the same code and revision first.
