Circuit diagram for the Compal LA-9103P motherboard, revision R0.1, supplied as a 1.25 MB PDF; the name does not say which laptop brand or model uses the board. The LA-xxxxP pattern is Compal numbering, and such boards were built for several notebook brands, so the PCB silkscreen is the reliable identifier. Use the sheets to trace power sequencing, check rail voltages against the design values and locate parts when hunting a short. Early revisions can differ from production boards, so verify against the physical board.
