Early draft schematic, revision R0.2, for the Compal LA-9531P laptop board, provided as a 1.13 MB RAR file. Later revisions 0.4 and 1.0 of the same board also exist, and production units usually follow the final one, so compare with your PCB before trusting values. The name carries no notebook brand or model. Compal's LA-xxxxP codes identify its own designs. Extract the drawings to follow voltage rails, EC and power sequencing signals, and to locate parts around a shorted line.
