Compal LA-9104P schematic at revision 1.0, distributed as a PDF inside a 3.42 MB RAR archive. The LA-xxxxP pattern is Compal's laptop motherboard numbering, and the laptop brand built on it is not stated in the name. After extracting with any archiver, the PDF lets a technician trace power rails, follow the EC-controlled power sequence and find components on a shorted line. Confirm the board number and revision printed on the PCB match LA-9104P REV 1.0 before trusting values.
