Compal LA-1381 mainboard schematics at revision R2B, packed in a RAR archive of 968 KB. The R2 revision with a letter suffix marks a later update to the design, so the revision printed on the PCB should agree before specific values are trusted. Compal builds notebook boards for other brands and uses this LA- numbering for them. After extraction, use the diagrams to follow supply rails from the adapter input onward, locate fuses, MOSFETs and regulators, and measure the expected voltages to isolate a failed stage.
