Early revision R0.3 schematics for the Compal LA-1971 mainboard, in an 818 KB RAR archive. A separate R1.0 release of the same board exists, so check which revision is printed on your PCB before using this one. Pre-production drawings can show different parts or values. The name does not state the laptop brand or chipset; LA- is Compal's ODM numbering. The document helps with tracing rails, following signals and finding faulty components. Open it with any RAR-capable extractor.
