Schematic diagram in PDF form for the Compal LA-D131P motherboard, project code BIZY1, revision 1.0, packed in a RAR archive. The LA-xxxxP pattern is Compal's own board numbering, and Compal builds boards for several laptop brands, so the board number matters more than the model name. Use the sheets to follow power rails, the charger and EC circuits, and signal paths while diagnosing no-power or short faults. Confirm that the revision silk-screened on the PCB matches r1.0 before trusting values and part references.
