Compal LA-9981P schematic, revision 0.2, in a 1.87 MB RAR archive. The file name includes only the board code and the draft revision, with no laptop brand or model given. Revision 0.2 is an early engineering version, so some values or components may differ from production boards. Once extracted, the drawing helps technicians trace power rails and signals, follow the power-up chain, identify regulators, MOSFETs and test points and diagnose shorts or missing voltages. Compal prints these LA-codes on its PCBs; confirm the number and revision before relying on it.
