Engineering-stage schematics for the Compal LA-9869P mainboard, revision R0.3, in a 1.42 MB RAR file. The file names no laptop brand or model, only the ODM board code that Compal prints on its PCBs. Because 0.x revisions often come before final production, compare component markings with the actual board before trusting every value. After extraction, the diagrams support tracing power rails and signals, checking the charger, CPU core and memory supplies, and finding test points while diagnosing no-boot or no-power symptoms.
