Compal LA-3071P schematics at revision R1.0, archived as a 1.28 MB RAR. The LA-xxxxP pattern is Compal's mainboard numbering, used on notebooks the company builds for other brands, so look for the code silkscreened on the PCB. A technician uses the extracted PDF to trace the standby and main power rails, verify voltages at test points, follow embedded controller signals and isolate shorted parts. R1.0 usually corresponds to a production board, but it is still worth confirming that the printed revision matches before relying on the drawings.
