Circuit diagrams for the Compal LA-2921P laptop mainboard, revision R0.3, delivered as a 1.31 MB RAR file. Compal is a contract manufacturer whose LA-series codes appear on boards fitted to notebooks of several brands, so match the number on the board itself, not the case label. Inside should be a PDF schematic for tracing voltage rails, locating the source of a short to ground and checking component values. Before trusting part values, make sure the PCB revision matches R0.3, since early releases often differ from production boards.
