Compal schematic in PDF form for board LA-J272P, with the platform code FDV42 in the name. Compal uses the LA-xxxxP numbering pattern for boards it makes for various laptop brands, so the board number is the key reference rather than the retail model. Open it in any PDF reader to trace power rails, follow enable signals and find where a short may sit. The name does not give a revision, so compare the revision silkscreened on your PCB with the title block before trusting part values.
