Schematic diagram in PDF form for the Dell 5400, project EDC41, built on Compal board LA-G891P, delivered as a 2.37 MB RAR archive. The LA- prefix is the Compal ODM numbering style. A technician uses the schematic to follow power rails from the charger input through the main regulators, find enable and power-good signals, and identify components around a short circuit. Open it in any PDF reader, ideally alongside a boardview, and make sure the board number silkscreened on your PCB matches LA-G891P before trusting component references.
