Schematic in PDF form, packed as a RAR archive, covering the Dell Latitude 3490 and 3590 laptops on the Compal LA-F116P motherboard. Compal uses the LA-xxxxP pattern for its notebook boards, and their schematics typically include power sequencing pages, rail names and connector pinouts. A technician relies on this document to trace power rails, follow enable and power-good signals, and locate the source of a short. Any PDF reader opens it once extracted; verify the LA number silkscreened on the board before trusting the diagrams.
