Schematic PDF for the Dell Latitude 3420 14-inch laptop, board 11282-1, version with discrete graphics (DIS) and the MLK project tag. Five-digit board numbers with a revision suffix follow Wistron's numbering for Dell boards. The RAR of 1.7 MB contains the diagrams used to trace power rails, the charger circuit, GPU supplies and power-on sequence. Confirm your board is the discrete-GPU variant and that the number on the PCB matches, as UMA boards differ.
