Schematic for the Dell XPS 8900 desktop, referencing N170, Dell part number XJ8C4 and an M.2 variant, supplied as PDF in a 1.37 MB RAR. Dell boards are usually identified by a five-character part number, so checking the label on the motherboard against XJ8C4 is the first step. The diagram supports tracing standby and main power rails, reviewing the M.2 slot wiring and following front panel and power button signals. Open the extracted pages in any PDF reader.
