Dell 130W USB-C AC Adapter
This model requires a proprietary 130W USB-PD handshake to initiate charging. If the adapter's internal logic chip or the communication pin within the Type-C connector fails, the laptop's Power Management Integrated Circuit (PMIC) will reject the power source entirely as a safety precaution. This results in a 'plugged in, not charging' state or a total failure to recognize the power input.

USB-C Port / Motherboard Assembly
The USB-C ports on the XPS 17 9700 are soldered directly to the motherboard and act as high-stress mechanical points. Over time, thermal expansion and physical leverage from the charging cable cause fatigue in the lead-free solder joints, breaking the electrical continuity required for the CC1/CC2 pins to negotiate power delivery. Since the ports are not on a separate daughterboard, a port failure typically necessitates specialized micro-soldering or a full board replacement.
