USB-C and Thunderbolt port failure
The XPS 13 has no USB-A or proprietary charging port — all power and data runs through the USB-C and Thunderbolt ports. This concentrates daily wear onto two or three connectors. Mechanical wear, bent pins, and board-level pad damage from repeated cable stress or tension are the most common causes of charging and connectivity failure. A port that only charges in one orientation or requires the cable to be held in place should be assessed before the damage reaches the board pads.
