Frayed Cables
Cables can get frayed at either end of the AC adapter cable that comes from the AC adapter brick to the DC-in power port on the computer or the power cable.
This issue may occur if the cable is subjected to undue stress by incorrectly wrapping the cable, wrapping the cable too tightly, or cable twists.

Exposed Wires
If the cable is frayed or cut in any way, this may expose one or more internal wires. If the cable is frayed or cut, or any of the internal wires are exposed, you must immediately discontinue using the AC adapter.

Cut in Cable
A cut in the cable may appear at the flexible joints near the adapter brick or the connector. These flexible joints are designed to allow the cable to bend when being wrapped around the adapter brick, but over time the cable can become brittle and cuts may appear. A cut may also appear if the cable is rubbing against the edge of an object, like a desk or chair.

Pin that is bent or broken
The adapter pin may become bent or break entirely if it is not plugged into the DC-in power port of the computer correctly. Removing or inserting the cable at an angle or forcing an incorrect AC adapter may cause the center pin of the adapter or the DC-in power port to become bent or broken.

Cable Loose and Open AC Adapter
If you have a cable that is loose, try disconnecting the cable and reconnecting it. Ensure it is firmly connected. If the cable continues to be loose, check for bent or broken pins or damage to the connector on the computer or the cable.
If there is damage to the cable that is causing the issue, the adapter and or cable must be replaced. Contact Dell Technical Support for repair options that are available in your region.
