Troubleshooting Adapter Issues
The adapter cable and power cables may get frayed or cut, and wires may become exposed at either end of the cables.

If the damage is severe enough to expose wires, you should discontinue using the adapter. To check the adapter, cables, and adapter port on the laptop for any damages:
- Unplug the adapter from the wall outlet.
- Unplug the adapter from the PC.
- Check the adapter and cables (including the power cable) for signs of physical damage or overheating.

- Unplug the adapter from the wall outlet.
- Connect another device on the wall outlet to verify if the wall outlet is working correctly.
