- Ensure the adapter is in a well-ventilated area and not covered by objects that could trap heat.
- If the adapter becomes excessively hot to the touch, disconnect it immediately and allow it to cool. If overheating persists, discontinue use.
- No Power Indicator Light (if applicable):
- Verify the power cord is fully inserted into the adapter and the wall outlet.
- Check for power at the wall outlet.
- Loose Connection at Laptop Port:
- Ensure the DC plug is fully inserted into the laptop's charging port.
- If the connection remains loose, the laptop's charging port may be damaged, or the adapter plug may be worn.
