8. Troubleshooting
If you encounter issues with your power supply, refer to the table below for common problems and solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| No power to device | 1. Power supply not plugged in 2. Wall outlet not active 3. Loose connection 4. Device malfunction 5. Power supply failure | 1. Ensure power supply is securely plugged into a live outlet. 2. Test the outlet with another device. 3. Check all connections (DC plug, screw terminals) for tightness. 4. Test your device with another compatible power source. 5. Contact customer support if the power supply is suspected to be faulty. |
| Device receives dim or insufficient power | 1. Device power requirement exceeds 72W 2. Loose connection or damaged cable 3. Power supply degradation | 1. Verify your device's power requirements. If it exceeds 72W, a higher wattage adapter is needed. 2. Inspect cables and connections for damage or looseness. 3. If the power supply is old or has been subjected to stress, it may be failing. Consider replacement. |
| Power supply gets excessively hot | 1. Overload 2. Poor ventilation 3. Internal fault | 1. Ensure total wattage of connected devices is below 72W. 2. Place the power supply in a well-ventilated area, away from heat sources. 3. Discontinue use immediately and contact customer support if overheating persists without overload. |
