- Connect to Device: Insert the DC output connector (the smaller plug) firmly into the power input port of your HP computer or monitor.
- Connect to Power Outlet: Plug the AC input cable (the larger plug) into a standard wall power outlet.
- Power Indicator: A blue LED light on the adapter will illuminate, indicating that the adapter is receiving power and is ready for use.


4. Operating Instructions
Once connected, the adapter will supply power to your compatible device. The blue LED on the adapter indicates that it is powered on and functioning correctly. Your device should now power on or begin charging its internal battery, if applicable.
- Ensure all connections are secure before powering on your device.
- If the LED does not light up, check the power outlet and all cable connections.
5. Maintenance and Storage
Proper care will extend the life of your power adapter:
- Cleaning: Disconnect the adapter from the power outlet and your device before cleaning. Use a soft, dry cloth to wipe the surface. Do not use liquid cleaners or solvents.
- Storage: When not in use, store the adapter in a cool, dry place, away from direct sunlight and moisture. Avoid tightly winding the cables to prevent damage.
- Inspection: Periodically inspect the adapter and cables for any signs of wear or damage.
6. Troubleshooting
If you encounter issues with your power adapter, refer to the following common solutions:
- No Power/LED Off:
- Check if the AC input cable is securely plugged into both the adapter and the wall outlet.
- Ensure the wall outlet is functional by testing it with another device.
- Verify that the DC output connector is fully inserted into your device's power port.
- Intermittent Power:
- Ensure all connections are stable and not loose.
- Inspect cables for any visible damage or fraying.
- Device Not Charging/Powering On:
- Confirm that the adapter's specifications (voltage, amperage, wattage, connector type) match your device's requirements.
- If the adapter's LED is on but the device isn't responding, the issue might be with the device itself.
