Adjustable DC Adapter for Dell / Alienware
Connector: 7.4 × 5.0 mm | Power Modes: Up to 360W
1. Product Overview
Designed for compatible Dell and Alienware laptops, this adapter features a recessed button for power-mode selection, color-coded LED indicators, and a memory function that saves your last setting.
2. Setup and Operation
- Keep the adapter disconnected from your laptop while changing modes. Connect it to the charger and turn on the power.
- Locate the recessed button inside the circular opening on the adapter.
- Press briefly to cycle through the modes in the order below. Avoid holding the button down, as this may cause continuous switching.
| Mode | LED Color | Power Setting |
|---|---|---|
| 1 | Blue | 360W |
| 2 | Green | 300W |
| 3 | Purple | 240W |
| 4 | Yellow | 180W |
| 5 | Red | Below 150W |
- Check the LED color to confirm your selection, then connect the adapter to your laptop.
The selected mode is saved automatically and restored the next time the adapter is powered on. A steady white light indicates operating status.
3. Compatibility and Power Requirements
- Confirm that your laptop uses a compatible 7.4 × 5.0 mm charging port.
- Select the appropriate mode for your laptop and ensure your charger can supply the required power. Selecting a higher mode does not increase the charger’s rated output.
- The red mode is intended for devices requiring less than 150W and is unsuitable for high-power operation.
4. Troubleshooting
If the button does not respond, the LED flashes, or the laptop displays an adapter warning:
- Disconnect the adapter from the laptop.
- Check the power connections and ensure the button opening is clean and unobstructed.
- Disconnect power for 10 seconds, then reconnect it.
- Verify the selected mode before reconnecting the laptop.
If the issue continues, contact customer support.
5. Care and Safety
Keep the adapter dry and protect it from moisture. Do not disassemble or attempt to repair it yourself.
VI. Frequently Asked Questions
Q: The button does not respond. What should I do?
Check the power connection and make sure the button surface is clean and unobstructed. If the issue persists, disconnect power for 10 seconds and restart.
Q: Can I skip gears directly?

A flashing light typically indicates a power mismatch or an unstable connection. Ensure the connected device’s power requirement matches the selected gear, then reconnect.

Yes. The device has a memory function and will automatically resume the last selected gear when powered on again.
Q: Which DELL laptop models are compatible?
