6. Troubleshooting
If you encounter any issues with your Nucbox K6, please refer to the following common troubleshooting tips:
- No Power: Ensure the power adapter is securely connected to both the mini PC and a working power outlet. Try a different outlet if necessary.

- Windows Activation: If Windows requires re-activation after an upgrade or change, navigate to Windows Settings > System > Activation. Windows 11 Pro is pre-licensed and should activate automatically via the digital license linked to the motherboard.
- Performance Issues: Ensure the mini PC has adequate ventilation. Check background applications and close any unnecessary programs. Consider adjusting TDP settings in the BIOS for higher performance modes if needed.
- Fan Noise: The Nucbox K6 features a dual-fan cooling system. Under heavy load, the fans will increase speed to maintain optimal temperatures, which may result in audible fan noise. This is normal operation.
