Many users encounter similar problems, and there are solutions to get your system back on track.
Here’s a step-by-step guide to troubleshoot and resolve the issue:
-
Check Hardware Connections: Start by ensuring that all hardware connections are secure. Power off your Mini PC and disconnect the Thunderbolt 3 device. Reconnect everything carefully, making sure all plugs are firmly attached.
-
Update BIOS: Sometimes, outdated BIOS settings can lead to compatibility issues. Go to HP’s official website, find the support page for your EliteDesk 800 G9, and check for any available BIOS updates. Follow the instructions provided to safely update your BIOS.

Reinstall Thunderbolt Drivers: Even if you’ve installed the Thunderbolt drivers before, it’s a good idea to uninstall and then reinstall them. Go to the Control Panel, find Thunderbolt under Programs, and uninstall it. Then, download the latest version from the HP support site and install it again.
-
Access Safe Mode: If your system won’t boot normally, try accessing Safe Mode. You can do this by turning on your Mini PC and repeatedly pressing the F8 key until you see the Advanced Boot Options menu. Select Safe Mode, then try uninstalling or reinstalling the Thunderbolt drivers again.
-
Check Device Manager: If you can access Windows, navigate to Device Manager by right-clicking the Start Menu. Look for any devices with a warning sign. If you find any, try right-clicking and selecting ‘Update Driver’ or ‘Uninstall Device’ and restart your PC.
-
BIOS Settings for Thunderbolt: Sometimes, you may need to enable Thunderbolt support within the BIOS settings. Restart your PC and enter the BIOS by pressing the appropriate key (often F10 or ESC). Look for Thunderbolt settings and make sure they are enabled.
- Consult HP Support: If you’ve tried all the above steps and the issue persists, it may be time to reach out to HP Support. Provide them with details about your problem and the troubleshooting steps you’ve already taken.
