-
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.
