@OM105, Welcome to the HP Support Community!  

Thanks for reaching out about your query regarding Thunderbolt Port Issues on HP Spectre x360! 

We're thrilled to have the opportunity to assist you and provide a solution.  

If your HP Spectre x360's Thunderbolt port has stopped working, here's a step-by-step guide to help diagnose and resolve the issue:

Update BIOS and Thunderbolt Drivers:

• Ensure your BIOS is up-to-date. You can check and update it through HP Support Assistant or directly from HP's website.
• Update Intel Thunderbolt software which includes the firmware version for the Thunderbolt controller as well as the operating system drivers.

Check Thunderbolt Port Settings:

• Access the BIOS setup by pressing the F10 key during boot.
• Confirm that the Thunderbolt port settings are correct and enabled.

Reset User Account Settings to Default:

• Sometimes user settings might cause connectivity issues. Reset these to default from the BIOS setup.

Verify Cable Connections:

• Ensure that the cables are properly connected and there are no visible signs of damage.

Test the Thunderbolt Device:

• Confirm that the Thunderbolt device is detected in Windows Device Manager. If not, try testing with a verified working Thunderbolt device or cable.

Perform a Hardware Reset:

• Power off your notebook and remove any connected peripherals.
• Press and hold the power button for about 15 seconds to reset the system. This can sometimes help resolve underlying hardware issues.  

Hope this helps! 

Take care, and have an amazing day!

@OM105, Thanks for trying those steps and confirming the updates — that’s very helpful. Since your Spectre x360 detects other Thunderbolt devices but not the Lenovo Thunderbolt Dock Gen 2, it points to a potential compatibility or security setting issue rather than a hardware fault.

Here are a few things to check:

Thunderbolt Security Level

Go into your BIOS (F10 at startup) → Advanced → Port Options or Thunderbolt Settings.

Make sure the Security Level is set to No Security or User Authorization. If set to “Secure Connect,” you may need to manually approve the dock in Windows.

Approve the Device in Thunderbolt Control Center

Install or open the Thunderbolt Control Center from the Microsoft Store.

If the dock appears under “Attached Devices,” click Approve and Always Connect.

Check Power Delivery & Cable

Some docks require a high-speed, 40 Gbps-rated Thunderbolt 3/4 cable. Try the original Lenovo cable that came with the dock.

Device Manager Check

In Device Manager → System Devices, look for “Thunderbolt Controller” and ensure there are no warnings.

If you see the dock listed but disabled, right-click and enable it.

Windows Fast Startup

Disable Fast Startup in Control Panel → Power Options → Choose what the power buttons do. Sometimes Thunderbolt devices aren’t reinitialized properly with Fast Startup on.

Hope this helps! 

Take care, and have an amazing day!
