Problem of connecting Lenovo Thunderbolt 3 Graphic dock with X1 carbon 6th

Hi, everyone, 

 

I meet a problem of connection. I install the driver but the computer seems not to recognise the graphic dock.

 

I cannot find my thunderbolt controller in the rest of picture 1, and I also cannot find thunderbolt in device manage. 

 

does anybody know how to solve it?

 

Thanks

Thunderbolt NOT found in device manager for X1 Carbon 6th 2018 in Windows 10 1903

Hi,

 

as title written, TB3 cannot be found in Device Manager, while already enabled in BIOS (1.40):

  • Installing TB3 successfully from lenovo support with latest version;
  • ERROR arises while install TB3 FM.

 

The error is "no active thunderbolt controller found in this system or thunderbolt software is not present in this system"

The BIOS setting is listed hereTIM图片20190816231950.jpgTIM图片20190816232046.jpg

 

 

 

 

And I can also not find Thunderbolt software in device manager. But "service" has thunderbolt service.

It was the recent BIOS update. If you go here:

https://pcsupport.lenovo.com/us/en/products/LAPTOPS-AND-NETBOOKS/THINKPAD-X-SERIES-LAPTOPS/THINKPAD-...

 

and scroll to 1.38 (n23uj16w.exe), download and install that. (Note: you might encounter a message about Secure Rollback being enabled in your BIOS.... you'll need to disable that and try again.)

 

After rolling back the BIOS, I rebooted and instantly everything was working again.

 

[UPDATE] After doing a software update from Vantage with the rolled-back BIOS, it said there was critical Thunderbolt firmware to install. So I did that, and on a whim decided to re-update my BIOS to the newest version. Things still work! So it would appear that in both our cases, the BIOS was updated before the Thunderbolt firmware update, which lead to the problem. Had we updated the Thunderbolt first, then the BIOS, everything would have been fine.
