NUC9i9QNX thunderbolt issue

On a few occasions, the thunderbolt ports have disappeared. They still showed as enabled in the bios, but were not listed in the thunderbolt control center and no devices would connect. I had to disable thunderbolt in the bios, reboot and then enable it again, after which the ports worked ok.  To Intel, are you aware of this? Anyone else noticed this?

Are you using the latest TB3 v66 drivers from Downloadcenter.intel.com?

Yes I am.  When this first happened I uninstalled and reinstalled the v66 drivers, but it made no difference.

In my previous life (now retired) I was a software tester and troubleshooter. It was that natural fault finding instinct that suggested to me the idea of disabling and re-enabling the thunderbolt ports in the BIOS. This looks like a BIOS bug.

Decca, Thank you for posting in the Intel® Communities Support.


I just wanted to check if the problem with the Thunderbolt ports on the Intel® NUC still persists and if you need further assistance on this matter?

It hasn't happened since I posted about it, but I have not been in the BIOS settings very often recently. It seemed to crop up after numerous visits into the BIOS to tinker with cooling settings.

On that note, none of the cooling settings except "Fixed" help to solve the annoying fan speeds going up and down like a yoyo. Any work going on to sort this out?

Decca, Thank you very much for sharing those details.

 

Perfect, excellent, it is great to hear that so far no more problems are showing related to the Thunderbolt ports of the Intel® NUC 9 Extreme Kit - NUC9i9QNX.

 

In regard to the noisy fan, that is a different subject and in that case, what we recommend will be to submit a new thread for that specific issue so we can better assist you with that matter and trying to fix that specific problem.

 

Let me apologize for any inconvenience.

 

Regards,

Albert R.
