Getting exactly the same issue with some Latitude 7480 and 5490. CTRL key seems stuck, randomly but mainly when the computer is started without any external keyboard plugged.
I suspect some kind of driver issue, or something that was later fixed in a Windows update.
At the time, I upgraded the Windows build to 1809 for users who were having this problem. None of them reported issues after that.
However, we have a lot of other 7390 users still on 1803 who have not experienced this error, so I am none the wiser really.
The 7390 as a whole has been pretty bad. We have had a lot of users reporting BSODs recently, a number of users who's TPM chips randomly disappear for no reason and several warranty callouts as a result.
Yeah - we are suspecting something similar with a faulty driver... However, I hope I'll not be your black bird here, but just wanted to let you know that this problem has been reported just like you said by some users running 1803, but it became more and more important when we have deployed the 1909 version.
Our Service Desk is keeping drivers and BIOS up-to-date but doesn't help a lot. Agree with you regarding the overall quality of those 7480 products, getting more BSOD than usually, driving to motherboard replacement. Also, if Intel Speedstep is enabled, users are complaining for bad performances, overheating, and consequently noisy fans... Anyway, will keep digging with this CTRL issue and will update this post if I found any permanent fix.

Hi,
Getting exactly the same issue with some Latitude 7480 and 5490.
CTRL key seems stuck, randomly but mainly when the computer is started without any external keyboard plugged.
Have you found any proper solution for this ?
Thanks
