When I press power off in windows 10 the NUC does no longer power down. Same when I select shutdown from CentOS. I'm running all the latest drivers according the Intel drivers tool. I used to work so not sure what has caused this change. Any pointers?
I did a clean install of windows 10 (to rule out CentOS) and it still happens that when I select shutdown in windows start menu, I do exit windows, screen goes black as expected, yet the NUC does not power off.
The power LED stays solid blue and I hear the NUC is still on.
This happens from time to time so I maybe 1 out of 10 times it does not power off.
Any pointers where to look that could be the reason for the NUC to not power off?
Thank you for posting on the Intel® communities.
In order to check this behavior further could you please provide the following information?
1- Before the issue started, was there any software or driver update?
2- Does the issue happen if you try to power off the Intel® NUC by pressing the power button? You may test this following these steps:
3- Have you tested with minimal configuration? For instance, removing non-necessary devices, USB drives, using only 1 display, etc?
4- Have you tried loading BIOS defaults?
5- Please provide details about the devices connected to the Intel® NUC, please also include brand and model of displays and type of cables used:
Also, please run the Intel® System Support Utility (Intel® SSU) and attach the report to this thread to gather more details about your system.
1- Download the Intel® SSU and save the application on your computer.
2- Open the application, check the "Everything" checkbox, and click "Scan" to see the system and device information. The Intel® SSU defaults to the "Summary View" on the output screen following the scan. Click the menu where it says "Summary" to change to "Detailed View".
3- To save your scan, click Next and click Save.

1. I have had this issue on several occasions, cannot link it to a specific software update (eg. I had it after a BIOS upgrade, restart after that bios never happened and I had to power down by removing power plug, and it happens seemingly random)
2.I already had mapped the power button to shutdown, pressing power button did power off the NUC (but so does using the windows power off option, only problem is that it does not always work)
3. As said I had this when I did a BIOS update, the restart at the end of the update did not happen and at that time I had a very minimal install
4. I have the BIOS defaults
5. Monitor is lg 27ul850 monitor (usb-c connected now but the issue also happened with HDMI connection), mouse and keyboard Logitech using USB receiver (but it also happened with other wired keyboards and mouses)
A long press on the power button does eventually shutdown the NUC.
This sounds like a bug that was fixed in the BIOS years ago, but the fix seems to disappear and the bug re-manifest on every new NUC. The BIOS team has seen this happen time and again, but somehow it slip through the cracks every generation...(sigh!)
