I had the same issue with 2 NUCs running RHEL 7.1 Shouldn't be related to OS changes...this should have no effect on hardware, bios...seperate systems. I suspect the power button itself is faulty. Happened on 2 of my NUCS, I raised support tickets with Intel and sent back and they replaced under warranty.
Shouldn't be related to OS changes...this should have no effect on hardware,
There is a bug in the BIOS, and somehow Linux suspend triggers this bug.
Many Linux users are reporting the same problem:
According to Intel’s release notes, BIOS Version 0038 fixed issue where system with Linux Ubuntu cannot resume from sleep:
My NUC was on BIOS Version 0040 when this happened.
Unplugging the CMOS battery for a minute reset the BIOS and my NUC was able to boot again.
Here are detailed instructions for unplugging NUC’s CMOS battery:
1) Unscrew the 4 screws from the bottom cover and remove the bottom cover.
2) Removed the 2 screws securing the motherboard.
3) Remove the Audio/Mic bezel.
4) Lift the motherboard from the Ethernet port side as shown on this video: https://www.youtube.com/watch?v=2EPZQUaJozk
5) Unplug the CMOS battery for a minute.
Reassemble NUC in reverse order.
I can see there is a new BIOS version that you can try, you can download it here:
Please be aware that we are still investigating on this issue but we haven’t had any luck in duplicating this behavior.
Please try the latest BIOS version with a BIOS recovery; please check the steps to do a BIOS recovery.
I look forward to hearing from you!
Both 0040 and 0041 continue to cause this suspend issue. I will be downgrading back to 0038 in order to avoid this problem.
I would advise in trying to duplicate this error that when placing the system in suspend to leave it for at least 24 hours in this state.
Can i suggest an additional design flaw with this device. In order to avoid having to open up the device and irreparably damaging ti, can a pinhole reset be implemented on the next generation? It would significantly save your support team from having to initiate a RMA and time and frustration for us users.
We appreciate your feedback in this matter and will definitely take into consideration your feedback for future improvements on our devices.
Please take into consideration Intel does not test nor validate Intel® NUC on Linux*; however, we know that a lot of Intel® NUC owners are successfully using many different Linux* distros.
Intel suggests you check your Linux* distro’s website, communities and forums for peer assistance on this matter.
Additionally, like in Windows* it is important to make sure all drivers are installed successfully on your Intel® NUC in order to ensure best performance.

This is one of at least fourteen threads in this forum which address Intel's 'Linux Suspend > Dead NUC' intermittent defect, dating back to August 2014.
The good news is that a workaround exists which means you can at least avoid getting your NUC bricked by this defect, and it involves using methods other than a short press on the Power button to wake a sleeping NUC – ie: wake-on-USB and/or wake-on-LAN.
