I have been having similar issues with a newly purchased NUC6CAYH with Win 10 Pro.
Generally restart and hibernate seemed OK for the most part but shutdown would stall.
I found shutdown was more reliable when I disabled hybrid shutdown/Fast Startup.
This issue seems to be clouded by fairly frequent thermal trips being reported as part of POST even though the unit is barely warm and reported temps in visual BIOS are low.
Can you please provide the following information to better assist you?
The part number of the RAM:
Was there any change in the BIOS or OS before this started happening?
Can you please provide screenshots of the thermal trip messages/errors?
I hope to hear from you soon.
BIOS is latest - AYAPLCEL.86A.0040.2017.0619.1722, 19/06/2017
RAM configuration is 2 x Kingston KVR16LS11/4
This is a newly purchased machine so it has had Win 10 Pro installed with latest BIOS and Intel driver pack added.
Screen capture of the POST thermal trip warning attached (for what it's worth).
I am having sporadic issues with all shutdown, restart and hibernate actions.
Unfortunately, I struggled to get the jumper off the board but I used the BIOS recovery by power button method instead to re-apply 0040, which was successful. Is there any particular reason why the jumper method was preferred?
After this, I had a number of clean shutdown, hibernate and restart cycles, which was an improvement, but I did eventually see a thermal trip warning, without any obvious load having been placed on the system. My early observation is that resuming from hibernation events is mostly like to cause issues now. Also, hibernation sometimes appears to stall again. It seems that reliability of this degrades the longer the NUC is left connected to AC.
Resuming from hibernation state in one instance caused a failed POST warning instead,
Continuing with boot was successful.
In summary, the situation appears initially improved by re-applying the BIOS but still having spurious boot issues occasionally.
By removing the security jumper, you ensure that the BIOS update will take place without any issues as you don't have to interact with the Intel® NUC.
As for the image you provided, can you please get to the BIOS, press F9 (to load BIOS defaults) and then F10 (to save and exit)?
Please let me know how it goes.
I performed the F9 BIOS default load and since then reliability has dropped off steeply.
As I am not actively using the device currently, I ran the Intel Processor diagnostic one time to slightly stress the system (the reported temperatures from the diagnostic stated 50 degrees below max throughout) and then attempted a number of restart, shutdown and hibernate events. Many of which were unsuccessful. I have had some thermal trip warnings and POST hangs with no warnings. When I do get into BIOS, reported temps are still not above 50 degrees.
I disabled/re-enabled hibernation and ran disk checks etc. without any issues.
It seems that only about 10-20% of power events are reliable or do not require manual intervention with the power button, particularly recovering from failed hibernation or resuming from what appeared to be a successful hibernation previously.
