My NUC7CJYH runs Win10-64bit, is fully updated, and my power settings in Windows are to never sleep. The NUC7CJYH goes to sleep anyhow. Is this a BIOS issue? I cannot find any manual or guide for my NUC7CJYH on Intel's site.

Thank you for your response.
Based on the report, we noticed that you are running and old version of the current BIOS for your Unit.
We would like you to perform an update and then let us know the results.
Here you will find the latest version of the BIOS:

Regarding the BIOS settings guide you will find all the information here:
As well, were you able to follow the steps recommended by Leon?
I hope to hear from you soon.
We just wanted to double check if you still need further assistance.
Please don't hesitate on contacting us back.
I hope to hear from you soon.
I've had additional difficulties, and I posted on this thread a week ago, including another upload from the SSU tool. Yet, my post seems to have disappeared into the ether. I am under severe time constraints and the NUC will be out of my possession soon as my daughter will be using it at a distant college. My fingers are crossed
First of all, your NUC's documentation can be downloaded from here:
Now, regarding your sleep issue, I have a couple of questions:
My post that disappeared contained another SSU output and a pair of entries from the Windows 10 Event Viewer. My NUC had crashed (sleeping or not I don't know as it was unattended) and, subsequently, Windows reported that it had recovered from an unexpected shutdown of unknown cause.
I don't know what CEC stands for. The link you gave me for is for the so-called "guide" I already have. It is barebones and has no BIOS documentation. So, I really have no idea what all the power related settings mean. I did successfully enable my USB mouse/keyboard to wake/boot my NUC. My NUC is mounted to the back of a rather large monitor so it is a bit cumbersome to reach for the power button. I do have display turnoff enabled in Windows (after 2 hours.) The NUC will sleep on command (or with the keyboard sleep button.) I just don't want sleep to be automatic.
My big issue now is that my LG monitor cannot detect the NUC upon bootup or waking. I've had to swap the monitor input (using its joystick menu) away & back to the NUC for it to detect a signal on its HDMI port. I don't know if this is a problem of the NUC or the monitor.
I can't say if the NUC is not going to sleep as I don't use the NUC except for testing and customizing for my daughter. It is intended to be used by her at college & she is leaving on the 13th so solving these troubles is a pressing issue now.
OK, here you have a link to bios glossary: https://www.intel.com/content/dam/support/us/en/documents/mini-pcs/BIOSGlossary_NUC.pdf https://www.intel.com/content/dam/support/us/en/documents/mini-pcs/BIOSGlossary_NUC.pdf

Hope this helps
CEC is capability for TV and NUC and other devices to communicate with each other over the HDMI interface and have things happen like the TV automatically powering on when the NUC is powered on, etc. I was asking because maybe the TV was somehow commanding the NUC to go to sleep (though I didn't think this particular capability actually existed).
Leon has provided you with the links to the available BIOS parameter documentation. I personally think this documentation sucks; parameters should be explained in context. I think that the TPS for each board should completely define and explain all of the BIOS settings for that board. Many other board manufacturers do this; Intel should too.
I have seen the issue with the monitor not waking after sleep cycle many times. This bug has been in the Intel HD Graphics driver for many years, so don't get your hopes up that a fix will be soon forthcoming. I have *never* seen a case where a monitor doesn't work when booting up, however.
You are almost certainly correct, Scott, about the monitor likely working at boot. But, that requires a hard shutdown with the power button first, as there's no GUI to work with. I'm so busy with work & getting everything else ready for my daughter's move to college (500mi away so I can do little for her after this week) that I've had little time to test drive her NUC & monitor. As a matter of fact, this is her 2nd UHD LG monitor, the first having crapped out after 2 days. Not the display but rather the monitor could not detect a UHD signal over HDMI, only FHD & below. That alone took several hours for me to troubleshoot & I'm obviously very short on time at this point.
The only reason I know the NUC is actually functioning, with no display, is that when I toggle the monitor's inputs through its menu, the diplay becomes active. However, this morning I had to toggle twice so I'm concerned my daughter will be stuck with a useless computer next week. And this input toggling is obviously not a workable solution for my decidedly non-tech daughter. Besides, the whole point of the sleep cycle is lost if I have to have her hard reboot the NUC with its power button.
I monkeyed with the monitor's very limited settings to disable any power saving but this does not help. Obviously, toggling the monitor's inputs from HDMI-1 to HDMI-2 is doing something to make the signal detectable. Perhaps that's the clue that will allow one of you helpful fellows to suggest a solution. I kind of suspect the monitor but I have no way of testing it & getting it replaced in time. I do have another 4K enabled computer but it's not running Intel hardware.
In my case, since I have a whole slew of NUCs and Compute Sticks under test -- as well as my own development, multimedia, etc. systems -- I use KVMs to connect them to a much smaller number of keyboards, mice and monitors. This exacerbates the issues with monitor connections (especially for my primary display, a 40" 4K Samsung TV, as the 4K KVM is, um, sensitive). What I do on all of my systems is disable Monitor Sleep. This means that the monitors doesn't use their best power savings features, but they do stay connected better. I suggest that you do the same...
Hope this helps,
By monitor sleep, are you talking about the LG monitor's power settings, which I noted I had disabled, or Win10's turn off display feature? I do have Windows turn off at 2 hrs, which I'd previously noted. I'm running out of time to run these tests but I could peruse the Event Viewer for any display related warnings.
I do wish to maintain an automatic display turn off within Windows' power settings, as I wouldn't want her monitor on all night with a static screen if she falls asleep while Netflixing. I have disabled sleeping on her NUC as I may from time to time have file syncing running in the background. That's pretty much the extent of the remote managing I've planned on. I could run a VNC session but I'd have to get permissions to get through her school's firewall.
Yes, I do mean Monitor Sleep in the Windows Power settings. You make up for this by enabling the Blank Screen screen saver. It's not perfect, but it works consistently...
