When you power on, hold the power button for 3-4 seconds and see if the system will get to the recovery menu.
Nope. Holding the power button for a few seconds, it does the same thing. Powers up for about 1 second and then right back off.
Had you left it running and then found it powered off? If so, a good possibility is that the power brick failed. Do you have a source for borrowing another one to try?
Voltage at the internal power header is 18.79 volts. When powered on only drops slightly to 18.72 volts.
The behavior you describe points to a hardware failure.
You already performed the proper troubleshooting steps to diagnose the problem and as Scott said, the only chance here is a faulty AC adapter.
If you can try another 19v AC adapter will be great to confirm. If not then I recommend you to contact our Customer Support Channel for warranty instructions.

Thanks darwinb for the reply. Contacted customer support last week and followed their troubleshooting steps. Pretty much the same things I had already done (as most techies would, but that's okay, better than shipping stuff around that's not actually broken). It is being RMA'd using SWR method. Depending on how quickly replacement is shipped out, could potentially receive it by end of week.
I'm a little disappointed and concerned though that there seems to be quite a few of these devices with power problems across many of the various models (and assorted other problems). So a replacement could end up with a short life also. Thus once the warranty period is up it's basically a brick. I believe the initial warranty is 3 years. Does that get extended at all for the RMA replacement device? Would be pretty sad to have an nice, and expensive, device like these be turned into a brick at only 3 years old. I have 2003 era (10-12 year old) consumer grade DELL notebooks still running strong 24/7 for their entire life. Would really love for this NUC to have that kind of longevity. Currently that looks kind of doubtful though.
Thanks for your response. Looking forward to receiving the replacement.
Oh for got to mention. Yes, tried another 19v AC adapter with same results.
