Has anyone else experienced a strange power issue with their Nuc?

When I go to turn it off, the Nuc shuts down but nothing I do will turn it back on at this point. I need to pull the power and then try and turn it back on but even then it's not guaranteed to start. 

It should have the latest Bios, V27 I think. 

After some weird windows crashes I thought it was ram so removed a stick and it booted ok but still had restart issues so ran windows memory diagnostics on it and nothing came up for either stick of ram. 

Incidentally, the time on windows never gets set right. I have it set to update via the internet but if the box fails and a restart eventually happens the time is way out and I need to do another sync with the internet to get it right. Weird. 

It almost feels like the cmos battery is nearly dead and needs to be replaced but I've had computers last for years before even thinking that might happen. I've never actually had to replace a battery though. 

My monitor won't display the visual bios (it's a weird resolution bug) so I'm going to try and bring it in to work tomorrow and use one of the monitors there and see if I can see anything worth changing. 

Anyway, has anyone else had anything like this happen? Feels like it's either a simple solution or a rma process.

I have the Celeron 2820 model with bios v38 and have the opposite problem.  Turn it off but it always turns back on.  Will check to see if wake up on lan is checked. 
The nuc you have may have new firmware available.  Really great htpc units these are.

HTPC Intel Pentium G3258 cpu, Gigabyte H97n-wifi motherboard, , 8GB DDR3 ram, onboard  graphics. Hauppuage HVR 5500 tuner,  Silverstone LC16M case, Windows 10 pro 64 bit using Nextpvr and Kodi

Neither of our NUCs have displayed this behaviour, either the power issue or the time sync issue. I would check that the BIOS is latest (I know you said it should be), and try to reset the BIOS to defaults (remember to set your OS choices etc back if they need to be!) and see if it remedies it.

If you boot to an OS on removable media, do you get the same problem? i.e. ruling out a driver/OS issue rather than hardware.

Still having weird issues. 

When I shut it down it won't turn back on until I have pulled the network cable and put it back in a few times. 

If I shut the box down at 2pm and then restart it (whichever way I can find that works) at 5pm then the system clock shows 2pm. 

I need to check, but the last time I saw the bios it had the right time, I wonder if that's because it had just been booted to OS. If the bios time is out then surely that means a cmos battery replacement is a good start?

I don't have any wake on lan stuff set in the bios either. 

I've tried windows 7 and windows 8.1. Still need to get myself a linux distro to try properly.
