Nu10i5 won't shutdown or sleep

[marcinnuc]

NUC does not shut down, always boots up after 3 seconds

OS: windows 10

Drivers: Intel® Driver & Support Assistant + chipset driver manually

I have the same issue like here Nuc i7 10th won't shutdown - Intel Community. I've tried all hints posted there. I think it happened after some BIOS update, but I tried reverting the BIOS with yellow jumper to versions 51, 52 and 53 with default settings and nothing helped. I tried Ubuntu and Windows. It seems that this is not a problem with the operating system. I tried unplugging all USB devices and changing RAM memory.

Hi @marcinnuc 

As you probably know from the post you referenced above, I solved similar problem by resetting BIOS to default settings. Since it didn't helped in your case I suggest try the following:

1. Disconnect the Power Cable and using tweezer, disconnect the CMOS Battery Connector (item "G", on figure 2 in the Technical Product Specification). Reconnect the battery after 15 minutes. In order to reach this connector, you need to remove the bottom cover and the SSD.

2. If the above not helps, try to change the Sleep Type from Modern Standby to Legacy S3 Standby. Read the instructions in my post how to do this. 

Hope this will help

Success!

tldr disconnecting the CMOS battery connector fixed the shutdown issue, changing the sleep type fixed the sleep issue.

I struggled with this problem for about 2-3 months. After reading a similar thread, I thought all that was left was to return the NUC, like the author of that thread did.

Removing the CMOS battery for 15 minutes fixed the problem with NUC not turning off, but the sleep mode still did not work. There were 2 symptoms, the screens turned off but the NUC continued to work or the screen flashed black and immediately returned to the desktop. Switching the sleep mode to legacy s3 solved this issue and for me it is ok, I don't need the newer mode.

Surprisingly, disconnecting the battery caused the date to be invalid, but my custom settings were saved (I only changed the temperature at which to turn on the fan). Well, the settings didn't reset but somehow it helped for the problem of this topic. If someone has similar problem, restoring default settings or switching to recovery BIOS may not be enough. By the way, it's pretty hard to disconnect and reconnect the CMOS battery connector.

Thanks Leon for your help, I'm glad I don't have to return my NUC.

i spent several days with the same shutdown issue and only removing the CMOS Connector solved it.

indeed it was not easy and i guess a second time the pins will not survive it.
I hope it will never happen again.

Any idea how to avoid it or is it really a one time solution?

Can you guys do me a favor and look into the windows 10 working bios updates.

I just want to know if this may be inflicting future generations.

Looking for commands;

shutdown /i

shutdown /r

The battery is essentially keeping the clock alive (it's part of CMOS), so normal to lose time when you unplug.
You typically can't change sleep type without also reinstalling Windows. Did you do that as well?

Hi Marcin,

I'm glad that the problem is solved. BTW, I agree that the CMOS battery plug is hidden in its receptacle. That why I suggested to use tweezer to carefully pull its cable in order to remove the plug from the receptacle.

Hi @n_scott_pearson, no, you don't need to reinstall Windows after changing the Sleep Type. You need to set Windows into SAFE Boot mode, before doing this change. This is the link to instruction how to do this.
