Hi, I want to replace the rtc battery of a NUC6CAYH, but when I open the NUC, I cannot find the battery. Is there a document describing the procedure to replace the rtc?
Thanks in advance.

1. The procedure for CMOS battery replacement: https://www.intel.com/content/www/us/en/support/articles/000006787/mini-pcs.html CMOS Battery on the Intel® NUC
2. The battery is located on the board upper side. You need to remove this board from the NUCs case.

Hey Leon
My problem is: howto remove the board from the chassis ?
I have already removed the hard disk, two screws with which the board is attached,
the vga connector and the little plastic cover(around the HDMI connector etc.) at the back.
I also removed de plastic top chassis cover.
Then I can move the board a bit, but I can not remove it yet.
What else do I have to remove or unscrew?
I don't have NUC like yours. But I suggest to unscrew the screw holding WiFi adapter and removing this adapter after disconnecting the antenna wires. Please see this clip showing how to do this on very similar NUC:https://www.youtube.com/watch?v=MwqrfIdyvGw&t=300s Intel NUC Fan Replacement - YouTube
Hope this will help

Thanks to your tip, I managed to remove the board.
However the battery appears okay.
I was almost certain that the battery failed, because after a short power break, the clock was ok but not after a longer power break.
In the bios I found: "CMOS TIME NOT SET 1/1/2016 0, 0, 0".
Testing was done without an OS (thus no disk connected) to be sure that the problem did not come from the OS.
I suppose I will have to ask a new question to the forum.
Thanks again, Marc
I am trying to do the same. Can you tell me how you managed to remove the board. I did all above steps but can't get it out
I followed the clip suggested by LWAKSMAN: https://www.youtube.com/watch?v=MwqrfIdyvGw&t=300s
It is indeed for a NUC5CPYH while mine is a NUC6CAYH.
these are my steps:
- remove harddisk
- remove the network module
- remove plastic cover on the backside which covers the vga connector (it clicks into chassis)
- unscrew the vga connector and remove it
- unscrew the 2 screws (like in the clip)
- at last remove the systemboard as described in the clip (you have to use some force but not too much)
Thanks for your detailed reply. I managed to get the board out, but the CMOS battery voltage was OK and removing it to reset the CMOS memory did not get the NUC to work. I will have to return it.
