Disconnecting (or replacing) the cmos battery shall not affect the warranty. This is normal, however not convenient procedure. In order to get access to the battery and the battery connector you need to remove the main board from the NUC enclosure: CMOS Battery on the Intel® NUC . Such procedure requires some technical skill in order to not damage some sensitive components or disconnect some cable. Any way, if you decide to do this by your self, disconnect the battery connector and reconnect it after some 15 minutes. Of course all the procedure have to be done with the power cord disconnected.
I'm attaching image showing the cmos battery connector.
Hope this helps

Thanks for your reply, I'm happy to try unplugging the cmos battery but I was told via the live chat that It could affect the warranty and at this stage I could get a replacement. Could Someone from Intel confirm that I am able to try this without affecting the warranty?

Regarding your question, it will not affect your warranty options as long as the unit does not present any physical damage. Once you follow the procedure be careful.
If you have more questions, please let us know.
Hi Amy, Unplugging the CMOS battery has not resolved the issue.
