Hi Intel won’t help advised me to post on here

Having problems with checksum cmos error on boot up


Done this already no joy

Flashed latest bios

Set to default

Changed the battery cmos one


Makes no difference

Clears the error on bios

But comes back any help would be much appreciated

Only thing I have not tired is jumpers but I don’t think NuC have them


Not done recovery bios either not sure that will make a difference on thank you

There are a lot of batteries that are designed - backwards - for Dell systems. Compare the colors of the new battery against the old to be sure it is correct.
Hope this helps,

The important question is: Have you have verified that the wire colors are correct? at the connector?

Hello , no I have not unless I remove the plastic cover from the battery to check positive and negative are correct , you would have thought black and red would be standard for bios battery ?

Just look at the colors at the connector; you don't have to worry about the colors being used differently. 

'You would have thought..." is an assumption. In the face of something not working, always, always eliminate assumptions; they will screw you up more often than not.

Ok, if the wire colors match the original ordering (and don't follow the Dell backwards ordering), then I can only conclude that the CMOS part is failing. This is not something that you can do anything about; it may mean replacing the unit.

Hello thank you for the info

I be really surprised the unit has gone wrong as once set the the ripen on bios every thing is working fine till I power off from mains then it will lose time only
To be honest am quite shocked at intel support them selfs


Any way I get some electrical conductive tape and make two new batteries see ifs a wiring issue that will eliminate that from the equation

Thank you

That's because your CMOS stayed powered, via the main power supply, until you unplugged it. When you unplugged it, it then drained and lost its contents (including the current date and time).
