Replacing bad CMOS battery or jumper

I had to pull CMOS jumper out and then back in to get my 8i7HVK to turn on once after I unplugged it and moved to another room and once it just shut off on its own and needed the CMOS to be reset. Everything on the NUC is up to date and its been working fine for a few days. I don't want to just start pulling at the battery as it seems to be taped onto the board in some way covered by tape. Should I replace the battery and/or the jumper cable and if so does anyone know the exact steps? The instructions listed for other NUC's don't seem to exactly apply. Thanks.

Hello Andrew2864

 

 

Thank you for joining the Intel® community.

 

 

I would like to verify what the current status of the NUC is.

 

  1. Run the utility.
  2. Click on "Scan" to get the scanned system.
  3. Once the scan is complete click on "next".
  4. Use the "save" option, save the report to your desktop.
  5. To attach a file, you must click the "Attach" option on the bottom right-hand corner of the response box.

 

We recommend not unplugging or removing the CMOS battery as that may void the warranty and it doesn't have any impact on powering the unit, only saving the BIOS settings, in case you are facing a dead CMOS battery you I would recommend applying for the warranty of the NUC, bear in mind that it was purchased in less than 30 days the warranty can be applied on the place of purchase, or the warranty could be applied by contacting the Intel technical support local GEO.

 

 

Hope this helps.

It has power now and has been working fine for 4-5 days. I was not able to turn it on twice but both times that was remedied by unplugging the CMOS battery jumper and plugging it back in after a few seconds. I haven't tried making any changes to the BIOS settings and never have. The system is booting to the OS and is currently working perfectly. I attached the config file below.

Hello Andrew2864

 

 

Thank you for the information.

 

 

I would like to share with you that after reviewing the report that you have shared with us I noticed that your system is running with a memory out of specifications (2133 MHz), this system supports DDR4-2400+ 1.2V SO-DIMM (https://ark.intel.com/products/126143/Intel-NUC-Kit-NUC8i7HVK https://ark.intel.com/products/126143/Intel-NUC-Kit-NUC8i7HVK). If possible you could test unit with the supported memory (if you change the memory please complete a CMOS reset).

 

 

Allow me to share with you the tested peripherals for the Intel® NUC:

Also, I see that your system has the BIOS 0044; there have been releases for the BIOS 0047, 0048, 0049. You could try to update the BIOS one by one. See the steps below.

Hi Intel, can you provide more information on the 2 pin connector for the CMOS RTC battery. NUC CMOS batteries have a 2 pin connector which looks like some kind of mini Molex or JST type connector. You can find plenty of CR2032 CMOS batteries with connectors on eBay or Amazon, but there are at least 4 variants of 2 pin mini Molex or JST connectors.  

 

Intel - can you please tell me what the exact type of connector is for a NUC6i3SYK and NUC6i5SYH (they should all be the same). For example : JST 1.25m pitch -or-  Molex type "picoblade", etc.

 

Thank you !
