Clock stopping when disconnected from power

[MNott]

I have a STCK1A32WFC running Windows 10. The clock had stopped at a date from over a year ago. Bios updated within last 2 days​ to see if this would fix. Has helped when unit remains powered. However when disconnected from power the clock stops. This unit is stored unpowered for use with data logging equipment. I believe the internal battery is meant to keep RTC running. No "low battery" warning from BIOS during POST at start up.

MNott, Thank you for posting in the Intel® Communities Support. Just to confirm, the clock you are referring to is it the one in the BIOS or the one showing in Windows*? Is this problem recently, was the unit working fine before? Besides the BIOS update, If it is the clock showing in the BIOS, then even though you mentioned that you already did a BIOS update, we can alway try a BIOS recovery to the latest version 0038 to confirm if that way the problem gets fixed: https://www.intel.com/content/www/us/en/support/articles/000005902/mini-pcs/intel-compute-sticks.html https://downloadcenter.intel.com/download/28070/BIOS-Update-FCBYT10H-86A-?product=86612 You are correct, the Cmos battery is the one that keeps the clock updated in the BIOS, so if the problem persists after that and if the Intel® Compute Stick STCK1A32WFC is under warranty, you can contact the Intel warranty center in your region in order to replace the unit: https://www.intel.com/content/www/us/en/support/contact-support.html#@6 Regards, Alberto R.

​Hi Alberto

Thanks for your reply.

Both clocks are affected.

The unit hasn't been powered for over 18 months and that was only when setting up. It was on WiFi and updating automatically and so I didn't notice problem.

On performing a BIOS recovery. Since your reply I have downloaded the Bios recovery file.  F4 Bios recovery was not an option on the Bios menu so I reloaded using F7. A quick test shows this has not fixed the problem.

How long should the CMOS battery last?

The unit was bought over 2 years ago and so would be out of warranty.

Are there instructions available on how to change the battery?

Hi MNott, we are sorry to hear the issue persists. In reference to your question, based on the battery standards, the average lifespan of the battery is around 3 to 5 years, depending on the usage and the quality of the unit. The warranty of the Intel® Compute Stick STCK1A32WFC is for one year: https://www.intel.com/content/www/us/en/support/articles/000005948/mini-pcs/intel-compute-sticks.html And no, there are no instructions of how to change the battery of the Intel® Compute Stick, since based on the terms and conditions that process will avoid the warranty on the unit. Now, there are some reports of users that were able to replace it, so as an alternative, you can always look for the steps to replace it on a third party site as well as the information of where to purchase the new battery. Regarding the clock in Windows*, as an option we can always try an OS recovery, please see the instructions under the "To operate the system recovery" tab in the next link: https://www.intel.com/content/www/us/en/support/articles/000005885/mini-pcs/intel-compute-sticks.html Regards, Alberto R.

MNott, I just wanted to check if the information posted previously was useful for you and if you need further assistance on this matter? Regards, Alberto R. Intel Customer Support Technician Under Contract to Intel Corporation

Hi Alberto

The last response from you was:

· That the battery had more than likely gone flat

· Intel don’t provide instructions or any other details on how to change it – even what battery to source as a replacement.

· To browse the web for third party DIY instructions on how to replace the battery.

While I’ve had a quick browse, I haven’t had a project since where I’ve needed to use the Computestick and so haven’t attempted to change the battery.

I expect to in the next month or so.

I’ll update you once I’ve done so
