Error: BIOS has detected unsuccessful POST attempt(s) - BOXNUC8i5BEK2

[TomG1]

Product:  BOXNUC8i5BEK2
Memory: 2x Crucial 8 GB DDR4-2400 SODIMM
Drive: Kingston A1000 NVMe 240 GB
OS: Windows 10 Pro 20H2 (19042.610)
BIOS: BECFL357.86A.0085

Every time when the NUC reboots the Intel NUC Logo shows for a long time. Then it reboots again and I get the message.

BIOS has detected unsuccessful POST attempt(s).
Possible causes include recent changes to BIOS Performance Options or recent hardware change.
Press "Y" to enter Setup or "N" to cancel and attempt to boot with previous settings.

I did not change anything on the hardware setup or in the BIOS nor do I have an external hard drive plugged in. When I shut down the computer and start it again the message doesn't appear.

Tried fixing the problem with:
Recovered BIOS BECFL357.86A.0085
Recovered BIOS to BECFL357.86A.0083 (downgrade)
Used a second Kingston A1000 NVMe 240 GB drive.

I am out of ideas and doesn't find something on the internet. I need the unit to reboot after a windows update without my intervention.

Hello TomG1, 

Thank you for posting on the Intel® communities.   

In order to better assist you, please provide the following: 

1. Run the Intel® System Support Utility (Intel® SSU) and attach the report generated:  

• Open the application, check the "Everything" box, and click on "Scan" to see the system and device information. By default, Intel® SSU will take you to the "Summary View".

2. I understand that you do not have any external drive connected, but do you have any other external device connected through USB?  

3. What happens if you reboot and disconnect every single external device not needed just for testing?

ad 2) Yes that is correct. No external drive is connected. Only HDMI, Ethernet, USB Keyboard and USB Mouse.

ad 1 and 3) Didn't to the test because I "fixed" it.

I found a old Samsung SSD EVO M.2 120 GB drive and tested it. With this drive I have no problems. Reboot and shutdown works as indented. So I checked if there is a firmware update for my Kingston drive. There was and so I installed the latest firmware. After that. Both Kingston drive work had now issues. I can reboot the NUC without any problems.

Solution: Update Kingston firmware to latest.

Hi Sebastian_M_Intel, I am also having the same issue. I have headphones, mouse and dongle plugged in - would any of these be the issue for me? This didn't start happening until recently when I updated my BIOS in the recent lot of Intel updates....
