BOXNUC8i3BEH2 does not boot and shows unknown blink code

Since a couple of days the NUC8i3BEH2 does not boot anymore. The blue LED is on for about 25-30 seconds then off for about 5 seconds, repeating this pattern all the time. No beep codes are emitted and absolute no video output. Holding the ON/OFF button for some seconds doesn't change the behaviour. SSD disconnected, no change, the memory module works fine in another NUC device. Information about NUC blink codes states "contact support". Are there any ideas what happened and how to solve the problem? Installed OS is Windows 10 Pro (I assume 20H2) Thanks in advance HJM

Hi @HJM 

1. Which event (or what you did) before this problem started?

2. Was the NUC working before this failure occurred?

3. Do you see any video output (like Intel NUC logo for example)?

4. Open the NUC bottom cover and remove the Yellow BIOS Security Jumper.

5. Power ON you NUC. With jumper removed, your NUC should boot after 1-2 minutes into Configuration Menu.

Hello Leon,

1. Don't know, have to ask the user

2. Yes, NUC was working

3. No video output, not neither BIOS outputs nor INTEL NUC logo

4. Jumper removed

5. No, sorry, same blink code as before
