Hi, my NUC8i3BEH seems to be dead - when I connect power, the green on board LED is lit constantly, but no video signal or any other signs of life... I tried with and without RAM, M.2 SSD or SATA HD. Held the Power Button for more than 20secs. Nothing. No HDMI output whatsoever. I did not tamper with the BIOS or its settings.
What can do? Can I measure somewhere on the board to get more info about the issue? Are there schematics available for the board?
Any help is appreciated, thank you.
To clarify your answer - Power Button LED is the LED located on the Power Button (see the image). Is it ON when you connect the power cord?
If you meant the that the Power Standby LED (on the board) is illuminated? That is correct.
It's only the onboard, green standby LED that lights up when I supply power. The blue LED on the power button does nothing. To me that looks like the CPU is not even running.
Agreed. Sounds like the unit is dead.
After verifying that your warranty is still active (here: Determine if Your Product Is Still Under Warranty), you need to directly contact Intel Customer Support to initiate the RMA process (you cannot do this through the forums). Here are pages where you can lookup contact information, including local/country phone numbers, by geography:
You can use the online forms service or email, but I actually recommend calling them directly. The above links provide local or toll-free numbers in most countries and support most local languages. You could also use the chat service (start here: Intel Customer Support Chat), but understand that this service is offered in English only and is subject to the normal (9:00-5:00 M-F) office hours in the Pacific (UTC-8) time zone.
Hope this helps,
Thank you for posting on the Intel® communities.
