NUC 9 Extreme mit Core i9 und ASUS 2070 startet nicht mehr.


The NUC 9 worked flawlessly for the first few days and the speed was
very good.
In the evening I switched off the NUC 9 normally with the power button
on the front, by briefly pressing it, as always.
The next morning, switching on with the same power button was no
longer possible.
Neither a short press nor a long press has switched the NUC 9 on.
The Power Led never shone again.

I then tested a new power cable on a different socket, but that didn't
work either.
Then I removed the power supply and connected it to the power
independently of the NUC 9.   
All plugs from the power supply were without power except for the
10-pin plug had a voltage of 4.7 volts on the tab side and 5.1 volts on
the other row on the middle pins. Is that ok ???

I also tested the power switch and it works well, it has 0 ohms on the
connector when it is pressed.
Then I reassembled the NUC 9 to be sure that all plug connections are
correct. But the NUC 9 still does not switch on, whether you press the
power switch briefly or long, nothing works.
I noticed that when the power supply is connected to the power, the
LEDs on the gamer mouse light up until I remove the power cable
again. The power switch has no effect on the mouse lighting.

My guess is that the power supply is in sleep mode and can
no longer be activated.

Weiss da jemand Rat ???

Hello Auswanderer,

Thank you for posting on the Intel® communities.  

I would like to further investigate this for you, therefore, I would appreciate if you could provide the following information:

  • Pleases provide the exact model or part number of the unit.
  • Were any changes made prior to this behavior?
  • What is the BIOS version installed?
  • I understand that there a no lights on the unit, correct?
  • Were you working with BIOS default settings?

This information would be useful to identify the problem and look for a resolution.

Hello Esteban

Thank you for your answer.

Here are the identifications:

On NUC 9 Body :    S/N:   Deleting personal information.      SA: Deleting personal information. 

On Power Supply: S/N:   Deleting personal information.       P/N: Deleting personal information. 


There are no changes on this NUC 9,  it is new and was only 3 day's working.

The BIOS was installed, possible from the seller JIB, i don't know witch version.

The power-led around the power switch is always off now, when i push the power button. It was only the first 3 day's working.

I hope this helps you with my detail description, to find a solution.

I was again by the seller and he tell me, that he can not only order the power supply, even not when i do buy it again........Waht is the problem ???

Thank you and Best Regards


Hello Auswanderer,

Thank you so much for your response and the information provided.

Based on the behavior of the device, this seems to be related to the power supply of the device.

If the unit was purchased recently and if the unit still under the 30-day return policy we would strongly recommend checking the replacement options with them.

However, you can always contact us directly to continue with the assistance. To do so, please check the Support Contact Information.  There, you will be able to submit a service request and study the available options for this matter.

Hello Esteban
Thanks for asking. It's all clear, I will return the NUC 9 to the dealer JIB. It's just not that urgent because my old computer is still running fine. Then on Monday or Tuesday I drive into town and do it.
best regards
