Thank you for reaching out to us with your question. My apologies for the delayed response and for your wait. We’ve made some recent changes to the support team structure and some reports have experienced a longer response time than usual.
I’m sorry to hear that you were having issues with getting your Nucleus turned on. Since some time has passed I wanted to touch base to get your current status. If you’re still experiencing this problem and need assistance please let us know.
A few follow up questions for you:
Does the light for the power button light up at all?
Was there anything specific that occurred leading up to the Nucleus not working? Did you try a different power adapter or was there a power outage?
If you connect the Nucleus to a monitor via HDMI and power it up does anything display?
As well as a first step to try:
Please try the following with the device:
Unplug your Nucleus from the AC outlet and wait for about 15 minutes.
Press and hold the power button for ~30 sec a few times. Do this with no power source connected to make sure the Nucleus is discharged completely.
Connect the Nucleus to the AC outlet and try to turn it on.
Let me know if there is any change after this. We’ll be watching for your reply and get back in touch as quickly as we can. Thanks!
Thanks for the update! You can try a CMOS battery reset procedure, that has sometimes brought boards back to life, long shot but worth a try if you are comfortable with a more technical procedure. Instructions and video below:

That may help, and if not, we can replace the motherboard on our end for a fee, since the unit is no longer under warranty. Let me know!
I’m not able to comment on the cost at this moment but is something our accounts team will help with. Before looking to replace the motherboard, you do have the option to try a CMOS battery reset procedure.
Is this something you’ve already tried? Or, something you are not comfortable trying? Let me know and we can move forward with next steps!
CMOS Battery reset is the best bet as Ben says, the +5V standby is lit up on the board along with 12V rail. I had one with exactly the same symptoms last week, whipped the board out, disconnected the battery, re-seated the M.2 SSD and the Memory, left it overnight, reconnected and refitted the next day, all playing nicely and back from the dead. Very cheap, simple fix I wouldn’t start pricing up NUCs until you are 100% sure the one you have isn’t recoverable.
