issue with 8th gen nuc


We have quite a few nucs (NUC8i7HNK) and from the 6/2018 and the 10/2018. We were setting up power on failure the device does what. We enabled the device will turn on after a power failure. WoL and a minor few.


If we unplug the device. Wait 15 or so seconds and plug it back in. The device behaves as normal.


If we unplug the device wait 2-3 seconds and plug it back in or flip the switch. The device does not power on. The power button on the front doesn't work. However if you unplug it from the back of the device and back in it will work.


We tried this on bios version 0034 and the latest. I suggested upgrading the the latest bios to a coworker who was working on this. Because I read in the release notes that it corrected the issue. Same issue across the board.


So the power button doesn't work. The bios settings are basic out of the box configuration with the exception of power on failure enabled. wake on hibernation, wake on shutdown (so s3,s4,s5)

Hello @CRein4​ 

You should update your NUC using Bios recovery method from Power Button Menu. The problem was fixed in Bios version 52. Now please update to version 54.

  1. Prepare USB stick fully formatted to FAT32 (disable quick format option during format). Format your USB in Windows machine (rather than Linux or MAC). Save the Bios file ( on this stick and insert it into front USB slot with amber color (NUC shall be OFF).
  2. Press Power Button for about 3 seconds. Count 1001, 1002, 1003,1004. Release the Power Button. NUC should reboot into Power Button Menu. You should release the Power Button before 4-sec shut down override.
  3. Press F4 and the recovery shall start (it can take up to 30 seconds for messages to appear on the screen).
  4. When the recovery finishes, press on Power Button and hold it, until NUC switches OFF. Pull out the power cord.
  5. Replace the power cord and press Power Button to switch the computer to ON.
  6. Enter Bios setting by pressing F2 during boot process.
  7. Press F9(followed by "Y"), to set Bios to default settings. Press F10 (followed by "Y"), to save the settings and exit to O.S. Let the NUC fully reboot.
  8. If before update, you have customized bios settings, you can enter again to Bios setting to change the necessary settings.
