  • If these steps don't solve the problem, perform a BIOS Recovery.
LED is blinking See Blink Codes and Beep Codes for Intel NUC to identify patterns and solutions.
LED is OFF See if the board is getting power:
  1. Remove the bottom chassis cover to view the board inside.
  2. Plug in the AC adapter.
  3. If the internal power LED does not light up, try a different AC adapter.

Other troubleshooting tips

Memory issues
  • Use the correct voltage memory modules for your Intel NUC. To find the memory requirement for your Intel NUC, go to System Memory Information.
  • Remove and reinstall the memory modules to make sure they are fully seated in the sockets.
  • If you've installed two memory modules, try removing one of them.
  • If you've installed one memory module in an Intel NUC that has two memory slots, try moving it to the other memory slot.
  • A pattern of three LED blinks during boot can indicate defective memory. To isolate a specific module as defective, boot the system with just one installed at a time. You can also try testing suspected defective memory in a different system.
Overheating issues

The following symptoms can occur if installed components in the Intel NUC overheat:

  • Devices (such as mSATA SSDs) are no longer detected.
  • The system won't boot.
  • The system randomly shuts down.

If any of the overheating symptoms appear, check the following:

  • The Intel NUC is on a hard surface.
  • The ventilation holes in the back and bottom of the chassis aren't blocked.
  • The Intel NUC is set vertically on its left or right side (for better airflow to the bottom ventilation holes).

Monitor/display issues
  • If the Intel NUC is connected to the display through an AV receiver, or with a video adapter (such as HDMI*-to-DVI), try connecting directly to the display instead.
  • If the display has multiple video inputs, make sure you've selected the correct source (usually selectable via an input option on the display's remote control device).
Settings were changed in BIOS

Changes in BIOS settings (such as Fast Boot or performance settings) can cause the Intel NUC to no longer boot.

Restore BIOS defaults:

  1. Press F2 during boot to enter the BIOS Setup.
  2. Press F9 to load factory defaults.
  3. Press F10 to save and exit the BIOS Setup.
  4. If restoring BIOS defaults doesn't work, clear the CMOS.

You might need to perform a BIOS Recovery after clearing the CMOS. Recovery is possible even when there's no display on the computer.
