Hi, I am unable to control the led lights via the LED manager application - the LED colours are not updated in real time as changes are made in the application. BIOS confirms that the LEDs are software controlled. Thank you, Faraz

Hi Faraz,

  1. In this case I can suggest to you two things: first, try to update your Bios using Bios Recovery Method from Power Button Menu and if this will not help you may issue request RMA in order to replace your NUC, since it is covered by warranty.
  2. Follow the next steps to perform Bios recovery:
  3. Prepare USB stick fully formatted to FAT32 (disable quick format option during format). Format your USB on Windows machine (rather than Linux or MAC). Save the Bios file HN0058.bio (https://downloadcenter.intel.com/download/28953/BIOS-Update-HNKBLi70-86A-?product=126143) on this stick and insert it into front USB slot with amber color (NUC shall be OFF).
  4. 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.
  5. Press F4 and the recovery shall start (it can take up to 30 seconds for messages to appear on the screen).
  6. When the recovery finishes, press on Power Button and hold it, until NUC switches OFF. Pull out the power cord. Remove the USB stick.
  7. Replace the power cord and press Power Button to switch the computer to ON.
  8. Enter Bios setting by pressing F2 during boot process.
  9. 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.
  10. If before update, you have customized bios settings, you can enter again to Bios setting to change the necessary settings.

Hello Faraz,

  1. Your settings in BIOS are correct for control LEDs color using LED Manager.
  2. Attached pleas find a video showing an example from my NUC8i7HVK. In this example I'm changing color of Power Button LED from blue to yellow. This change will have effect only in S0 state. If you want change color for S3 state, you need to chose S3 flap in LED Manager first.

Hey Leon, Thank you for the video. I did exactly what you did in the video. Changes were seen on monitor but not on the processor.

Hi Faraz,

I understand that you have successfully recovered your Bios. Is the LED Manager is working now correctly?
