HVK - leds and lights not working

[SamRyan]

My HVK NUC recently started having issues with the leds, particularly the skull and the front lights.

After turning it on, no lights at all came on or were working. After 5 minutes, one light came on and stayed solid until I turned it off. Several restarts no fix. After a day, I turned it on and all lights back on and working.

Anyone else have this issue?

I have seen some strangeness as well. I go into the LED Manager and simply click to reload my configuration and voila! it's fixed.

Tried with mine.. unfortunately no luck... The LED manager has been busted for months, used to sit in the dock but now it wont auto start. Even tried redownloading to no luck. 

Unplugging power for 10 minutes helped.. but shouldn’t have to. Will keep an eye on it. Might reflash and restore bios 63

Hello SRyan10, 

Thank you for posting on the Intel® communities.   

There may be several reasons why the LED lights are not working, try the following steps: https://www.intel.com/content/www/us/en/support/articles/000029598/intel-nuc/intel-nuc-kits.html 

1. LED lights are disabled from Tray Application 

When the LED Manager for Intel® NUC is launched an icon will appear in the tray to allow quick control of the LEDs. The tray application will continue running even if the main UI application is closed. Selecting Disable All from the tray menu will turn off all of the LEDs on the NUC. To enable Lights, follow these steps:

1. Access the application. 
2. Select drop-down menu on each light section 
3. Turn it up 
4. Do the same with each light section 

2. LED cable inside the chassis is disconnected: 

Remove the six screws on top of the chassis, using the hex key that was included in the box, and remove the cover. 

Check the three cable connections on the top plate to be sure they are fully connected. 

Unscrew the small silver screw to release the top plate. 

Check the cable connection to the motherboard to be sure it is fully connected. 

Replace the plate and top cover, then test the LEDs again. 

3. Power issue, check if the same issue happens with a different power adapter or power outlet.  

4. Update the BIOS to the latest version available:
