NUC8i7HVK BIOS - LED lights not working after update

[conboi]

Hi, 

Just wanted to share and see if anyone else is experiencing this issue after updating to the latest 0064 Bios update. After performing the update, the LED lights (power, all 3 status, and skull) no longer comes on. Checked the bios settings for the LED lights and made sure everything was enabled - no lights. Tried enabling software control using the LED manager and still nothing works!

Does anyone know what caused this issue? I'm assuming its the bios update because before that all the lights worked fine.

1. Follow instructions to update BIOS, using the BIOS Recovery Method from the Power Button Menu:
2. 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 HN0064.bio on this stick and insert it into front USB slot with amber color (NUC shall be OFF). You may use also one of the rear USB ports (do not use front blue USB port, since sometime the USB stick is not recognized during boot process). 
3. Press and hold 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 or when the Power Button LED changes color from blue to amber. 
4. Press F4 and the recovery shall start (it can take up to 30 seconds for messages to appear on the screen). 
5. When the recovery finishes, press on Power Button and hold it, until NUC switches OFF. Pull out the power cord. Remove the USB stick. 
6. Replace the power cord and press Power Button to switch the computer to ON. 
7. Enter Bios setting by pressing F2 during boot process. 
8. 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. 
9. If before update, you have customized bios settings, you can enter again to Bios setting to change the necessary settings.

My understanding is that there is the possibility of the LED programming being lost if the BIOS happens to contain updated firmware for the NUC's Embedded Controller. In this case, going into BIOS Setup (Visual BIOS) and making a change to the LED configuration (even a temporary one) will result in the programming being re-established.

Alternatively, if you are configuring the LED operation using the Intel LED Manager, simply starting the Intel LED Manager and reloading your saved configuration will result in the programming being re-established.

Hope this helps,

Exactly the same problem after updating to Bios 064, no LED’s working. Had to update via F7 as got error message when trying to update using Express Bio re unable to locate installation file.

Have tried all the following unsuccessfully:-
F4 BIOS recovery
Downgraded Bios to v063 (Pressing the Power Button did cause the Skull/Eyes to light up momentarily, but never again)
Temporarily changed settings in Bios
Tried turning off Software Control and using Bios to set control LED’s
Clearing CMOS with jumper

Nothing has resolved it

Same problem here:

• successfully updated to 0064 BIOS
• during the device restart, the skull flashed twice in deep red 

Now the LED lights are completely gone (no power, no status & no skull lights). I then

• set the BIOS to factory default settings: no effect
• disabled and re-enabled LED software control in BIOS: no effect
• uninstalled and reinstalled "LED manager for Intel": no effect

According to the "Intel Driver & Support Assistant" the system ist up to date. And so is MS Windows 10 (20H2).

Well my issue has gone from bad to worse.

Thought I’d try some other Bios settings this morning.

Saved and restarted “no bootable device”error. Went back in the Bios and sure enough no drives listed. Powered off, removed CMOS battery for a while. Reconnected, tried to restart and nothing. Just get a momentary white flash of the two LED’s next to the power button. Won’t power up at all! Tried a 2nd PSU I’ve got just in case.

Maybe in my case the LED issue was just a symptom of a greater issue, however it’s a strange coincidence

Just opened a new Support Case
