One thing sometimes suggested when there are problems like this after BIOS update is to go into the BIOS and find the feature to reset all parameters to defaults. Then put things back to the way you want them - one convenient thing to help point out what you may want to change is that there may be something like red asterisk (*) next to the items which were changed during reset to defaults.
If that does not help, someone reported here a month or so ago that their LED problem was solved by updating the BIOS a second time.
You can control Power Button and Ring led behavior with BIOS settings in following way:
3. Go to Advanced > Power.
4. In the Secondary Power Settings pane, you can:
- Change the Button LED brightness, blink/fade behavior, and color.
In order to use Power button LED to show the power status:
If you want your Power button LED to indicate Sleeping state set:
Of course, the above settings are my preference and you can choose from other options in Bios.
- Change the settings for Ring LED to show the HDD activity.
4. After making any changes to the LED settings, press F10 followed by "Y" to save and exit BIOS Setup.
Hope this will help
In my case the LEDs do not light up anymore - it doesn't matter what I set them up to. I tried reflashing the current BIOS as well as resetting everything to defaults without any success.
Just a thought: Did you, by any chance, recently have your NUC's chassis open? If so (or perhaps regardless), open it (again) and check to see whether the cable for the front panel is properly inserted in its connector on the board.
Hope this helps,
I hadn't it open a long while, but I checked that. There is no voltage on the circuit. Also the Power-LED is fixed at the board... there is no way to disconnect it. So the BIOS update bricked it somehow =/
I could bring back the Power-Button to life by setting it to "HDD-Activity" / "blue" / "0 - 50%". All other settings do not cause light coming outta there. Ring is still completely dead =(
You shall read carefully my post # 3. If you will follow what is written in this post it should work. You can use included translator to translate my post to language you can understand.
Now, since you have chosen the Power Button LED to to show HDD activity it will be lighted only when the HDD activity is detected.
In this case you can use the Ring Led to show the power status. In order to do it you need the Ring LED set to Power State Indicator.
And again, my post above describes the default settings (i.e. Power Button LED indicates Power State and the Rind Led indicates HDD activity). When you chose those settings you can control Power Led brightens and color in S0 and S3 state. However some user don't like the Ring Led showing HDD Activity, finding this LED in this function disturbing.
It is definetely not an issue with the connector, since I verified good connection using a ohmmeter at several spots.
All other settings in BIOS do not work for both LEDs... this points out there is definetely a software problem, because there is no other explanation for the Power LED.
Wow, after doing "Load Defaults" > "Recover BIOS" > remove all USB devices (except keyboard) > "Load Defaults" I got back the "HDD activity" and can assign it to both "Power Button" and "LED Ring". "Power Indicator" mode is still without function.
This is sick Oo
