Lights on hades canyon stay on after windows shutdown

Hi,

The lights in my hades canyon stay on when the unit is shutdown. It has the latest drivers and bios, and the latest win 10 pro version. This is newly built 2 days ago.

Any ideas please?

Cheers

Bruce

  1. Enter Bios and press F9 followed by "Y". This will set Bios to default settings. Press F10 confirmed by "y" to save settings and exit to Windows.
  2. Uninstall The LED Manager (if installed) and check the shutdown now.

Yeah just tried that, still have blue power button, green power light and skull full on. It's almost as if there is no control on the skull, there wasn't with the led manager either.

1.Disconnect the Power cord.

2. Open the upper cover and lift the LED panel.

3. Disconnect the CMOS battery connector and reconnect it after 15 minutes.

4. Reassemble the upper cover, reconnect the Power cord and check the NUC.

  1. Did you make some changes?
  2. The Bios is still in default settings?
  3. Do you installed LED Manager? If not, install it and see the LEDs status.

If reset of the CMOS battery will fix this problem again, I would try to replace this battery. This is an example only: https://www.amazon.com/CR2032-Battery-51021-0200-B-1-25mm-Connector/dp/B07TS54R42/ref=sr_1_1?keyword...

I'll try that, but if the cmos battery is dead I would have thought I'd see the time and date errors on the post screen every time I booted up after I just pop the power out and leave it for 15 mins whilst keeping the batter in

Hi Bruce,

Theoretically you are right. The purpose of the CMOS battery in NUC is to keep RTC. That why after disconnecting this battery, you needed to set the date and time again. However, when the battery is not completely depleted, the time is still kept while we see some other phenomena is Bios functionality. In this forum I saw that is many cases, when the CMOS battery was weak, even the boot process was disturbed. This of course is not intended in design. This is some remains from the legacy bios taken to the new UEFI bios. In the nearest future, I hope, it will be fixed.

If you are still having issues with LEDs staying on after shutdown I have been testing some theories based on other research. Disable HDMI CEC feature in the BIOS and save and exit. Let me know if it solves your issue. I had same issue with a few other quirks but after doing the above my NUC has been flawless so far but time will tell.
