How do you make use of 'SW control' mode of Power Button LED on the NUC7i7DNBE?

I'm trying to make use of the software control mode of the Power Button LED on my NUC. I have found documentation/tools on controlling the LED but none of them are for my NUC model.

Does my NUC (NUC7i7DNBE) definitely support the SW control mode?

 

I'm on the latest bios version (DNKBLi7v.86A at the time of writing)

Russell, Thank you for posting in the Intel® Communities Support. I looked in the TPS (Technical Product Specification) of the Intel® NUC Board NUC7i7DNBE and I did not found any information in reference to the software control mode: https://www.intel.com/content/dam/support/us/en/documents/mini-pcs/nuc-kits/NUC7i7DN_TechProdSpec.pd... I also looked in our web site for an application that might be related to what you are looking for nothing showed up: https://downloadcenter.intel.com/product/130394/Intel-NUC-Board-NUC7i7DNBE The software control mode, is that an application? Could you please provide a description of what do you mean by that? Which Windows version are you using? Regards, Alberto R. Intel Customer Support Technician Under Contract to Intel Corporation

Hi Alberto, thanks for the response.

 

By software control mode, I'm referring to the option in the BIOS for the Button LED which allows you to control the NUCs power button's LED state (on/off/flash/dual color) dynamically from software.

The BIOS option is under Power -> Button LED where the value can be set to "SW control"

https://www.intel.com/content/dam/support/us/en/images/boardsandkits/nuc-kits/button-led.jpg

 

There is an article here describing the programmable Button LED, although it refers to NUC7i[x]BN and not my board (NUC7i7DNBE)

https://www.intel.co.uk/content/www/uk/en/support/articles/000023426/mini-pcs/intel-nuc-kits.html

 

This option is present in the BIOS for my board and the BIOS settings glossary here:

https://www.intel.com/content/dam/support/us/en/documents/mini-pcs/BIOSGlossary_NUC.pdf

 

I'm trying to use this feature although none of the documentation refers to my specific board model so I'm wondering if it definitely supports it (even though the option is present in the bios)

 

I'm running both Ubuntu and Windows 10.

 

Thanks

Hi Russell, Thank you very much for clarifying that information. When Software Control is enabled, the Power Button LED is controlled by Windows Management Instrumentation (WMI) Explorer*. https://www.intel.com/content/www/us/en/support/articles/000023426/mini-pcs/intel-nuc-kits.html?wapk... In the following link you will be able to confirm that and the rest of the LED settings and details: https://www.intel.com/content/www/us/en/support/articles/000023554/mini-pcs/intel-nuc-mini-pcs.html Regards, Alberto R.

Hi Alberto,

I'm still not sure if my product supports this feature as the second link you posted at the bottom says:

"This article applies to 15 products."

 

And none of the models listed include my model - NUC7i7DNBE

 

There is a Ubuntu Linux module for changing the LED state from the command line which doesn't work for me, although I appreciate Ubuntu is not an officially supported OS.

 

I thought I would investigate at least if my board is actually suppose to support software controlled LED state - Is it possible to verify whether or not this board should support the software controlled LED state?

 

Thanks

Russell

Hi Ronny Thanks for the information. Would that mean its a bug that the option 'SW Control' is selectable in the bios? Thanks Russell

Hi Russell, My apologies for the delay in getting back to you, this type of issues are difficult to fix or address. I dont have a thorough understanding of the way we are going to fix this but I am guessing it would imply removal of some options in BIOS and updates to the website. This is not really a "bug" in BIOS but it is more of an option not supported that we need to remove. I apologize again for the trouble we created with that. Regards, Ronny G
