Hello WebMaximus, , it is possible to power up the D54250WYK using the Consumer Infrared (CIR).
We tested CIR using a TSGH-IR02 remote control on a D54250WYK NUC and CIR worked just fine on a Windows environment.
Please make sure you have installed the latest Infrared (CIR) driver https://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&DwnldID=23086&lang=eng
If you continue having this issue, it could be a compatibility problem between the NUC and the remote control.
Thanks Sylvia but if you read my initial post again you'll find that I'm already able to power the NUC ON just fine using my Logitech Harmony 900 remote, my problem is how to power the NUC OFF using the remote. When I send the same command 'Power Toggle' that I use to power it ON nothing happens.
Could it be a BIOS setting I need to change maybe...?
Which BIOS version do you have installed on your NUC?
I ran a file called WYLPT10H.86A.0026.EB.EXE which after a reboot said BIOS was successfully updated so I guess that means I'm running version 0026.
WebMaximus, as I explained you before this could be a compatibility problem with the remote control, even thought it power ON the NUC.
You can check if there is a firmware update available for the Logitech remote control.
I just test our remote control again on Windows 8 and it is working as expected.
I already posted about this over at Logitech but so far no comments.
Guess I'll just have to live with shutting the NUC down from inside Windows instead.
