@jason, I noticed over the weekend that things weren't 100%. When applying the profile you gave it seemed to work because I had every device that was listed in...
powercfg -devicequery wake_armed
...and then disabled it via...
powercfg -devicedisablewake '$DeviceName'
...so when I applied your fix, the keyboard was disabled from waking, so it didn't wake the PC.
However, after enabling it with...
Enable-WakeForDevice -DeviceName $deviceName
...The remote is waking the PC again through the Flirc when it is sleeping. I confirmed the only device listed as wake_armed is my logitech keyboard that is connected via the unifying USB receiver.
Any suggestions on how to only have my logitech keyboard wake the PC?
