My keyboard RGB lighting is always on, even when the mini is asleep. I was thinking of trying Melatonin-Mac to see if it would help. I use a port hub on my Dell monitor and it's probably the monitor and not the mini. There is a USB option under Energy settings for the monitor but the option is greyed out. It's possible that it won't let me change the settings while the USB ports are in use. The mouse is also powered while sleeping as moving the mouse around wakes it up. I normally move the mouse around, the monitor comes on and I type in the password on the keyboard. My office environment is normally dark so I don't mind the light from the keyboard.
