I've been using the external IR to control the cable box and receiver. When I want to turn them on or off I press FN and the power button. No problems. This doesn't turn off the TV so I usually get up and do this manually. Last night I forgot to press FN and hit the power button. The TV turned off. How? I couldn't believe it. Tried turning it on and off 4-5 times and it worked great. I can now be a little more lazy and not walk all the way to the TV. But I am still using too much energy in my fingers. Is there a way I can have all 3 turn on/off with one button?
