Default Power button behavior.
So was checking out task killer, "I know I know it's a very grey area. ". I set it to kill programs automatically when screen of. So I just assumed pressing the power button would actually do trick. However I noticed task killer wasn't actually killing anything as I had set it, so I then used spare parts and set the end behavior of the button to "sleep " and then task killer started working as I had set it. So my question is what does the sleep button do if you press it without spare parts.? Cause looking at my situation it definitely wasn't putting the phone to sleep as I assumed! It would.
