I don't have a schedule or anything, sometimes it works its way into areas you don't touch often. Can't argue with results, I just wonder what would cause it that could be fixed with a reset unless it's just coincidence. Maybe slight static build up? My PS4 is on a strip which gets flipped off at night so it never has a chance to turn itself on.
Yeah, i got no idea either how it worked with a reset if it was dust that was causing the problem, but well thankfully it hasn't happened again.
