It is designed to always be on to the point that cleaning it is becoming a pain. And it makes me wonder, who is controlling the machine, because it isn't designed to follow my instructions. If I want to clean the keyboard, I can't leave it on obviously because I'll just hit keys. If I shut it off, and clean the keyboard, the machine powers on without touching the power button every time. I'm so sick of this. Why can I just turn of the machine. I didn't ask it to power on.
