I've already tried wiping it down to remove any finger prints that might have been on the buttons. I've also blow it out to clear any dust that might be causing overheating issues. but yet it still turns on and off by itself. oh! and the power supply works fine, it comes on when its suppose to and also shuts off when the machine shuts off. it goes from yellow to green and green to yellow when it suppose to. Are there any solutions for me?
