My clip + is fully charged and playing music. I am unable to turn the unit off at all. I have pressed and held the top button for 20 seconds. The unit go into sleep mode. When I touch any other button it lights up and shows me the song playing. I also added the latest firmware, at which point it updated and then shut down completely. I tried to turn on and it would not power up. I plugged into my usb at which point it started charging. I unplugged the unit and now it will not turn off again.
Any thoughts?
