Zip clip just stop dead and went blank

Hi, I have had this zip clip 6 months.  it was fully charged (last night).  listening to an audiobook when it just stoped. could not turn it on or off by buttom on top, did not show up at all when pluged into a computer to see what was happening.  I was sitting  with it on the arm of the couch when it just stoped, so I know it was not fall or get bumped.  Please advise if there is anything to be done with it or did it just die.

Thank you for any help.

Reset it. Press and hold the power button for 20-30 secs. Release, then press again momentarily to turn it on. It should start up normally.
