Clip + turned off and I can't get it back on

I charged the clip overnight.  Was listening to it today when it just turned off.  I held the button down for 45 seconds, nothing.  It won’t even show on my computer when I plug it in.  I’ve only had it for a couple of months.  I didn’t drop it.  It didn’t fall in water.  It just stopped working.  I did reformat it recently because it wouldn’t let me delete anything,  That was on September 2.  What do I do next?

Is there a reason why it would turn off like that?  Like I said I had it in the charger overnight, listened to it this morning and then it just stopped.  Would the reformatting it have something to do with it?

This happened to my mp3 also and I tried your suggestion and it worked. Thanks

Thanks, I’ll be back if it doesn’t work.
