Sansa Just Stopped Working

I got some great responces to a request a month or so ago about my new Sansa not playing through my car’s USB plug in; problem solved after some great tips from you all.  New problem…the darn thing died!  or apparently died!  I got nothin.  was playing one day, next day stopped, totally.  doesn’t even show up when I USB it to my computer, doesn’t seem to be getting a charge.  Only bught it back in May.  Is there a reset or something?  Odd to think that it just died!

TIA

Thanks. Yes I read that in another thread after posting my question. It is working now after holding the power button for 15-20 seconds. Have had it connected to my PC for several hours but not sure if it is charged. Just disconnected and turned it off and will check in the morning. I just bought it at Radio Shack this Spring so I’m not sure if it’s a clip or clip plus. It’s black and holds 4 gigs.
