Not recognized/won't charge

I’ve read over all the threads over and over.  I’ve tried to change modes, but there just isn’t enough of a charge for this thing to stay on.  It says battery too low and shuts off.  I can plug in my wife’s and it works no problem.  Am I dead in the water here?  I’ve been troubleshooting and reading for 2 days and I’m about to just chuck it and buy an iPod.  Any one out there know how to fix this?

I’ve tried that as well, I think I’m going to get the Sansa E200 4Gb and see how that works.  I’ll be checking here to see if there’s anything I can do or check the warranty again.  Thanks for the help
