Does Connected/Charging light up when you connect to the computer? If not, the cord may be bad. You can get a generic one at Amazon or from cell-phone companies for about $5. Look for USB cord or sync cable for the Fuze or for the E200, it’s the same cord. (Not the Fuze + Plus, which has a standard microUSB connector.)
If it does show charging and you leave it to charge for a long time, then disconnect and it goes dead, then the battery can’t hold a charge any more. That would make it R.I.P. A rechargeable battery eventually stops working.
