Clip doesnt work while disconnected from computer

My Clip just stopped working after i plugged it off from the computer… i cant turn it on otherwise its working if i plug it into the comp:/ anyone suggestions?

thanx

Perhaps a dead battery/a battery with disconnected leads?  I’d reformat the Clip/re-apply the firmware (it can become corrupted); if there’s still an issue, I’d call SanDisk for a warranty replacement.
