I have a Sansa Fuze MP3/MP4 player, 8 GB with a expandable slot for more memory. I have had it for about 2 to 3 weeks and it was player just fine then all of a sudden it just up and quit. The light around the wheel stayed on but then it wouldn't do nothing else. It wouldn't charge, it wouldn't recognize it when I would plug it in on the computer. Then all of a sudden it went off and then I could play it until the battery went completely dead. Then, It wouldn't do nothing again, then, all of a sudden it would show it is charging and it would recognize it on the computer then as well. Does anybody have any idea what could have happened.
