1 GB Clip Wont Boot Up

Hi, im new here but i want to first start off by saying this miniature mp3 playing device has been an excellent commodity for me. Ive been using it for over a year now and ive been impressed throughly. However, over the last two days ive been encountering a problem out of the blue which has lead me to believe i may have a defunct battery. Heres my situation:

I attempt to start the 1gb clip with the power slider on the left and it doesnt boot (start). I plug the usb cable into my computer and attach the Sansa Clip and it boots up with the standard “Connected” message at the top of the mp3 player with the battery bar charging. My question is, if my battery is being displayed as full when i plug it into the computer and when I try to start the Clip to no avail after i disconnect it from the PC, what is the issue?

Thanks, Marrow

Yes, ive also tried holding it for 15 sec… I cant get it to respond at all once its unplugged from the computer…

Update: After opening the clip up, i found that the battery was not connected to the positive connection, therefore its canned. I guess the battery was loose and tore the red wire out… Well thats that, ill just use my phone for my mp3 player now.
