My Sansa Clip Will Not Turn On

It is fully charged(when I plug it into my computer it says connected), but when I try turning it on it is unresponsive(nothing happens)…

Mine does the same thing. If you find out something, please let me know? My name is Tom… e-mail me at-

Same here.  Clip indicates that it is connected but doesn’t appear in “My Computer.”  It happens on two computers and worked just fine until recently.
