My volume rocker is stuck down, so the volume goes down to zero and stays there, and the little pop up thing in the upper left showing the volume is constantly there. Does anyone know if I can unstuck it somehow? I've noticed I can take at least part of the back off my surface, it would be nice if there's a way I can disable the volume rocker so it won't go back to zero if that's possible? I have a surface rt by the way. Thanks for any help!
