I took my 2007 macbook to the Apple Store because the latch on the battery case won't release. The tech there could not get the battery to release either and recommended turning the laptop into a desktop or finding a case that can be charged. (like a portable docking station) I have been searching the web and can't find one. He mentioned it was a feather case from incipio - but the ones I have found do not charge. Does this make sense to anybody?
