I have mid-2007 white MacBook and while swapping out the HDD, I put the battery back in with the HDD still out. Now when I turn the locking dial to unlock the battery to remove it, it no longer unlocks and won't come out!!! When I turn the dial to lock/unlock the battery, I hear a click, but nothing happens... I tried taking the MacBook apart, however I need to remove a few screws from inside the battery bay so that the shell comes off. So I'm at a stand still. Any ideas? Thanks!
