|[* black] Someone really did not want the battery in the MacBook Pro to come out of the upper case.|
|[* black] We tried valiantly with our [product|IF145-108|iFixit 6 Inch Metal Ruler] to free the battery from its aluminum confines, but to no avail. Rather than risk puncturing a lithium-polymer battery cell, we left the power source in place.
|[* black] To complicate matters further, the TrackPad cable lies underneath the battery. Attempting to pry the battery off the upper case could easily sever the fragile cable, which would be bad.
