Insert an opening tool near the middle of the logic board and pry up with a slow and steady force to peel it away from the frame.

Bending the logic board could lead to permanent damage. If the adhesive feels extra stubborn, apply more heat and try again.

Take care leveraging against the battery with the tool—a punctured or bent battery may leak dangerous chemicals or cause a fire.

If the logic board won't budge, slide an opening pick underneath the bottom edge of the logic board to slice some of the adhesive.
