Two cables still connect to the logic board and must be removed before pulling the board entirely out of the computer.

Use a spudger to gently (very gently) pry up the left side of the logic board.

If the logic board does not immediately come free, it may be necessary to soften the thermal paste between the logic board and heat sink. You can soften the thermal compound using a hairdryer. Move the hairdryer back and forth between the two fans about one inch above the logic board for one minute. At this point, the logic board should now come free easily.
