Step 28
Disconnect the DC-In connector from the left side of the logic board.
Step 29
Disconnect the battery cable from the front, left corner of the logic board.
Step 30
Grasp the logic board at the left edge with one hand and at the thinnest section with the other hand. Lift the left edge of the board up to approximately a 30 degree angle (if you don't have your protractor handy, just lift until the DVI port clears the right hinge).
Once the logic board clears the ports, slide it out to the left.
