Lift the logic board from its left edge and rotate it toward the right side of the lower case.
The logic board on this model has a tendency to get caught on the lower case near the DVI port at the upper right corner. If it catches as you are rotating it, stop to avoid bending and breaking the logic board.
Rotate the logic board until it is nearly vertical, and wiggle it around until it releases from the lower case.
When reinstalling your logic board, be sure to apply thermal paste to the CPU. Our thermal paste guide makes it easy.
Only replace the gray thermal paste on the CPU. The white thermal material on the GPU chips can be reused.
