    • If necessary, use a spudger to pry up the left edge of the logic board to separate the solidified thermal paste from the heat sink.

    • If any resistance is felt when prying up on the logic board, we recommend softening the thermal paste by heating the board with a hair dryer before prying further.

    • 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.

    • Release the tabs on each side of the RAM chip at the same time. These tabs lock the chip in place and releasing them will cause the chip to "pop" up.

    • Pull the chip directly out from its connectors.

    • If there is a second RAM chip installed, pop it out in the same manner.

    • If you need to mount the logic board back into the heat sink, we have a thermal paste guide that makes replacing the thermal compound easy.
