17.Important: If you have removed the logic board to access another part, and you will be placing the original logic board back in the computer, use a black stick to gently scrape away any residual thermal transfer material from the microprocessor chip on the logic board.
Warning: When scraping away the thermal transfer material from the microprocessor chip, be careful not to nick the microprocessor chip.
18.On the replacement logic board, center new thermal transfer material over the epoxy cap on the microprocessor chip. Press it into place.
Note: The thermal material pads break easily. Use care when removing the pad from its packaging and when handling, to avoid damage.
Important: If you are replacing the heat exchanger, verify that it has thermal material already installed on the mating surface to the microprocessor chip. If so, do not install thermal material to the chip on the logic board.
