Step 20

Important! When you reinstall a logic board, you’ll need to replace the thermal paste that goes between the processor on the logic board and the heat sink. Failure to remove the old paste and apply a new layer can cause the computer to overheat and sustain damage. The following steps refer to replacing the thermal paste between the processor and heat sink; follow these steps only when you are ready to place the logic board in the computer.
Use a firm plastic edge to scrape the thermal material off the heat sink.
Apply a new layer of thermal paste to the heat sink.
The PC Card cage needs to be removed before installing your new logic board. The modem cable runs from the modem to the logic board, but connects to the modem underneath the PC Card Cage. After removing the PC card cage, you will need to disconnect the modem cable from the modem, plug it into the bottom of the logic board, and then plug it back into the modem. The PC Card cage can then be reinstalled by following the instructions backwards.
