Procedure
1. Remove two screws and disconnect the cable.
2. Lift the modem from the connector on the logic board.
Warning: Whenever the bottom housing is opened for service, you must do two things:
1. You must clean the original thermal film from the surfaces joining the thermal
interface layer and reapply thermal paste to the thermal pipe.
2.You must tighten the four torx screws on the bottom housing to a minimum of
17
in.-lbs. If you do not have a torque driver, you will have to make sure these
screws are tightened by hand FIRMLY, BUT NOT FORCIBLY. Or, purchase the
service tool (076-0899) in order to ensure the thermal pipe is firmly
mated with the top base. If the bottom housing is not securely attached to the
base in this fashion, the CPU may overheat and become damaged.
Failure to
follow either of these steps could cause the computer to overheat and damage
internal components.
Refer to the topic, “Thermal Paste Application” for detailed information.
