Procedure
1. Remove the two blind mate screws. Replacement Note: The tab on the blind mate
connector faces inward.
2. Lift the blind mate connector off the chassis. Note: The blind mate connector is part of
the neck assembly.
Replacement Notes:
Blind Mate Connector: Make sure to replace the blind mate connector into the chassis
with the tab facing inward (toward the fan). And, when tightening the screws, the blind
mate connector should have some play; do not tighten down so it doesn’t move at all.
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.
