1. Turn off the computer and remove external cables.
2. Remove the side cover (see “Removing the side cover” on page 25).
3. Disconnect any cables that impede access to the microprocessor.
4. Remove the heat sink from the microprocessor:
a. Press the microprocessor-baffle release lever down, move it toward the
other microprocessor, and lift it up to the open position.
b. Slide the heat-sink assembly toward the front of the computer and tip the
rear flange out of the heat-sink socket.
c. Lift the heat sink up and out of the computer.
Note: It might be necessary to gently twist the heat sink to loosen it from
the microprocessor.
Important: Be careful when handling the microprocessor and heat sink. If
the thermal grease between the microprocessor and heat sink
will be reused, do not contaminate it. If replacement thermal
grease is provided with the replacement part, be sure to remove
all traces of existing thermal grease from the remaining part
before applying the new thermal grease.
