3. Rotate the CD-ROM drive cage up.
4. Disconnect any cables that impede access to the microprocessor.
5. Remove the fan-sink assembly from the microprocessor:
Note: The fan and underlying heat sink are attached and do not need to be
separated from each other. Remove the fan-sink assembly from the
microprocessor as a single unit.
a. Detach the fan-sink cable.
b. Loosen the two captive screws (in leaf-spring enclosures) on either side of
the fan-sink assembly.
c. With the two captive screws loosened, pivot the leaf spring assemblies
outward and out of the notches on the fan-sink assembly.
d. Lift the fan-sink assembly up and out of the computer.
Note: It might be necessary to gently twist the fan-sink assembly to loosen
it from the microprocessor.
Important: Be careful when handling the adhesive material on the
microprocessor. If the adhesive material on the microprocessor
will be reused, do not contaminate it. If replacement adhesive
material is provided with the replacement part, be sure to
remove all traces of existing adhesive material from the
microprocessor before applying the new adhesive material.
6. Free the microprocessor from the system board by rotating the microprocessor
socket lever arm upward to its maximum vertical position.
7. Lift the microprocessor up and out of the computer.
To install a microprocessor, reverse the previous steps.
