Upgrading the Microprocessor
To replace the microprocessor, perform the following procedure.
1.
Remove the computer cover according to the instructions in "
Removing and Replacing the Computer Cover
."
2.
If you are working in the small-form-factor chassis or low-profile chassis, it may be helpful to remove the power supply.
If you are working in the mini tower chassis, it may be helpful to lay the computer on its side, and then rotate the power supply out of the way.
For instructions, see "
Rotating the Power Supply Away From the System Board (Mini Tower Chassis Only)
."
3.
If you are working in the mini tower chassis, remove the airflow shroud.
Pull up on the release tabs (see
Figure 1
) while you lift and rotate the bottom of the shroud up and away from the microprocessor/heat
sink assembly. Remove the shroud tabs from the chassis hooks, and lift the shroud out of the chassis.

4.
If you are working in the small-form-factor chassis or low-profile chassis, disconnect the cooling fan power cable from the system board
connector. Then remove the two thumbscrews securing the cooling fan to the heat sink. Lift the cooling fan from the microprocessor/heat sink
assembly.
