Microprocessor/Cooling Fan/Heat Sink Assembly
Figure 24. Microprocessor/Cooling Fan/Heat Sink Assembly
To replace a microprocessor, perform the following steps:
1. Remove the computer cover .
2. Disconnect the cooling fan power cable from its system board connector.
3. Remove the metal retaining clip that secures the heat sink assembly to the microprocessor package by gently pushing down on the folded
part of the retaining clip with a small screwdriver.
The retaining clip hooks over the sides of the zero insertion force (ZIF) socket.
4. Remove the heat sink assembly from the microprocessor package.
NOTICE: Be careful not to bend any of the pins when you remove the microprocessor package from the ZIF socket. Bending
the pins can permanently damage the microprocessor.
5. Detach and lift the microprocessor package away from the ZIF socket.
The ZIF socket has a lever-type handle that secures and releases the microprocessor package from the ZIF socket.
a. Pull the socket release lever straight out until the microprocessor package is released.
b. Remove the microprocessor package from the socket.
Leave the release lever extended so that the socket is ready for the new microprocessor.

CAUTION: The microprocessor/heat sink assembly can get extremely hot. Be sure that the assembly has had sufficient time to
cool before you touch it.
NOTE: Dell recommends that only a technically knowledgeable person perform this procedure.
