8.For each of the metal securing clips that secure the heat sink to the microprocessor, press down on the clip's latch to release the clip from the retention base. Then lift each clip out of the tabs on the retention base and away from the heat sink.

NOTICE: Gently rock the heat sink and then lift it to remove it.

9.Lift the heat sink away from the microprocessor.

NOTICE: Do not discard the original heat sink and securing clips unless you are installing a microprocessor upgrade kit from Dell. If you are not installing a microprocessor upgrade kit from Dell, reuse the original heat sink, blower, and securing clips when installing your new microprocessor.

10.Pull the socket lever up straight up until the microprocessor is released.

The microprocessor uses a ZIF socket with a lever-type handle that secures or releases the microprocessor.

NOTICE: Be careful not to bend any of the pins when you remove the microprocessor package from the ZIF socket. Bending the package pins can permanently damage the microprocessor.
