5 Set the microprocessor lightly in the socket and make sure all pins are
headed into the correct holes. Because your computer uses a ZIF
socket, there is no need to use force (which could bend the pins if the
microprocessor is misaligned). When the microprocessor is positioned
correctly, press it with minimal pressure to seat it.
6 When the microprocessor is fully seated in the socket, pivot the release
lever back toward the socket until it snaps into place, securing the
microprocessor.
Replacing the Heat Sink or Heat Sink/Blower Assembly
NOTICE: Ground yourself by touching an unpainted metal surface on the
back of the computer.
NOTICE: If you are installing a microprocessor replacement kit from Dell,
return the microprocessor to Dell in the same package in which your
replacement kit was sent.
NOTICE: If you are
not
installing a microprocessor upgrade kit from Dell,
reuse the original blower/heat sink assembly and securing clips when replacing
the microprocessor.
1
Remove the film covering the thermal grease on the bottom of the
heat sink.
2 On the small form-factor and small desktop computers, reinstall the
two screws that attach the blower to the heat sink.
3 Lower the heat sink or blower/heat sink assembly to the
microprocessor so that the heat sink fits in the retention base.
4 For each of the replacement metal clips, fit the end of the clip that
does not have the latch over its tab on the retention base. Then, fit the
middle of the clip over the middle tab on the retention base, and press
down on the clip’s latch to secure the clip to the retention base (see
the illustration for your computer in “Removing the Heat Sink or Heat
Sink/Blower Assembly”).
5 On the small mini-tower computer, lower the airflow shroud over the
heat sink.
6 Plug the fan cable into its connector on the system board.
7 Plug the 12-volt power cable into its connector on the system board.
8 Close the computer cover, reconnect your computer and devices to
their electrical outlets, and turn them on.
