1 Pin-1 corners of chip and socket aligned
3. Set the microprocessor lightly in the socket, making sure that all pins are aligned with the correct holes.
Because the system uses a ZIF socket, there is no need to use force (which could bend the pins if the microprocessor is
misaligned).
4. When the microprocessor is positioned correctly, press it with minimal pressure to fully seat it in the ZIF socket.
5. When the microprocessor is fully seated, pivot the release lever back toward the system board until it snaps into place,
securing the microprocessor.
NOTICE: Ground yourself by touching an unpainted metal surface on the back of the computer.
6. Replace the fan/heat-sink assembly.
NOTICE: On the new heat sink, remove the plastic tab covering the thermal grease before placing the assembly on the
microprocessor.
a. Place the heat-sink assembly on top of the microprocessor.
b. Orient the metal retaining clip as shown in " Removing the Securing Clip ," and hook the unhinged end of the clip
over the tab on the top edge of the ZIF socket.
c. Rotate the lever upward until it snaps into place.
d. Replace the memory module that you removed in step 3 of the previous procedure.
NOTE: If you are installing a microprocessor replacement kit from Dell, return the original heat- sink assembly and
microprocessor to Dell in the same package in which your replacement kit was sent. Your microprocessor replacement
kit should include a replacement microprocessor heat sink. You need to reuse the original securing clip.
7. Reconnect the cooling fan power cable to the FAN connector on the system board.
8. As the system boots, it detects the presence of the new microprocessor and automatically changes the system
configuration information in system setup.
9. After you open and close the cover, the chassis intrusion detector causes the following message to be displayed at the
next system start- up:
