If any of the pins on the microprocessor appears to be bent, see "Contacting Dell" in your Owner's Manual for instructions on obtaining technical assistance.
2.Align the
HINT: You must identify the
NOTICE: You must position the microprocessor correctly in the socket to avoid permanent damage to the microprocessor and the computer when you turn on the computer.
3.If the release lever on the socket is not fully extended, move it to that position now.
4.With the
NOTICE: When you place the microprocessor in the socket, ensure that all of the pins go into the corresponding holes on all sides of the socket. Be careful not to bend the pins.
5.Set the microprocessor lightly in the socket and ensure that 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.
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.
7.Remove the film covering the thermal material on the bottom of the heat sink.
8.Lower the heat sink to the microprocessor so that the heat sink fits in the retention base.
9.For each of the replacement securing clips, fit the end of the clip that does not have the latch over the tab on the retention base. Then, press down on the clip's latch to secure the clip to the retention base (see the figure).
10.Lower the
11.Replace the computer cover.
NOTICE: To connect a network cable, first plug the cable into the network wall jack and then plug it into the computer.
12.Connect your computer and devices to electrical outlets, and turn them on.
If you are installing a microprocessor replacement kit from Dell, return the original heat sink assembly and microprocessor package to Dell in the same package in which your replacement kit was sent. Your microprocessor replacement kit should include a replacement microprocessor heat sink and one replacement securing clip.

CAUTION: Before you begin any of the procedures in this section, follow the safety instructions provided in your Owner's Manual.
CAUTION: To guard against electrical shock, always unplug your computer from the electrical outlet before opening the cover.
