This document provides instructions for replacing a microprocessor. To take advantage of
future options in speed and functionality, you can also upgrade the microprocessor in your
system.
NOTICE: Before you upgrade or replace a microprocessor, check the latest system BIOS
information on the Dell Support website at support.dell.com, and upgrade the BIOS if necessary.
The microprocessor and its associated cache memory are contained in a pin-grid array
(PGA) package that is installed in a ZIF socket on the system board. The following
subsection describes how to replace the microprocessor.
Replacing the Microprocessor
The following items are included in the microprocessor upgrade kit:
•
A microprocessor
•
A heat sink with cooling fan
CAUTION: See your System Information Guide for complete information about
safety precautions, working inside the computer, and protecting against
electrostatic discharge.
Turn off the system, including attached peripherals, and disconnect the system from
1
the electrical outlet.
Remove the cover (see "Removing the Cover" in your Installation and Troubleshooting
2
Guide).
Lay the system on its right side, as viewed from the front of the system.

CAUTION: The microprocessor and heat sink can become extremely hot. Be sure
the microprocessor has had sufficient time to cool before handling.
NOTICE: Do not operate the system without the heat sink installed. The heat sink is required to
maintain proper thermal conditions.
NOTICE: After removing the heat sink, place the heat sink upside down on a flat surface to
prevent the thermal interface material on the heat sink from being damaged or contaminated.
The microprocessor can overheat if the thermal interface is damaged.
NOTICE: The microprocessor fan and heat sink are constructed together as a single assembly.
Do not attempt to remove the fan from the heat sink.
