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.
1
Turn off the system, including attached peripherals, and disconnect the system from
the electrical outlet.
2
Remove the cover (see "Removing the Cover" in your
Installation and Troubleshooting
Guide
).
3
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.
