4 REPLACING A MICROPROCESSOR
Replacing a
Microprocessor
The Microprocessor
(sometimes called a
“processor”) inside your
computer performs
instructions and math
calculations. The more
powerful your micro-
processor, the faster certain
program tasks are
performed in multimedia
and communication
programs.
The microprocessor is usually
covered by a heatsink and
connects to an interface on the
System Board.
Introduction
Your Compaq Internet PC has an Easy Access panel that
makes accessing the internal parts easy. This document
describes how to remove and replace the microprocessor
(see Figure 1-1).
Figure 1-1
Important: The view shown may vary slightly by model.

Tools Needed
A Phillips screwdriver is needed to remove and replace the
microprocessor.
Warranty Statement
Compaq provides these detailed instructions to ensure your
safety and to keep your PC from being damaged. Following
these instructions also ensures that your PC remains
warranted by Compaq.
Your replacement part is warranted for the longer of 90 days
from the date the part was delivered to you, or the original
One Year Limited Warranty that came with your Compaq
Presario.
Preparing Your Computer for Disassembly
Before beginning the removal and replacement procedure,
complete the following procedure:
1. Remove any diskette or compact discs (CDs) from the
computer.
2. Turn off the computer and any peripheral devices
connected to your computer (see Figure 1-2).
3. Disconnect the power cord from the electrical outlet, and
then from the computer. (see Figure 1-3)
4. Disconnect all peripheral device cables from the computer.
Failure to disconnect the power from the computer may
result in personal injury.

I. Disconnecting the Power
1. Turn off the computer using the Power button (see Figure
1-2).
Figure 1-2
2. Disconnect the power cord from the electrical outlet 1
and computer 2(see Figure 1-3).
Failure to disconnect the power from the computer may
result in personal injury.

You do not have to replace the
screw securing the side access
panel. The screw securing the
side panel is used for shipping
purposes only.
II. Opening the Side Access Panel
1. Remove the screw 1securing the side access panel.
Locate the latch 2directly below the screw, press down,
and hold in the down position (see Figure 2-1).
Figure 2-1
Important: Some models may not have a screw 1. This screw is used for
shipping purposes only.
2. Grab the handle and slide the side panel from the chassis
(see Figure 2-2).
▲Caution: Before doing any work inside your computer, ground
yourself by touching a metal part of the chassis.
Figure 2-2

Look at the replacement part
carefully to help identify and
locate the component to be
replaced.
III. Locating the Microprocessor/Heatsink Assembly
See the illustration below for the location of the heatsink 1,
Microprocessor 2, microprocessor interface 3, and heatsink
power supply cable 4(see Figure 3-1).
Figure 3-1
Important: The location of the microprocessor/heatsink assembly may
vary slightly by model.

.
The heatsink cools the
microprocessor by displacing
heat. It sits on top of the
microprocessor. The heatsink
and microprocessor remove in
one piece. The heatsink can
either use a fan or can be a
non-powered heat dissipater.
If there is no fan located on
top of the microprocessor, you
have a non-powered heatsink,
and therefore do not need to
disconnect a power supply.
IV. Removing the Microprocessor/Heatsink
Assembly
To remove the Microprocessor/heatsink assembly, complete
the following procedure:
1. Turn the computer on its side (open side facing up) and
locate the microprocessor/heatsink assembly
(see Figure 4-1).
2. Disconnect the heatsink power supply cable
(see Figure 4-1).
Figure 4-1
The microprocessor may still be hot if the computer was
recently used. Allow the microprocessor to cool before
removing.

3. Disconnect the clip holding the heatsink and
microprocessor in place by pushing down 1on the tab and
pushing outward 2on the bottom portion of the tab to
release (see Figure 4-2).
