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.

REPLACING A MICROPROCESSOR 5

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.

6 REPLACING A MICROPROCESSOR

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.

Figure 1-3

REPLACING A MICROPROCESSOR 7

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

8 REPLACING A MICROPROCESSOR

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.

REPLACING A MICROPROCESSOR 9

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.

10 REPLACING A MICROPROCESSOR

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).
