general terminology associated with personal

computers, and with the safety practices and

regulatory compliance required for using and

modifying electronic equipment.

• Write down and save the system model and serial

numbers, all installed options, and other

information about the system. It will be easier to

consult this information than to open up and

examine the PC.

• Compaq recommends that you use an antistatic

wrist strap and a conductive foam pad when

working on the system.

WARNING: Always disconnect the modem

cord from the telephone system, and then

disconnect the PC from the power source

before removing the front and side panels

of the PC. Failure to do so before you

open the PC, or do any procedures, can

result in personal injury or equipment

damage.

before opening the pc

1 Remove any diskette or optical disc (CD or DVD)

from the PC.

2 Click the Start button, and then click Turn Off

Computer. Click Turn Off.

3 Disconnect the modem/telephone cable, if present.

CAUTION: To reduce the risk of personal

injury from electrical shock or hot

surfaces, disconnect the power cable

from the wall outlet, and allow the

internal system components to cool

before touching.

4 Disconnect the power cable from the electrical

outlet and then from the PC.

5 Disconnect all other attached cables (such as the

keyboard, mouse and monitor) and all external

devices.

CAUTION: Static electricity can damage

the electronic components of the PC or

optional equipment. Ensure that you are

discharged of static electricity by briefly

touching a grounded metal object.

2Upgrading and Servicing Guide

removing and replacing

drives

Your PC has several drives that you can replace or

upgrade. See the preceding topic, “locating

components inside the PC” for drive type and

location.

CAUTION: Back up your personal files on

the hard disk drive to an external

storage device, such as a CD, before

removing the hard disk drive. Failure to

do so will result in data loss. After

replacing the hard disk drive, you need

to run System Recovery, using the

recovery discs, to load the factory-

installed files. See the User’s Guide for

details about the recovery procedure.

You can add an optical drive into an empty lower

optical drive bay.

IMPORTANT: Before adding a new optical drive,

make sure that it is compatible with the Microsoft®

Windows®XP operating system. Also, make sure you

have the correct software and drivers for the optical

drive to work with the operating system.

removing a drive

1 Complete the procedures to prepare the PC, to

remove the side panel, and to remove the front

panel. See “opening and closing the pc” on

page 1.

adding memory

Your PC comes with random access memory (RAM),

which temporarily stores data and instructions on your

PC. The PC ships with one or more memory modules,

but you can replace the existing memory module(s)

with higher-capacity ones.

The motherboard contains sockets for DDR DIMMs

(double data rate dual in-line memory modules). The

exact number of sockets and type of DDR memory

module depends on which model PC you have.

ADDR DIMM

To determine which type of memory module your PC

uses, and for specific memory module information

and specifications, go to the Web site listed in your

Warranty and Support Guide and click the

Support link.

WARNING: Using the wrong type of

memory module could damage the

system.

removing a memory module

1 Complete the procedures to prepare the PC, and to

remove the side panel. See “opening and closing

the pc” on page 1.

2 Gently lay the PC on its side.

3 Locate the memory sockets on the motherboard.

CAUTION: When handling a memory

module, be careful not to touch any of

the contacts. Doing so may damage the

module.

4 Move any cabling out of the way, if necessary.

5 Push down the two retaining clips on the ends of

the memory socket until the memory module pops

out of the socket.

WARNING: Do not pull the memory

module out of the socket. Use the

retaining clips to eject the module.

6 Lift the memory module from the memory socket.

installing a memory module

Upgrade the memory in your PC with memory of the

same type and speed as the memory originally

installed in your PC.

CAUTION: When handling a memory

module, be careful not to touch any of

the contacts. Doing so may damage the

module.

1 Open both latches of the memory module socket.

• If you are replacing a memory module, put the

new memory module in the same memory slot

from which the old memory was removed.

• If you are adding a memory module, install the

new module into the socket nearest the

preinstalled module, and install additional

modules in the next available sockets.
