Upgrading and Servicing Guide

Safety Information

This product has not been evaluated for connection to an “IT” power system (an AC
distribution system with no direct connection to the earth, according to IEC 60950).

The Upgrading and Servicing Guide provides instructions on how to remove and replace
hardware components of your PC.

Opening and Closing the PC

WARNING: Please read “Safety Information” in the Limited Warranty and
Support Guide before installing and connecting your system to the electrical
power system.

2 Upgrading and Servicing Guide

Preparing the PC

Before you upgrade any component in your PC, you need to prepare the PC so that you
can safely handle it and the components.

Read the following items before attempting to upgrade or service the PC:

1 These procedures assume familiarity with the general terminology associated with

personal computers and with the safety practices and regulatory compliance required
for using and modifying electronic equipment.

2 Write down and save the system model and serial numbers, all installed options, and

other information about the system. It’s easier to consult this information than to open
and examine the PC.

3 It is recommended that you use an antistatic wrist strap and a conductive foam pad

when working on the system.

Before Opening the PC

To avoid injury and equipment damage, always follow this procedure in this order before
opening the PC:

1 Remove any diskette, memory card, or optical disc (CD or DVD) from the PC.

2 Shut down the PC.

3 Disconnect the modem/telephone cable, if present.

4 Disconnect the power cord from the electrical outlet and then from the PC.

5 Disconnect all other attached cables (such as the keyboard, mouse, and monitor).

6 Disconnect all external devices.

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.

CAUTION: To reduce the risk of personal injury from electrical shock or hot
surfaces, disconnect the power cord from the wall outlet, and allow the
internal system components to cool before touching.

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.

Upgrading and Servicing Guide 3

After Closing the PC

To avoid injury and equipment damage, always follow this procedure in this order after
closing the PC:

1 Reconnect the power cord.

2 Reconnect the modem/telephone cable and all other cables (such as the keyboard,

mouse, and monitor).

3 Reconnect external devices.

4 Turn on the PC and all peripherals such as the monitor.

5 If you installed an add-in card, install any software drivers supplied by the card

manufacturer.

Removing the Side Panel

1 See “Before Opening the PC” on page 2.

2 Loosen the thumbscrew (A) that secures the side panel to the PC chassis. You may

need to use a screwdriver the first time you loosen the screw.

3 Use the handle to pull and slide the panel back about 1 inch (2.5 centimeters), and

then lift it off the chassis.

WARNING: To reduce the risk of electrical shock, fire, or damage to the
equipment, do not plug telecommunications or telephone connectors into the
network interface card (NIC) (labeled as an Ethernet connector).

WARNING: Beware of sharp edges inside the chassis.

4 Upgrading and Servicing Guide

Replacing the Side Panel

1 Align the tabs at the bottom of the side panel to the ridge on the bottom of the chassis.

Place the side panel in the proper position on the chassis and slide it toward the front
of the chassis.

2 Ensure that the hole for the thumbscrew aligns with the hole in the chassis, and then

replace the thumbscrew (A).

3 See “After Closing the PC” on page 3.

NOTE: There is a 3mm gap between the top of the side panel and the top of the

chassis when the side panel is attached properly.

Upgrading and Servicing Guide 5

Removing the Front Panel

card reader, an HP Pocket Media Drive bay, diskette drive, or the hard disk drive.

2 Swing the front panel away from the chassis toward the left to remove it.

Replacing the Front Panel

1 Align and insert the three hooks on the left side of the front panel with the holes on the

left side of the chassis.

2 Swing the front panel around and press the three hooks on the right side of the front

panel into the three holes on the right side of the chassis until the panel snaps into
place.
