Upgrading and Servicing Guide 1
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).
This Upgrading and Servicing Guide provides instructions for removing and replacing
hardware components of your computer.
Opening and Closing the Computer
WARNING: Before installing and connecting your system to the electrical
power system, please read “Safety Information” in the Limited Warranty and
Support Guide.

2Upgrading and Servicing Guide
Preparing the Computer
Before you can upgrade any component in your computer, you must prepare the computer
so that you can safely handle it and the components.
Before attempting to upgrade or service the computer, read the following items:
1These 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.
2Write down and save the computer model and serial numbers, all installed options,
and other information about the computer. It is easier to consult this information than
to open and examine the computer.
3It is recommended that you use an antistatic wrist strap and a conductive foam pad
when working on the computer.
Before Opening the Computer
To avoid injury and equipment damage, always complete the following steps in this order,
before opening the computer:
1Remove any device, memory card, or optical disc (CD or DVD) from the computer.
2Shut down the computer.
3Disconnect the modem/telephone cable, if it is present.
4Disconnect the power cord from the electrical outlet and then from the computer.
5Disconnect all other attached cables (such as the keyboard, mouse, and monitor
cables).
6Disconnect all external devices.
WARNING: Before removing the front and side panels of the computer, always
disconnect the modem cord from the telephone system, and then disconnect
the computer from the power source. Failure to do so 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 electrical outlet, and allow the
internal system components to cool before touching them.
CAUTION: Static electricity can damage the electronic components of the
computer 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 Computer
To avoid injury and equipment damage, always complete the following steps in this order
after closing the computer:
1Reconnect the power cord.
2Reconnect the modem/telephone cable and all other cables (such as the keyboard,
mouse, and monitor cables).
3Reconnect the external devices.
4Turn on the computer and all peripherals (such as the monitor).
5If you installed an add-in card, install any software drivers supplied by the card
manufacturer.
Removing the Side Panel
1See “Before Opening the Computer” on page 2.
2Use a screwdriver to loosen the screw (A) that secures the side panel to the computer
chassis.
3Use the handle to slide the panel back about 2.5 centimeters (1 inch), 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 cables into the
network interface card (NIC) (labeled as an Ethernet connector).
WARNING: Beware of sharp edges inside the chassis.

4Upgrading and Servicing Guide
Replacing the Side Panel
1Align the tabs at the bottom of the side panel with the ridge on the bottom of the
chassis. Place the side panel in the proper position on the chassis, and then slide it
toward the front of the chassis.
2Ensure that the hole for the screw is aligned with the hole in the chassis, and then
replace the screw (A).
3See “After Closing the Computer” on page 3.
Removing the Front Panel
This procedure is necessary only when you are removing or replacing an optical drive,
memory card reader, HP Media Drive bay, or the primary and secondary hard disk drives.
1Pull the three tabs away from the outside edge of the chassis.
2Swing the front panel (to the left) away from the chassis to remove it.
NOTE: There is a 3 millimeter 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
Replacing the Front Panel
1Align the three hooks on the left side of the front panel with the holes on the left side of
the chassis, and then insert them.
2Swing the front panel to the right (toward the chassis), and then 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.
