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.

Upgrading and Servicing Guide 7
Removing and Replacing Drives
Your computer has several drives that you can replace or upgrade. See “Locating
Components Inside the Computer” on page 6 for the drive types and locations.
The hard disk drive is either a Serial ATA (advanced technology attachment) drive, which
uses a narrow data cable, or a Parallel ATA drive, which uses a wide data cable.
Select models have a second hard disk drive.
You can add an optical drive to an empty lower optical drive bay.
Removing an Optical Drive
1Prepare the computer to be opened, and then remove the side and front panels. See
“Opening and Closing the Computer” on page 1.
2Release the drive from the drive bay by removing the two screws on the side of the
optical drive, and then pulling the drive partway out of the front of the chassis.
CAUTION: Before you remove your hard disk drive, back up your personal
files 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 must run System Recovery using the recovery discs to load the
factory-installed files. For details about the recovery procedure, see the user
documentation that came with your computer.
IMPORTANT: Before you add a new optical drive, ensure that it is compatible with the
computer operating system. Also, ensure that you have the correct software and drivers for
the optical drive to work with the operating system.
NOTE: The following figure shows both optical drives. Your chassis may include one
or two optical drives, depending on your model.

8Upgrading and Servicing Guide
3Disconnect the power and data cables, and the sound cable from the back of the
optical drive you want to remove.
For most drive cables, use a gentle rocking motion to free the connector.
For Serial ATA hard disk drive cables, press the latch (select models only) in the
center of each connector and then pull the connector out of the drive connector.
4Pull the drive out through the front of the chassis.
Adding or Replacing an Optical Drive
1If you are replacing an existing drive, remove it. See “Removing an Optical Drive” on
page 7.
2If you are adding a drive to an empty lower optical drive bay, you must remove the
knockout plate from the bay. To do this, insert a flat-head screwdriver into the knockout
plate slot (A), and then rotate the screwdriver to break the knockout plate out of the
chassis. Discard the knockout plate.
3If necessary, remove the knockout plate from the front panel. To do this, insert a
flat-head screwdriver into the knockout plate slot (B), and then rotate the screwdriver
to break the knockout plate out of the front panel. Discard the knockout plate.

4Ensure that the jumper on the new optical drive or the new Parallel ATA hard disk
drive is in the CS (Cable Select) position. Your drive may vary from the illustration.
Cable Select jumper
5Slide the optical drive partway into the front of the chassis.
6Connect the power and data cables to the back of the drive you want to add.
Reconnect the sound cable, if it is present.
NOTE: The Serial ATA hard disk drive does not use Cable Select.
WARNING: If you are adding a second Parallel ATA drive, ensure that you
connect the data cable labeled Master to the primary hard disk drive, and the
data cable labeled Slave to the secondary hard disk drive. If the data cables
are not connected correctly, the computer will be unable to locate the hard disk
drives and data may be lost.

10 Upgrading and Servicing Guide
7Push the drive all the way in through the front of the chassis until it locks into place.
8Replace the two screws on the side of the optical drive into the holes labeled (1) on
the chassis to secure it to the drive bay.
