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). WARNING: Before installing and connecting your system to the electrical power system, please read “Safety Information”...
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: 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.
After Closing the Computer To avoid injury and equipment damage, always complete the following steps in this order after closing the computer: Reconnect the power cord. 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).
Replacing the Side Panel Align 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. 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.
Replacing the Front Panel Align 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. Swing 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.
Locating Components Inside the Computer Upper 5.25-inch (13.34-centimeter) optical drive bay, which may be a CD-ROM, CD-RW, DVD-ROM, DVD+RW/+R, or combination drive Lower 5.25-inch (13.34-centimeter) optical drive bay, which may be empty (knockout plate), or a CD-ROM, CD-RW, DVD-ROM, DVD+RW/+R, combination drive, or HP Personal Media Drive bay (select models only) Primary hard disk drive Memory card reader (select models only)
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.
Disconnect 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.

Ensure 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. NOTE: The Serial ATA hard disk drive does not use Cable Select. Cable Select jumper Slide the optical drive partway into the front of the chassis.
Push the drive all the way in through the front of the chassis until it locks into place. Replace 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. NOTE: The following figure shows both optical drives.
Disconnect the power and data cables from the back of the drive. Pull the drive out through the front of the chassis. Adding or Replacing the Primary Hard Disk Drive If you are replacing the existing hard disk drive, remove it. See “Removing the Primary Hard Disk Drive”...

Connect the power and data cables to the back of the hard disk drive. A — Connect to a primary hard disk drive. B — Connect to a secondary hard disk drive (select models only). C — Connect to the motherboard. Slide the hard disk drive completely into the front of the chassis.
Removing the Memory Card Reader Prepare the computer to be opened, and then remove the side and front panels. See “Opening and Closing the Computer” on page 1. Release the memory card reader by removing the screw on the right side of the memory card reader, sliding the reader to the left to loosen it, and then pulling it partway out through the front of the chassis.
Adding or Replacing a Memory Card Reader If you are replacing an existing memory card reader, remove it. See “Removing the Memory Card Reader” on page 13. If necessary, remove the knockout plate on the front cover. To do this, press the release button (A), and then pull the plate out.
Push the memory card reader into the chassis until the screw hole on the chassis is aligned with the screw hole on the right side of the memory card reader, and then attach the screw to secure the memory card reader to the chassis. Replace the front and side panels, and then close the computer.
Align the new hard disk drive with the four screw holes on the front of the chassis, and then attach the four screws that secure the hard disk drive to the chassis. Make sure the data and power cables of the hard disk drive are facing the closed side panel and not towards the open side panel of the chassis.

Lift the hard disk drive out of the chassis, and then remove the hard disk drive cables. For most drive cables, use a gentle rocking motion to free the connector. For Serial ATA hard disk drive cables, press the latch (1) (select models only) in the center of each connector (2), and then pull the connector out of the drive connector.
Adding Memory Your computer comes with random access memory (RAM), which temporarily stores data and instructions on your computer. The computer is shipped with one or more memory modules, but you can replace the existing memory module(s) with higher-capacity modules. The motherboard contains sockets for DDR (double data rate) DIMMs (dual in-line memory modules).
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 memory socket. Always use the retaining clips to remove the module. Lift the memory module out of the memory socket.
Place the chassis upright. Replace the side panel, and then close the computer. See “Opening and Closing the Computer” on page 1. NOTE: If a blank screen is displayed after you replace or add a memory module, the module is installed incorrectly, or it is the wrong type of module. Remove and reinstall the memory module.

Gently lay the chassis on its side. Inside the computer, locate the add-in card slots on the motherboard. WARNING: Beware of the sharp edges on the add-in card slot cover. Move any cabling out of the way, if this is necessary to reach the add-in cards. Hold the card at each end, carefully rock it back and forth until the connectors pull free from the socket, and then lift the card from the chassis.
Installing an Add-in Card If necessary, remove the slot cover, or insert a flat-head screwdriver into the knockout plate slot (A), and then rotate the screwdriver to break the knockout plate. Align the edge of the add-in card with the add-in slot on the chassis and gently but firmly press the card straight down into the slot.
Replacing the Battery A lithium battery on the motherboard provides backup power for the computer timekeeping capability. The battery has an estimated life expectancy of seven years. When the battery starts to weaken, the date and time may become incorrect. If the battery fails, replace it with a CR2032 lithium battery (3 volt, 220mAH rating) or an equivalent battery.
