Upgrading and Servicing Guide This guide provides instructions for upgrading the memory and the hard disk drive in your HP TouchSmart PC. 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).
It is recommended that you use an antistatic wrist strap and stand on a conductive foam pad when working on the computer. Hewlett-Packard recommends that you use a magnetic-tipped screwdriver when opening and closing the HP TouchSmart PC, to make it easier to remove and install the screws.

Opening the HP TouchSmart PC To avoid injury and equipment damage, always complete the following steps in order, when opening the HP TouchSmart PC: 1 Remove any media (CD, DVD, memory cards, USB devices, and external hard disk drives) from the HP TouchSmart PC. 2 Disconnect any external devices that are connected to the computer. CAUTION: Static electricity can damage the electronic components of the HP TouchSmart PC or optional equipment.
5 Remove the connector cover by inserting your finger under the gap on the bottom-left side of the cover (A), and then pulling gently. A 6 Disconnect all other attached cables from the back of the HP TouchSmart PC.
7 Place the computer face-down on a soft flat surface. HP recommends that you set down a blanket, towel, or other soft cloth (A) to protect the touch screen surface from scratches or other damage. 8 Apply additional pressure to lift the computer stand as far as it will go to an upright position, about 90 degrees (B) from the computer, and then move the latch to the left until it is in the locked position (C).
Remove the screw (A) that secures the memory cover to the back of the computer. A 11 Pull up the memory cover slightly on the bottom edge to release it (B), then, gently slide the cover down toward the bottom of the computer (C), and then remove it. B C WARNING: Beware of sharp edges inside the chassis. To upgrade your hard disk drive, see “Removing and Installing the Hard Disk Drive” on page 12.
Adding Memory Your HP TouchSmart PC comes with random access memory (RAM), which temporarily stores data and instructions on your computer. The HP TouchSmart PC ships with one or two memory modules that you can replace. Before you begin Observe the following requirements before removing and replacing the memory module. The motherboard contains sockets for SO-DIMMs (small outline dual in-line memory modules). A memory module with the key slot circled is shown in the following illustration.
Removing a memory module 1 Complete the procedures to prepare the HP TouchSmart PC. See “Opening the HP TouchSmart PC” on page 3. CAUTION: When handling a memory module, be careful not to touch any of the contacts. Doing so may damage the module. CAUTION: Do not pull the memory module out of the socket. Use the latches of the retaining clips to remove the module. 2 Push the two latches of the retaining clips away from the memory module. It may be easier to push one latch at a time.
3 Lift the memory module from the memory socket. Note the location of the key slot on the connector edge. 4 Store the memory module in antistatic packaging.
Installing a memory module Upgrade the memory in your HP TouchSmart PC with memory of the same type and speed as the memory originally installed. The capacity for both memory modules must match for optimal performance. Both memory modules can be installed by using the same procedure listed below. CAUTION: When handling a memory module, be careful not to touch any of the contacts. Doing so may damage the module. 1 Remove the memory module. See “Removing a memory module” on page 8.
3 Slide the memory module all the way into the memory slot, until the gold edge is almost completely hidden in the slot, and then push down the outer edge of the memory module until the retaining clips snap into place. CAUTION: The memory module must be inserted all the way into the slot before it is snapped down into place; otherwise it will not work properly. In the following illustration, a memory module is installed incorrectly (A), with the gold edge showing. A 4 Close the HP TouchSmart PC.
Removing and Installing the Hard Disk Drive You can replace or upgrade the hard disk drive. The hard disk drive is a Serial ATA (advanced technology attachment) drive, which uses a narrow data cable. CAUTION: Before removing the hard disk drive, back up any personal files on the hard disk drive to an external storage device, such as a DVD. Failure to do so may result in data loss. After replacing the hard disk drive, you need to run System Recovery using recovery discs to load the factory-installed files.
3 Remove the optical disc drive cover by lifting the bottom edge with your finger or a screwdriver, and then rotating the cover out and away from the computer. There are several tabs and two guide pins holding the cover in place, so be careful not to break the cover by applying too much force. 4 Make sure the wireless keyboard and mouse receiver (A) has been removed. See “Opening the HP TouchSmart PC” on page 3. Remove the nine screws that secure the back cover to the chassis.
5 Lift the back cover up from the bottom inside edge of the memory cover area to release it, place both hands under the bottom edge of the cover and lift it up, and then rotate the back cover up as far as it will go. 6 Lift away the back cover from the computer.
7 Remove the screw that secures the optical disc drive to the chassis, and then slide the drive toward the center of the computer to move it out of the way. You do not need to remove the optical drive cables. 8 Remove the screw that secures the hard disk drive cage to the chassis.
9 Slide the hard disk drive cage toward the top of the computer, and then pull it away from the computer. 10 Disconnect the power and data cables by pressing the latches and then removing them from the drive.
11 Remove the four screws that secure the hard disk drive to the cage, and then slide the hard disk drive out of the cage.
Installing a hard disk drive 1 If necessary, remove the hard disk drive. See “Removing the hard disk drive” on page 12. 2 Slide the hard disk drive into the cage, and then replace the four screws. 3 Connect the power and data cables to the hard disk drive.
4 Lower the hard disk drive cage straight down, align the four hooks on the cage with the four holes on the back of the chassis, and then slide the cage toward the bottom of the computer until it rests against the bracket on the chassis. 5 Replace the screw that secures the hard disk drive cage to the chassis.
6 Align the hooks on the optical disc drive with the holes on the computer, and then slide the optical disc drive toward the outer edge of the computer. 7 Replace the screw that secures the optical disc drive to the chassis.
8 Replace the back cover. Align the hooks at the top edge of the back cover with the holes on the top of the computer. The screw holes on the back cover should be aligned with the screw holes on the back of the computer. 9 Press the top, side, and then bottom edges to snap the cover into place.
10 Replace the nine screws that secure the back cover to the computer. Four of the screws are located along the bottom edge of the back cover, two are located on the sides of the optical drive, and three are located in the connector area. CAUTION: You must replace the screws on each side of the optical disc drive to ensure that the drive slot is aligned properly with the back cover.
Closing the HP TouchSmart PC To avoid injury and equipment damage, always complete the following steps in order, after closing the HP TouchSmart PC: 1 If you removed it, replace the computer stand.
