4 Removal and replacement procedures preliminary requirements Tools required You will need the following tools to complete the removal and replacement procedures: ● Flat-bladed screwdriver ● Phillips P0 and P1 screwdrivers ● Torx T8 screwdriver Service considerations The following sections include some of the considerations that you must keep in mind during disassembly and assembly procedures.
Cables and connectors CAUTION: When servicing the computer, be sure that cables are placed in their proper locations during the reassembly process. Improper cable placement can damage the computer. Cables must be handled with extreme care to avoid damage. Apply only the tension required to unseat or seat the cables during removal and insertion. Handle cables by the connector whenever possible. In all cases, avoid bending, twisting, or tearing cables.
Grounding guidelines Electrostatic discharge damage Electronic components are sensitive to electrostatic discharge (ESD). Circuitry design and structure determine the degree of sensitivity. Networks built into many integrated circuits provide some protection, but in many cases, ESD contains enough power to alter device parameters or melt silicon junctions. A discharge of static electricity from a finger or other conductor can destroy static-sensitive devices or microcircuitry.
Packaging and transporting guidelines Follow these grounding guidelines when packaging and transporting equipment: ● To avoid hand contact, transport products in static-safe tubes, bags, or boxes. ● Protect ESD-sensitive parts and assemblies with conductive or approved containers or packaging. ● Keep ESD-sensitive parts in their containers until the parts arrive at static-free workstations. ● Place items on a grounded surface before removing items from their containers.
Equipment guidelines Grounding equipment must include either a wrist strap or a foot strap at a grounded workstation. ● When seated, wear a wrist strap connected to a grounded system. Wrist straps are flexible straps with a minimum of one megohm ±10% resistance in the ground cords. To provide proper ground, wear a strap snugly against the skin at all times. On grounded mats with banana-plug connectors, use alligator clips to connect a wrist strap.
5 Removal and replacement procedures for Customer Self-Repair parts CAUTION: The Customer Self-Repair program is not available in all locations. Installing a part not supported by the Customer Self-Repair program may void your warranty. Check your warranty to determine if Customer Self-Repair is supported in your location.

applications if the hard drive becomes corrupted. HP Recovery Disc Creator can create two kinds of recovery DVDs: ● Windows 7 operating system DVD—Installs the operating system without additional drivers or applications. ● Driver Recovery DVD—Installs specific drivers and applications only, in the same way that the HP Software Setup utility installs drivers and applications. Creating recovery media NOTE: The Windows 7 operating system DVD can be created only once.
To create a backup using Windows Backup and Restore: NOTE: The backup process may take over an hour, depending on file size and the speed of the computer. 1. Select Start > All Programs > Maintenance > Backup and Restore. 2. Follow the on-screen instructions to set up your backup, create a system image (select models only), or create system repair media (select models only).

In case of system failure, you can use the backup files to restore the contents of your computer.
CAUTION: Some Startup Repair options will completely erase and reformat the hard drive. All files you have created and any software installed on the computer are permanently removed. When reformatting is complete, the recovery process restores the operating system, as well as the drivers, software, and utilities from the backup used for recovery. 1. If possible, back up all personal files. 2. If possible, check for the presence of the Recovery Image partition and the Windows partition.
Using Windows operating system media (purchased separately) To order a Windows operating system DVD, contact support. See the Worldwide Telephone Numbers booklet included with the computer. You can also find contact information from the HP website. Go to http://www.hp.com/support, select your country or region, and follow the on-screen instructions. CAUTION: Using a Windows operating system media completely erases hard drive contents and reformats the hard drive.
