4 Removal and replacement procedures preliminary requirements Tools required You will need the following tools to complete the removal and replacement procedures: ● Phillips P0 screwdriver ● Torx T8 screwdriver ● Non-marking plastic pry tool 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 This chapter provides removal and replacement procedures for Customer Self-Repair parts. NOTE: 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.

used to perform system recovery if the hard drive becomes corrupted. System recovery reinstalls the original operating system and software programs that were installed at the factory and then configures the settings for the programs. HP Recovery media can also be used to customize the system or restore the factory image if you replace the hard drive. – Only one set of recovery media can be created. Handle these recovery tools carefully, and keep them in a safe place.
Using the HP Cloud Recovery Download Tool (select products only) To create HP Recovery media using the HP Cloud Recovery Download Tool: 1. Go to http://www.hp.com/support. 2. Select Software and Drivers, and then follow the on-screen instructions. Restore and recovery There are several options for recovering your system. Choose the method that best matches your situation and level of expertise: IMPORTANT: ● Not all methods are available on all products.
IMPORTANT: Recovery through HP Recovery Manager should be used as a final attempt to correct computer issues. ● HP Recovery media must be used if the computer hard drive fails. If you have not already created recovery media, see Using HP Recovery media (select products only) on page 90. ● To use the Factory Reset option (select products only), you must use HP Recovery media. If you have not already created recovery media, see Using HP Recovery media (select products only) on page 90.
Using HP Recovery media to recover You can use HP Recovery media to recover the original system. This method can be used if your system does not have an HP Recovery partition or if the hard drive is not working properly. 1. If possible, back up all personal files. 2. Insert the HP Recovery media, and then restart the computer. NOTE: If the computer does not automatically restart in HP Recovery Manager, change the computer boot order. See Changing the computer boot order on page 94. 3.
