4 Removal and replacement procedures Preliminary replacement requirements Tools required The following tools are needed to complete the removal and replacement procedures: ● Flat-bladed screwdriver ● Magnetic screwdriver ● Phillips P0 and P1 screwdrivers Service considerations Before disassembly or assembly procedures, review and adhere to all service considerations.
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.
Component replacement procedures This chapter provides removal and replacement procedures. There are as many as 75 screws, in 12 different sizes, that must be removed, replaced, or loosened when servicing the computer. Make special note of each screw size and location during removal and replacement.

7 Backup and recovery Recovery after a system failure is as complete as your most current backup. HP recommends creating recovery discs immediately after software setup. As you add new software and data files, continue to back up your system on a regular basis to maintain a reasonably current backup.
Depending on the computer model, you might have one of the following backup and recovery solutions: ● Roxio BackOnTrack ● HP Recovery Manager NOTE: For detailed information, perform a search for these topics in Help and Support. Creating recovery discs HP recommends creating recovery discs to be sure that you can restore your system to its original factory state if you experience serious system failure or instability. Create these discs after setting up the computer for the first time.
Backing up your information As you add new software and data files, back up the system on a regular basis to maintain a reasonably current backup. Back up your system at the following times: ● At regularly scheduled times NOTE: Set reminders to back up your information periodically.
Using Windows Backup and Restore To create a backup using Windows Backup and Restore: NOTE: Be sure that the computer is connected to AC power before starting the backup process. NOTE: The backup process might 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 and create a backup.
Using system restore points When backing up the system, you are creating a system restore point. A system restore point allows you to save and name a snapshot of your hard drive at a specific point in time. You can then recover back to that point if you want to reverse subsequent changes made to the system. NOTE: Recovering to an earlier restore point does not affect data files saved or e-mails created since the last restore point.
NOTE: Windows has its own built-in repair features, such as System Restore and driver roll-back capabilities. Try these features before using Recovery Manager. NOTE: Recovery Manager recovers only software that was preinstalled at the factory. Software not provided with this computer must be downloaded from the manufacturer's Website or reinstalled from the disc provided by the manufacturer. Recovering from the recovery discs To restore the system from the recovery discs: 1. Back up all personal files.
Linux backup and recovery Use the instructions in this section if SUSE Linux SLED 11 is installed on the computer. To protect your information, back up your files and folders. Then if the system fails, restore your important files from copies. Use the options listed in this section to restore the operating system and programs that were installed at the factory. CAUTION: Using f11 completely erases hard drive contents and reformats the hard drive.
