When servicing the computer:

As you remove each subassembly from the computer, place the subassembly (and all accompanying screws) away from the work area to prevent damage.

Using excessive force during disassembly and reassembly can damage plastic parts. Use care when handling the plastic parts. Apply pressure only at the points designated in the maintenance instructions.

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. Ensure that cables are routed in such a way that they cannot be caught or snagged by parts being removed or replaced. Handle flex cables with extreme care; these cables tear easily.

Removable drives are fragile components that must be handled with care. To prevent damage to the computer, damage to a removable drive, or loss of information, observe the following precautions:

• Before removing or inserting a hard drive, shut down the computer. If you are unsure whether the computer is off or in hibernation, turn the computer on, and then shut it down through the operating system.

• Before removing a diskette drive or optical drive, ensure that a diskette or disc is not in the drive and ensure that the optical drive tray is closed.

• Before handling a drive, ensure that you are discharged of static electricity. While handling a drive, avoid touching the connector.

• Handle drives on surfaces covered with at least one inch of shock-proof foam.

• Avoid dropping drives from any height onto any surface.

• After removing a hard drive, an optical drive, or a diskette drive, place it in a static-proof bag.

• Avoid exposing a hard drive to products that have magnetic fields, such as monitors or speakers.

• Avoid exposing a drive to temperature extremes or liquids.

• If a drive must be mailed, place the drive in a bubble pack mailer or other suitable form of protective packaging and label the package “FRAGILE: Handle With Care.”

Many 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, the discharge contains enough power to alter device parameters or melt silicon junctions.

A sudden discharge of static electricity from a finger or other conductor can destroy static-sensitive devices or microcircuitry. Often the spark is neither felt nor heard, but damage occurs.

An electronic device exposed to electrostatic discharge might not be affected at all and can work perfectly throughout a normal cycle. Or the device might function normally for a while, then degrade in the internal layers, reducing its life expectancy.

Use the following grounding precautions when packaging and transporting equipment:

• To avoid hand contact, transport products in static-safe containers, such as tubes, bags, or boxes.

• Protect all electrostatic-sensitive parts and assemblies with conductive or approved containers or packaging.

• Keep electrostatic-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.

• Always be properly grounded when touching a sensitive component or assembly.

• Store reusable electrostatic-sensitive parts from assemblies in protective packaging or nonconductive foam.

• Use transporters and conveyors made of antistatic belts and roller bushings. Ensure that mechanized equipment used for moving materials is wired to ground and that proper materials are selected to avoid static charging. When grounding is not possible, use an ionizer to dissipate electric charges.

Use the following grounding precautions at workstations:

• Cover the workstation with approved static-shielding material.

• Use a wrist strap connected to a properly grounded work surface and use properly grounded tools and equipment.

• Use conductive field service tools, such as cutters, screwdrivers, and vacuums.

• When fixtures must directly contact dissipative surfaces, use fixtures made only of static-safe materials.

• Keep the work area free of nonconductive materials, such as ordinary plastic assembly aids and Styrofoam.

• Handle electrostatic-sensitive components, parts, and assemblies by the case or PCM laminate. Handle these items only at static-free workstations.

• Avoid contact with pins, leads, or circuitry.

• Turn off power and input signals before inserting or removing connectors or test equipment.

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.

• When standing, use foot straps and a grounded floor mat. Foot straps (heel, toe, or boot straps) can be used at standing workstations and are compatible with most types of shoes or boots. On conductive floors or dissipative floor mats, use foot straps on both feet with a minimum of one megohm resistance between the operator and ground. To be effective, the conductive strips must be worn in contact with the skin.

Other grounding equipment recommended for use in preventing electrostatic damage includes:

• Antistatic tape.

• Antistatic smocks, aprons, and sleeve protectors.

• Conductive bins and other assembly or soldering aids.

• Nonconductive foam.

• Conductive tabletop workstations with ground cords of one megohm resistance.

• Static-dissipative tables or floor mats with hard ties to the ground.

• Field service kits.

• Static awareness labels.

• Material-handling packages.

• Nonconductive plastic bags, tubes, or boxes.

• Metal tote boxes.

• Electrostatic voltage levels and protective materials.

A product can be degraded by as little as 700 V.

When you back up modifications since your last backup, you are creating system recovery points. This allows you to save 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 your system.

The first system recovery point, a snapshot of the entire image, is automatically created the first time you perform a backup. Subsequent recovery points make a copy of changes made after that time.

HP recommends that you create recovery points:

• Before you add or extensively modify software or hardware.

• Periodically, whenever the system is performing optimally.

Recovering to an earlier recovery point does not affect data files or e-mails created since that recovery point.

After you create a recovery point, you are prompted to schedule subsequent recovery points. You can schedule recovery points for a specific time or event in your system.

To create and schedule a system recovery point:

1. Select Start > All Programs > HP Backup & Recovery > HP Backup and Recovery Manager.
