3.2 System Recovery

The computer system recovery process provides several ways to recover optimal system functionality. For best results, attempt to recover optimal computer functionality by using the following procedures in the order described here.

3–6 Maintenance and Service Guide

Safeguarding Your Data

Software or devices added to the computer can cause your system to become unstable. To safeguard your documents, store personal files in the My Documents folder and periodically create a backup copy of the My Documents folder.

Using Altiris Local Recovery

Altiris Local Recovery is a preloaded application that protects the files on your computer by storing copies of files, called snapshots. If files on your computer are accidentally deleted or corrupted, you can easily restore the files yourself. You can also restore your complete file system to a previous state.

Altiris Local Recovery provides protection of files by backing up files to a hidden Altiris recovery partition. When you install the software, the Recovery Agent Partition Wizard guides you through the process of creating the recovery partition. After the partition is created, the computer restarts and creates the first snapshot. After the snapshot is created, the computer restarts, making the snapshot available for recovery through Windows.

By default, Local Recovery automatically takes snapshots of your files on a regular basis. You can change the snapshot schedule. For more information, refer to the Altiris Local Recovery Help.

To access your snapshots in the Altiris Recovery Agent folder:

Software Update and Recovery

1. Right-click the Altiris Recovery Agent icon on your desktop.

2. Click Open.

To restore one of the listed snapshots, drag the snapshot file to the appropriate location on your hard drive.

For more information on configuring and using Altiris Local Recovery, visit the HP Web site at or open the software and click Help on the menu bar.

Maintenance and Service Guide 3–7

http://www.hp.com/go/easydeploy,

Software Update and Recovery

Using System Restore Points

System Restore is a Windows operating system feature that allows you to reverse undesirable changes to your computer by restoring the computer to an earlier state, called a restore point. A restore point is a “snapshot” of your software, drivers, and operating system files at a particular time. The computer automatically creates restore points at regular intervals and may create additional restore points when you change your personal settings or add software or hardware.

You can manually create additional restore points to provide increased protection for your system files and settings. It is recommended that you manually create restore points

■ Before you add or extensively modify software or hardware.

■ Periodically, whenever the system is performing optimally.

Restoring to any restore point does not affect your data files. For example, restoring your system software to an earlier state will not affect documents or e-mails that you saved after that time.

If you do not like the results of your restoration, you can

✎

reverse the restoration.

Creating a System Restore Point

To create a system restore point:

1. Select Start > Help and Support.

2. Click System Restore.

The System Restore window opens.

3. Click Create a restore point, and then click Next.

4. Follow the on-screen instructions.

3–8 Maintenance and Service Guide

Restoring to a Restore Point

1. Select Start > Help and Support.

2. Click System Restore.

The System Restore window opens.

3. Click Restore my computer to an earlier time, and then click Next.

4. Follow the on-screen instructions.

Reinstalling Applications

Applications preinstalled or preloaded on your computer can be reinstalled by using the Recovery disc or a third-party software disc.

In most cases, the applications preloaded on your computer,

✎

such as those available in the Software Setup utility, can be reinstalled from your hard drive. To access the Software Setup utility, select Start > All Programs > Software Setup.

Software Update and Recovery

The application reinstallation process replaces corrupted system files within the application and reinstalls deleted system files within the application.

■ In most cases: If the application you are reinstalling is still

installed on your computer, the reinstallation process does not affect your settings within the application.

■ In all cases: If an application has been deleted from your

computer, the reinstallation process reinstalls the application or utility to the factory image but cannot restore your personal settings.

5.2 Service Considerations

The following sections include some of the considerations that you should keep in mind during disassembly and assembly procedures.

As you remove each subassembly from the computer, place

✎

the subassembly (and all accompanying screws) away from the work area to prevent damage.

Plastic Parts

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 and Connectors

CAUTION: When servicing the computer, ensure 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. 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.

5.3 Preventing Damage to Removable Drives

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.”

5.4 Preventing Electrostatic Damage

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 may not be affected at all and can work perfectly throughout a normal cycle. Or the device may function normally for a while, then degrade in the internal layers, reducing its life expectancy.

5.5 Packaging and Transporting Precautions

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.

5.6 Workstation Precautions

Use the following grounding precautions at workstations:

■ Cover the workstation with approved static-shielding material

(refer to

■ 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.
