ÄCAUTION: To properly ventilate the computer, allow at least a 7.6--cm
(3-inch) clearance on the left and right sides of the computer.
The computer uses an electric fan for ventilation. The fan is
controlled by a temperature sensor and is designed to be turned
on automatically when high temperature conditions exist. These
conditions are affected by high external temperatures, system
power consumption, power management/battery conservation
configurations, battery fast charging, and software applications.
Exhaust air is displaced through the ventilation grill located on
the left side of the computer.

the ROM version currently installed on the computer. For
more information, refer to “Accessing Computer
Information.”
CAUTION: If your computer is connected to a network, it is
recommended that you consult with your network administrator before
installing any software updates, especially system ROM updates.
Ä
The computer system ROM stores the BIOS software. The
BIOS initializes the operating system, determines how the
computer will interact with the hardware devices, and provides
and date.
✎
2. Access the updates through the HP Web site by visiting
(purchased separately). For information about obtaining the
Support Software CD, refer to “Obtaining the Support
Software CD.”

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
Software Update and Recovery
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:
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
or open the software and click Help on the menu bar.
Maintenance and Service Guide

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.

✎
utility, select Start > All Programs > Software Setup.
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.

Removal and Replacement Preliminaries
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
Ä
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.
5–2
Maintenance and Service Guide
Removal and Replacement Preliminaries
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.”
Maintenance and Service Guide

Removal and Replacement Preliminaries
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.

Maintenance and Service Guide
Removal and Replacement Preliminaries
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.
Maintenance and Service Guide
5–5
Removal and Replacement Preliminaries
5.6 Workstation Precautions
Use the following grounding precautions at workstations:
■
■
■
■
■
■
Cover the workstation with approved static-shielding material
(refer to Table 4-2, “Static-Shielding Materials”).
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.
5–6
Maintenance and Service Guide
Removal and Replacement Preliminaries
5.7 Grounding Equipment and
Methods
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
