1.5 Design Overview
This section presents a design overview of key parts and features
of the notebook. Refer to Chapter 4, “Illustrated Parts Catalog,”
to identify replacement parts, and Chapter 6, “Removal and
Replacement Procedures,” for disassembly steps.
The system board provides the following device connections:
■ AMD Turion 64 MT, Turion 64 ML, and Mobile AMD
Sempron processors
■ Audio
■ Display
■ Hard drive
■ Keyboard and TouchPad
■ Memory module
■ Mini PCI communications devices
■ PC Card
CAUTION: To properly ventilate the notebook, allow at least a 7.6-cm
Ä
(3-inch) clearance on the left and right sides of the notebook.
The notebook 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 notebook.
1–22 Maintenance and Service Guide
Troubleshooting
WARNING: Only authorized technicians trained by HP should repair
Å
this equipment. All troubleshooting and repair procedures are detailed

3.1 Software Updates
To stay current with the newest technology and maintain optimal
performance, install the latest versions of HP software on your
computer as they become available.
To update HP software:
1. Identify your computer model, product category, and series
or family. Prepare for a system ROM update by identifying
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
Ä
recommended that you consult with your network administrator before
installing any software updates, especially system ROM updates.
3
Recovery
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
for data transfer among hardware devices, including the time
and date.
2. Access the updates through the HP Web site
(
http://www.hp.com) or the Support Software CD (purchased
separately). For information about obtaining the Support
Software CD, refer to “Obtaining the Support Software CD.”
3. Install the updates.

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.
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

Software Update and Recovery
Using System Restore Points
System Restore is an 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.

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 notebook, 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 notebook, ensure that cables are
Ä
placed in their proper locations during the reassembly process.
Improper cable placement can damage the notebook.
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 notebook, damage to a
removable drive, or loss of information, observe the following
precautions:
■ Before removing or inserting a hard drive, shut down the
notebook. If you are unsure whether the notebook is off or
in hibernation, turn the notebook 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 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.

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.
Table 4-2, “Static-Shielding Materials”).

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
■ Material-handling packages
■ Nonconductive plastic bags, tubes, or boxes
■ Metal tote boxes
■ Electrostatic voltage levels and protective materials
