Product Description
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.
Maintenance and Service Guide 1–27
Troubleshooting
WARNING: Only authorized technicians trained by HP should repair
Å
this equipment. All troubleshooting and repair procedures are detailed
to allow only subassembly-/module-level repair. Because of the
complexity of the individual boards and subassemblies, do not attempt
to make repairs at the component level or modifications to any printed
wiring board. Improper repairs can create a safety hazard. Any
indication of component replacement or printed wiring board
modification may void any warranty or exchange allowances.
2.1 Computer Setup
Computer Setup is a preinstalled, ROM-based utility that can be
used even when the operating system is not working or will not

subassembly (and all accompanying screws) away from
the
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.
CAUTION: When servicing the notebook, ensure that cables are
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

4.3 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
hibernation, turn the notebook on, and then shut it down
in
through the operating system.
■ Before removing a diskette drive or optical drive, ensure that
diskette or disc is not in the drive and ensure that the optical
a
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.”

4.4 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
junctions.
silicon
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.

4.5 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
parts arrive at static-free workstations.
the
■ Place items on a grounded surface before removing items
their containers.
from
■ Always be properly grounded when touching a sensitive
component or assembly.
■ Store reusable electrostatic-sensitive parts from assemblies
protective packaging or nonconductive foam.
in
■ 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.

4.6 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, drivers, 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
■ Handle electrostatic-sensitive components, parts, and
assemblies by the case or PCM laminate. Handle these

■ When seated, wear a wrist strap connected to a grounded
system. Wrist straps are flexible straps with a minimum of
megohm ±10% resistance in the ground cords. To provide
one
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.
