Product Description  
1.5 Design Overview  
This section presents a design overview of key parts and features  
of the computer. Refer to Chapter 3, “Illustrated Parts Catalog,”  
to identify replacement parts, and Chapter 5, “Removal and  
Replacement Procedures,” for disassembly steps.  
The system board provides the following device connections:  
Memory module  
Mini PCI communications devices  
Hard drive  
Display  
Keyboard and TouchPad  
Audio  
Intel Pentium M and Celeron M processors  
Fan  
PC Card  
CAUTION: To properly ventilate the computer, allow at least a 7.6-cm  
(3-inch) clearance on the left and right sides of the computer.  
Ä
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.

Troubleshooting  
WARNING: Only authorized technicians trained by HP should repair  
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.

load. If the operating system is working, the computer restarts the  
operating system after you exit Computer Setup.  
Pointing devices are not supported in Computer Setup; you  
must use the keyboard to navigate and make selections.

Removal and Replacement  
Preliminaries  
This chapter provides essential information for proper and  
safe removal and replacement service.  
4.1 Tools Required  
You will need the following tools to complete the removal and  
replacement procedures:  
Magnetic screwdriver  
Phillips P0 screwdriver  
Flat-bladed screwdriver  
Tool kit—includes connector removal tool, loopback plugs,  
and case utility tool

Removal and Replacement Preliminaries  
4.2 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 s) 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.

4.3 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.”

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  
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.

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  
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.

Removal and Replacement Preliminaries  
4.6 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 using 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.  
4.7 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.
