Product Description  
Timeout Settings  
Timeout functions can be set up to power down computer  
components by selecting the Power Schemes tab from the power  
application in the operating system’s Control Panel. When a  
component such as the monitor, hard drive, system, or video is  
not in use, the component powers down to conserve power. The  
time out interval can be set from one minute up to several hours.  
The component will power up again when you access it or press  
any key.  
Setting Standby  
Standby is initiated by pressing the Fn+F4 hotkeys or  
automatically by the computer if it reaches the defined percentage  
of battery pack power remaining. When Standby is initiated,  
several subsystems will power off to conserve energy. The system  
will wake up from Standby when a key is pressed. Although the  
Standby mode maintains the information and opens the file upon  
wake-up, any unsaved information is lost if the computer is  
turned off before ending Standby.  
Hibernation  
Hibernation is an energy-saving feature and safeguard that saves  
information in RAM to a hibernation file on the hard drive, then  
shuts down the computer. Hibernation is initiated by the computer  
when the computer reaches the defined percentage of battery  
pack power remaining. To wake the computer from Hibernation,  
press the power button. When you resume work, the information  
returns to the screen where you left off.  
The computer uses the operating system with a power  
management utility that helps you maintain and conserve power  
when the computer is running on battery power.

Product Description  
Standby  
Standby is an energy-saving feature that conserves power and  
reduces startup time.  
Standby reduces power to system components that are not being  
used. Standby can be initiated by you or by the system. When  
Standby is initiated, all work is saved in random access memory  
(RAM) and the screen is cleared. When work is resumed, the  
information returns to the screen.  
Refer to Section 1.4 in this chapter to identify the Power, Standby,  
and Hibernation controls.

Product Description  
1.4 Design Overview  
This section presents a design overview of key parts and features  
of the computer. Refer to Chapter 3, “Illustrated Parts Catalog”  
and Chapter 5, “Removal and Replacement Procedures.”  
The system board provides the following device connections:  
I Memory expansion board  
I Hard drive  
I Display  
I Keyboard/TouchPad  
I Audio  
I Intel Pentium III or Intel Celeron Processors  
I Fan  
I PC Card  
I Modem or modem/NIC  
I Microphone  
The computer uses an electrical fan for ventilation. The fan is  
controlled by a temperature sensor and is designed to turn 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 right side of the computer.  
CAUTION: To properly ventilate the computer, allow at least a 3-inch  
(7.6 cm) clearance on the left and right sides of the computer.

subassemblies, no one should attempt to make repairs at the  
component level or to make 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.  
Utilities that are preinstalled on the computer include:  
I PhoenixBIOS Setup Utility—Allows you to modify or  
restore factory default settings and configure the system  
BIOS to diagnose and solve minor problems.  
I Power Management—Allows you to reduce your computer  
power consumption. Power Management information is  
contained in Chapter 1.  
I Security—Allows you to set or remove your power-on  
password. Security information is contained in Chapter 1.

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:  
I Magnetic screwdriver  
I Phillips P0 screwdriver  
I Tool kit (includes connector removal tool, loopback plugs,  
and case utility tool)  
4.2 Service Considerations  
Listed below are some of the considerations that you should keep  
in mind during disassembly and assembly procedures.  
As you remove each subassembly from the computer, place it  
I(and all accompanying screws) away from the work area to  
prevent damage.  
Maintenance and Service Guide  
4–1  
             
Removal and Replacement Preliminaries  
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  
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; they tear easily.  
CAUTION: When servicing the computer, ensure that cables are  
placed in their proper location during the reassembly process.  
Improper cable placement can damage the computer.  
Ä
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 these  
precautions:  
I 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, then shut it down.  
I Before removing a diskette drive or optical drive, ensure that  
a diskette or disc is not in the drive. Ensure that the optical  
drive tray is closed.  
4–2  
Maintenance and Service Guide  
           
Removal and Replacement Preliminaries  
I Before handling a drive, ensure that you are discharged of  
static electricity. While handling a drive, avoid touching the  
connector.  
I Handle drives on surfaces that have at least one inch of  
shock-proof foam.  
I Avoid dropping drives from any height onto any surface.  
I After removing a hard drive, CD-ROM drive, or a diskette  
drive, place it into a static-proof bag.  
I Avoid exposing a hard drive to products that have magnetic  
fields such as monitors or speakers.  
I Avoid exposing a drive to temperature extremes or to liquids.  
I If a drive must be mailed, do the following: place the drive  
into a bubble pack mailer or other suitable form of protective  
packaging; label the package “Fragile: Handle With Care.”  
Maintenance and Service Guide  
4–3  
Removal and Replacement Preliminaries  
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 may not be  
affected at all and can work perfectly throughout a normal cycle.  
It 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:  
I To avoid hand contact, transport products in static-safe  
containers such as tubes, bags, or boxes.  
I Protect all electrostatic-sensitive parts and assemblies with  
conductive or approved containers or packaging.  
I Keep electrostatic-sensitive parts in their containers until they  
arrive at static-free workstations.  
I Place items on a grounded surface before removing them  
from their container.  
I Always be properly grounded when touching a sensitive  
component or assembly.  
4–4  
Maintenance and Service Guide  
       
Removal and Replacement Preliminaries  
I Place reusable electrostatic-sensitive parts from assemblies in  
protective packaging or non-conductive foam.  
I Use transporters and conveyers made of antistatic belts and  
roller bushings. Ensure that mechanized equipment used for  
moving materials is wired to ground, and that proper  
materials were 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:  
I Cover the workstation with approved static-dissipative  
material (refer to Table 4-2).  
I Use a wrist strap connected to a properly grounded work  
surface and use properly grounded tools and equipment.  
I Use conductive field service tools, such as cutters,  
screwdrivers, and vacuums.  
I When using fixtures that must directly contact dissipative  
surfaces, use fixtures made of static-safe materials only.  
I Keep the work area free of nonconductive materials such as  
ordinary plastic assembly aids and Styrofoam.  
I Handle electrostatic-sensitive components, parts, and  
assemblies by the case or PCM laminate. Handle them only at  
static-free workstations.  
I Avoid contact with pins, leads, or circuitry.  
I Turn off power and input signals before inserting or removing  
connectors or test equipment.  
Maintenance and Service Guide

Removal and Replacement Preliminaries  
4.7 Grounding Equipment and Methods  
Grounding equipment must include either a wrist strap or a foot  
strap at a grounded workstation.  
I When seated, wear a wrist strap connected to a grounded  
system. Wrist straps are flexible straps with a minimum of  
one megaohm ±10% resistance in the ground cords. To  
provide proper ground, wear a strap snug against the skin at  
all times. On grounded mats with banana-plug connectors,  
connect a wrist strap with alligator clips.  
I 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  
them on both feet with a minimum of one-megaohm  
resistance between the operator and ground. To be effective,  
the conductive strips must be worn in contact with the skin.  
I Other grounding equipment recommended for use in  
preventing electrostatic damage includes:  
I Antistatic tape  
I Antistatic smocks, aprons, or sleeve protectors  
I Conductive bins and other assembly or soldering aids  
I Non-conductive foam  
I Conductive tabletop workstations with ground cord of  
one-megaohm resistance  
I Static-dissipative table or floor mats with hard tie to ground  
I Field service kits  
I Static awareness labels  
I Material-handling packages

Follow these steps to replace a damaged thermal pad:  
a. Carefully peel the old thermal pad from the heat  
sink area.  
b. Use a plastic straight edge tool (such as a credit card) to  
remove any thermal pad residue. Glue residue does not  
need to be totally removed. The glue used on the thermal  
pad has thermal conducting properties and will flow  
together with the glue from the new thermal pad.  
CAUTION: Do not use any metal tools when removing thermal pad  
residue from the heat sink or processor. Failure to follow this  
caution can result in damage to these components and system  
failure.
