Power Management functions of the computer are designed to conserve
power. All Power Management functions can be configured from the
Setup Configuration Utility (SCU), described later in this chapter.
Automatic Power Management
Automatic Power Management operates at two levels as described in the
following paragraphs.
Local Power Management
Local Power Management controls computer subsystems. When a
subsystem is inactive for a period of time, it is automatically shut down
or slowed to reduce power consumption. The subsystem returns to an
active state when it is accessed.
Subsystems under Power Management include:
■ Hard disk drive
■ Diskette drive
■ CD-ROM drive
■ LCD display panel
Global Power Management
Global Power Management automatically puts the computer into Suspend
mode when the computer is inactive for a period of time. The computer
wakes up whenever activity resumes.
The time-out settings for Suspend mode are set up in the SCU program.
The computer uses Suspend-to-RAM (Standby) or Suspend-to-Disk
(Hibernation) depending on the Suspend Data To setting in the SCU
program.
Manual Power Management
Suspend mode can be initiated at any time in one of two ways:
■ By pressing Fn + F12.
■ By closing the top cover, if the Cover Close option is set to Suspend
in the SCU program.
Product Description1-5
Suspend-to-Disk (Hibernation)
When the computer suspends to disk, the system preserves all the running
application programs as a file in a Suspend-to-Disk partition on the hard
disk. The computer then turns off automatically. When the computer is
powered on, the system reads the file from the Suspend-to-Disk partition
back into memory, returning the computer to the state it was in before it
was suspended.
If there is no Suspend-to-Disk partition on the hard disk, use the
HIBERNAT utility to create the partition, in order to be able to use the
Suspend-to-Disk feature.
Suspend-to-RAM (Standby)
When the computer suspends to RAM, several subsystems enter standby
or power-off mode to conserve power. The system wakes up when any
key is pressed. Resume Timer and Ring Resume options also wake the
system from Suspend-to-RAM.
1.4 Setup Configuration Utility (SCU)
The system comes with a Setup Configuration Utility (SCU). This utility
configures BIOS settings via menu-driven utilities. Settings are stored in
the CMOS RAM.
The SCU must be used when:
■ An error message indicates that the SCU should be run.
■ Factory default settings need to be restored (after BIOS upgrades).
■ Specific settings must be modified.
Starting the SCU
The SCU resides on the system ROM chip. Start the utility by pressing
F10 during initial power up.
1-6Product Description
Main SCU Screen
The SCU main screen is divided into three areas:
Menu area – lists the available menu titles, across the top of the screen.
Each menu title provides a pull-down menu of item settings.
Display area – displays current system settings. This section also
displays submenus for items that provide multiple options.
Information and navigation area – provides keyboard/mouse
instructions for moving around and making decisions.

1.5 Compaq Configuration Record Utility
Compaq Configuration Record Utility is an online information-gathering
tool meant to replace the DOS based Inspect utility. It runs from within
Windows and gathers critical hardware and software information from
various sources to give a complete view of the computer. The Compaq
Configuration Record Utility delivers comprehensive configuration
capture, provides a means for automatically identifying and comparing
configuration changes, and has the ability to maintain a computer
configuration history. The information can be saved as a history of
multiple sessions.
The Compaq Configuration Record Utility captures data as sessions; a
session is defined as an organized group of data describing the configured
state of the system at a specific point in time.
The session information is maintained in a log file, located in the same
directory as the executable portion of the program. This file contains all
of the ASCII text configuration information captured for a session. This
file can be analyzed locally by the Configuration Record Utility, or it can
be sent to another location such as a help center, or to Compaq.
The sessions are organized as two distinct types:
Active
The Active session (referenced as session now.log) is the most recent
information captured. The utility overwrites this session each time a
sample is taken.
Original
The Original session (referenced as session base.log) is the first session
sampled. The Compaq Configuration Record Utility will treat this
session as a "master configuration" and the utility will never overwrite
this session.
1-16Product Description
1.6 Gathering Information
The comparison feature provides several reports that enable the
administrator to specify the particular type and level of information that
will be most useful in a particular case. The different report types
available are:
Show Only Differences Report
This feature provides a mechanism for filtering the level of information
displayed when comparing two different configuration snapshots (or
sessions). For example, when a user requests that Configuration Record
Utility generate a comparison of sessions using the “differences” filter,
the tool automatically compares those two sessions (which are already
stored in a Configuration Record file). It then generates a report that
shows only the differences between the two generations. In this case, the
differences report will include all information recorded, such as changes
in amounts of free memory. Reviewing the differences occurring between
different configuration snapshots can help identify trends causing
intermittent computer problems, such as low memory resources.
Product Description1-17
Show Details and Differences Report
This report provides the level of detail that is necessary for service
personnel to get a clear picture of the system configuration. It provides a
much greater depth of information on hardware, operating system
services, and drivers that are running on the computer.
The Compaq Configuration Record Utility is supported under
Windows 95, Windows 98, and Windows NT 4.0. This utility is available
on SoftPaq.

TROUBLESHOOTING
2.1 Service Considerations
When troubleshooting the Compaq Notebook 100, it is important to
obtain all facts about the situation. Obtain details of the problem and any
circumstances surrounding the problem. Obtain all error codes or beep
codes. Once all facts have been gathered, determine possible causes and
search for issues.
2.2 Basic Troubleshooting Checklist
Use the following checklist in the event minor problems are encountered:
■ Is the computer connected to an external power source or does it
have a fully charged battery pack installed?
■ Is the computer turned on and is the power indicator illuminated?
■ Are all cables connected properly and secure?
■ Did the diskette drive contain a non-bootable diskette when the
system was powered up?
■ Does the computer have all necessary device drivers?
■ Have printer drivers been installed for each application?
■ Was the Windows operating system properly exited?
■ Has the computer hard drive been scanned for viruses?
Troubleshooting2-1
2.2 Power-On Self Test (Post)
When the computer starts, the system BIOS runs a series of internal
checks on the hardware. This allows the computer to detect problems as
early as the power-on stage. The POST alerts you to problems by
displaying error messages.
If POST detects an error, the system displays an error message on the
display. If the error occurs before the display comes up, error codes or
system beeps indicate the POST error.
The value for diagnostic POST (378H) is written at the beginning of the
test. Therefore, if the test fails, you can determine where the problem
occurred by reading the last value written to POST 378H by the PIO
Debug Board Plug at the PIO port. The following table lists error codes
in sequential order on the PIO Debug Board.

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 Phillips screwdriver
■ 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.
IMPORTANT: As you remove each subassembly from the computer, place
it (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.
Removal and Replacement Preliminaries4-1
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.
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:
■ 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.
■ Before removing a diskette drive or CD-ROM drive, ensure that a
diskette or disc is not in the drive. Ensure that the CD-ROM 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 that have at least one inch of shock-proof
foam.
■ Avoid dropping drives from any height onto any surface.
4-2Removal and Replacement Preliminaries
■ After removing a hard drive, place it into a static-proof bag.
■ After removing a CD-ROM drive or a diskette drive, place it into a
static-proof bag.
■ Do not use excessive force when inserting a drive into a drive bay.
■ Avoid exposing a hard drive to products that have magnetic fields
such as monitors or speakers.
■ Avoid exposing a drive to temperature extremes or to liquids.
■ 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.”
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.
Removal and Replacement Preliminaries4-3
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 they arrive
at static-free workstations.
■ Place items on a grounded surface before removing them from their
container.
■ Always be properly grounded when touching a sensitive component
or assembly.
■ Place reusable electrostatic-sensitive parts from assemblies in
protective packaging or non-conductive foam.
■ 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:
■ Cover the workstation with approved static-dissipative material
(refer to Table 4-2 later in this chapter).
■ Use a wrist strap connected to a properly grounded work surface and
use properly grounded tools and equipment.
■ Use field service tools, such as cutters, screwdrivers, and vacuums
that are conductive.
■ When using fixtures that must directly contact dissipative surfaces,
use fixtures made of static-safe materials only.
■ Keep 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 them only at static-free
workstations.
4-4Removal and Replacement Preliminaries
■ 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 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.
■ 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-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 include:
■ Antistatic tape
■ Antistatic smocks, aprons, or sleeve protectors
■ Conductive bins and other assembly or soldering aids
■ Non-conductive foam
■ Conductive tabletop workstations with ground cord of one-megohm
resistance
■ Static-dissipative table or floor mats with hard tie to ground
■ Field service kits
■ Static awareness labels
■ Material-handling packages
■ Non-conductive plastic bags, tubes, or boxes
■ Metal tote boxes
■ Electrostatic Voltage Levels and Protective Materials
