Chapter 2 - Troubleshooting
Introduction
This chapter contains troubleshooting information for the computer. The
basic steps in troubleshooting include:
1. Completing the preliminary steps listed in Section 2.1.
2. Running the Power-On Self-Test (POST) as described in Section 2.4.
3. Running the Computer Checkup (TEST) as described in Section 2.5.
4. Performing the recommended actions described in the diagnostic tables
in Section 2.7 if you are unable to exercise POST or Computer Checkup
or if the problem persists after running POST and Computer Checkup.
Adhere to the following guidelines when troubleshooting:
o Complete the recommended actions in the order in which they are given.
o Repeat POST and Computer Checkup after each recommended action until the
problem is resolved and the error message does not return.
o Once the problem is resolved, do not complete the remaining recommended
actions.
o Refer to Chapter 5 for any removal and replacement procedures that are
recommended.
Preliminary Steps
IMPORTANT: Use the AC adapter when running POST, Computer Setup, or
Computer Checkup. A low battery condition could initiate
Standby and interrupt the test.
Before running POST and Computer Checkup, complete the following steps:
1. If a power-on password has been established, type the password and
press Enter.
NOTE: The key icon appears on the status display when the computer is
turned on to indicate that QuickLock/QuickBlank has been initiated.
Type the power-on password to exit QuickLock/QuickBlank. If the
password is unknown, it must be cleared (see Section 2.2).
2. Run Computer Setup (Section 2.3).
3. Use the Hotkeys to adjust the brightness (Fn+F9) and contrast (Fn+F10)
to the center of their ranges and leave the display open. On models
with color TFT displays, contrast is not adjustable.
4. Turn off the computer and all external devices.
5. Disconnect any external devices that you do not want to test. If you
want to use the printer to log error messages, leave it connected to
the computer.
NOTE: If a problem only occurs when an external device is connected to the
computer, the problem could be with the external device or its
cable. Isolate the problem by running POST with and without the
external device connected.
6. Use Advanced Diagnostics and loopback plugs in the serial and parallel
connectors if you plan to test these ports. To run Advanced
Diagnostics, complete the following steps:
a. Insert the Diagnostics diskette into the diskette drive and turn on
the computer.
b. At the Welcome Screen, enter Ctrl+A.
c. Press Enter to accept OK.

7. Ensure that the battery pack is installed in the computer and the AC
adapter is connected to the computer and plugged into an AC power
source.
After completing the preliminary steps, run POST (Section 2.4) and
Computer Checkup (Section 2.5).
Running Computer Setup
The ROM-based Computer Setup displays the current system configuration and
allows you to set system and power management parameters. These parameters
are stored in CMOS, and a backup copy is saved in a parameter block in
system flash ROM.
You can access Computer Setup by pressing F10 when the prompt appears
after you turn on the computer. The following configuration parameters can
be changed in Computer Setup:
o Power conservation (when)
o Power conservation (level)
o Hibernation on/off

o PC Card slots disable
o Resume password on/off
o Boot memory test
o Keyboard numlock
o Boot sequence
o Boot display
o Serial port settings
o Parallel port settings
o Power-on password
o Diskette drive boot disable
To run Computer Setup, complete the following steps:
Computer Setup automatically recognizes and configures the system for new
Compaq devices. It does this without prompting you for information about
the devices. However, if you add a memory expansion board, a prompt
appears the next time you turn on the computer, notifying you of the new
memory configuration.
The first Computer Setup screen displays current settings for the system,
ports, and devices. The status bar at the bottom of the screen gives
instructions for navigating and choosing options. The status bar also
displays descriptions as you highlight menus and menu options.
NOTE: If the main system board is replaced, the serial number on this
screen changes to 0 (zero).
Select one of the menus from the menu bar at the top of the screen to view
or to change the following configuration settings:
o Initialization startup preferences
o Ports, including serial and parallel
o Power, including Power Management and Hibernation
o Security, including setup and power-on passwords and device disabling
Initialization Menu
Select the Initialization menu to change the initialization (startup)
settings for running the POST memory tests, numlock on or off, the
drive boot sequence, and the active display.
Ports Menu
Select the Ports menu to change the default input/output (I/O) addresses
and interrupt requests (IRQs) for serial and parallel ports.
NOTE: If you select conflicting settings for the ports, the system
automatically changes one of the settings.
Power Menu
Select the Power menu to enable or disable Power Management, low-battery
warning beeps, and an external energy-saving monitor. The factory default
settings are:
o Power Management Enabled While on Battery
o Conservation Level Medium

o External Energy Saving Monitor Disabled
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> CAUTION <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
If you disable Power Management or Hibernation, you must take immediate
action to resolve a low-battery condition to prevent losing unsaved
information.
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>><<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
If you elect to disable the low-battery warning beeps, a low-battery
condition is indicated only by a blinking battery light. If you disable
Power Management or Hibernation, information in memory is not
automatically saved during a critical low-battery condition.
If you enable the selection for an external energy-saving monitor, it
enters low-power mode when the screen timeout occurs. If you enable this
selection and do not have an energy-saving monitor, the screen display may
become distorted.
Under Power Management, you can select whether to enable Power Management
while on AC or battery power, only while on battery power, or never
(disabled).
If you enable Power Management, you can select from four conservation
levels: high, medium, none (drain), or custom. The conservation level sets
the timeouts for Standby, Hibernation, drives, and screens. A timeout is a
period of inactivity after which power is turned off to the system or
component.
o High: Provides the maximum amount of power conservation and the maximum
battery operating time from a single charge.
o Medium (default): Provides a balance between performance and battery
life.
o Custom: Conserves power according to specified timeout settings.
o None (Drain): Provides no power conservation features; the system runs
at full speed.
Security Menu
Select the Security menu to set, change, or delete the setup and power-on
passwords and to enable/disable QuickLock/QuickBlank, power-on password
from Standby, diskette drives, ports, and PC Card slots.

effect until the computer is restarted.
o Exit (No Save): Exits and does not save the changes you have made.
o Restore Factory Defaults: Replaces the current configuration settings
with the original factory default settings.
POST Error Messages
This chapter contains typical error messages that you may encounter during
the power-on self-test (POST). POST is a series of tests that run every
time you turn on the computer. POST verifies that the system is configured
and functioning properly. A successful POST is followed by one or two
short beeps.
If you receive an error message listed on the following pages, follow the
recommended action. If you receive an error message that is not listed,
run Computer Checkup from the Diagnostics diskette. Information about
running Computer Checkup is presented later in this chapter.
If POST detects an error, one of the following events occurs:
o A message with the prefix "WARNING" appears informing you where the
error occurred. The system pauses until you press F1 to continue.
o A message with the prefix "FATAL" appears informing you where the error
occurred. After the message, the system emits a series of audible beeps.
The system then stops.
o The system emits a series of audible beeps. The system then stops.
Warning messages indicate a potential problem exists such as a system
configuration error. When F1 is pressed, the system should resume. You
should be able to correct problems that produce WARNING messages.
IMPORTANT: When a WARNING message includes the prompt to "RUN SCU," run
Computer Setup. (Computer Setup replaces the SCU utility.)
Fatal errors emit a beep and may display a FATAL message. Fatal errors
indicate severe problems, such as a hardware failure. Fatal errors do not
allow the system to resume. Some of the Fatal error beep codes are listed
at the end of this section.

Chapter 3 - Illustrated Parts
Introduction
This chapter provides an illustrated parts breakdown and a reference for
spare part numbers for the Compaq Armada 1100 Family of Personal
Computers.
The computer combines a display assembly and system unit module. The
display and system unit module are joined together by clutches on either
side, which are secured by screws in the chassis and display enclosure,
and which allow the display to open and close. The system unit module is
secured to the CPU base by screw locks in the rear and screws in the
bottom of the system unit enclosure. The display assembly is secured by
screws installed in the front bezel of the display enclosure.
System Unit Module Overview
The system unit module (Figure 3-2) contains the following major
components:
o Hard drive - The hard drive mounts to the system chassis with a hard
drive bracket and connects directly to the system board with no
intervening cables. The hard drive bracket attaches to the hard drive
with four screws. The drive is protected by an insulator between the
system board and the drive.
o Memory expansion board - System memory can be upgraded with an optional
memory expansion board. An expansion board is added or replaced from the
bottom of the computer through the memory compartment cover. The memory
expansion board connects directly to the system board with one
connector.
o Battery pack - The nickel metal hydride battery pack is accessed through
the battery compartment.
o Integrated trackball assembly - The optical trackball is centrally
located at the bottom of the keyboard assembly. The assembly consists of
the trackball, retaining ring, and connector. The trackball assembly
connects directly to the system board and is secured by two screws.
o System board with processor - The system board is mounted directly to
the system chassis. All removable components connected to the system
board, except for the PC Card rails, EMI clip, and heatspreader must be
removed prior to removing the system board. The processor is soldered to
the system board and is not removable. It is covered by a heatspreader
designed to dissipate heat generated by the processor. There is a
bottom heatsink on the chassis, beneath the system board and the
processor. A spare parts kit containing a replacement system board comes
with the processor and heatspreader built on it. A chassis spare parts
kit includes the bottom heatsink.
o PC Card rails - The PC Card rails are replaceable and are secured by two
screws from the bottom of the system board and a clip on top of the
rails. The header attaches directly to the system board and cannot be
removed. The top and bottom PC Card ejection levers are replaceable.
o Real-Time Clock Battery - The battery is located in the left corner at
the rear of the computer.
o Diskette drive - The diskette drive attaches to the system board by a
bracket and three screws; the bracket also attaches to the heatspreader
with two screws. The drive is connected by a diskette drive cable and
LIF connector. The bracket attaches to the drive with four screws. The
drive is protected by an insulator between the system board and the
drive.
The memory expansion board and battery pack are accessed from the bottom
of the computer. To service the remaining system unit module components,
the keyboard assembly must be removed. A complete list of replaceable
parts is included in Table 3-1.
Display Assembly Overview
All display assemblies (Figure 3-3) include the following replaceable
parts:
o Bezel
o Enclosure latches
o Liquid crystal display (LCD) panel
o Shield
o Enclosure
o Display cable
o Display ground cable
o Inverter board
o Clutches
The display cable is a prefolded, flex cable that connects to the display
inverter board with a low insertion force (LIF) connector. The other end
of the display cable is exposed at the bottom of the display enclosure and
connects to the system board with a zero insertion force (ZIF) slide
connector. The cable connects to the display panel directly on the CTFT
model and through a crossover PCA on the CSTN models.
The display ground cable connects to the display shield on one end, and
the other end clips to the flex ground bracket located above the serial
port between the system board and system chassis.
The display inverter board is aligned to the right of the display
enclosure with pins. One end connects to the display cable; the other end
connects to the backlight cable of the LCD panel.
To replace the display assembly, the assembly must be removed from the
system unit module. This is done by removing the keyboard assembly,
disconnecting the display cable and display ground cable from the system
unit module, removing the tilt feet and handle brackets, removing the rear
clutch screws, and lifting off the display assembly.
To service display components, do not remove the display assembly from the
system unit module (unless replacement of the display enclosure or clutch
is required). Access display components (inverter board or latches) by
removing the bezel secured with four screws on the front of the display.

Chapter 4 - Removal and Replacement Preliminaries
Introduction
This chapter provides general service information for the Compaq Armada
1100 Family of Personal Computers.
Adherence to the procedures and precautions described in this chapter is
essential for proper service.
Electrostatic Discharge
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 or heard, but damage occurs. An electronic device exposed to
electrostatic discharge (ESD) may not be affected at all and will work
perfectly throughout a normal cycle. Or it may function normally for a
while, then degrade in the internal layers, reducing its life expectancy.
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.
Generating Static
Table 4-1 shows how different activities generate static electricity and
at different electrostatic voltage levels.

Preventing Electrostatic Damage to Equipment
Many electronic components are sensitive to ESD. Circuitry design and
structure determine the degree of sensitivity. The following proper
packaging and grounding precautions are necessary to prevent damage:
o Protect all electrostatic parts and assemblies with conductive or
approved containers or packaging.
o Keep electrostatic-sensitive parts in their containers until they arrive
at static-free stations.
o Place items on a grounded surface before removing them from their
container.
o Always be properly grounded when touching a sensitive component or
assembly.
o Place reusable electronic-sensitive parts from assemblies in protective
packaging or conductive foam.
Use transporters and conveyors made of antistatic belts and metal roller
bushings. Mechanized equipment used for moving materials must be wired to
ground and proper materials selected to avoid static charging. When
grounding is not possible, use an ionizer to dissipate electric charges.
Removing Batteries
Compaq recommends that you remove all batteries from the computer before
beginning the disassembly procedures. Failure to do so could cause damage
to computer components.
Preventing Damage to Drives
To prevent static damage to hard drives, use the following precautions:
o Handle drives gently, using static-guarding techniques.
o Store drives in the original shipping containers.
o Avoid dropping drives from any height onto any surface.
o Handle drives on surfaces that have at least one inch of shock proof
foam.
o Always place drives with the PCB assembly side down on the foam.
Grounding Methods
The method for grounding must include a wrist strap or a foot strap at a
grounded workstation. When seated, wear a wrist strap connected to a
grounded system. When standing, use footstraps and a grounded floor mat.

Method Voltages
===========================================================================
Antistatic Plastic 1,500
Carbon-Loaded Plastic 7,500
Metallized Laminate 15,000
===========================================================================
Grounding Workstations
To prevent static damage at the workstation, use the following
precautions:
o Cover the workstation with approved static-dissipative material. Provide
a wrist strap connected to the work surface and properly grounded tools
and equipment.
o Use static-dissipative mats, heel straps, or air ionizers to give added
protection.
o Handle electrostatic sensitive components, parts, and assemblies by the
case or PCB laminate. Handle them only at static-free workstations.
o Avoid contact with pins, leads, or circuitry.
o Turn off power and input signals before inserting and removing
connectors or test equipment.
o Use fixtures made of static-safe materials when fixtures must directly
contact dissipative surfaces.
o Keep work area free of non-conductive materials such as ordinary plastic
assembly aids and Styrofoam.
o Use field service tools, such as cutters, screwdrivers, vacuums, that
are conductive.
o Use a portable field service kit with a static dissipative vinyl pouch
that folds out of a work mat. Also use a wrist strap and a ground cord
for the work surface. Ground the cord to the chassis of the equipment
undergoing test or repair.
Grounding Equipment
Use the following equipment to prevent static electricity damage to the
equipment:
Wrist Straps are flexible straps with a minimum of 1 megohm +/- 10%
resistance to the ground cords. To provide proper ground, a strap must be
worn snug against the skin. On grounded mats without banana-plug
connectors, connect a wrist strap with alligator clips.
Heel straps/Toe straps/Bootstraps can be used at standing workstations and
are compatible with most types of boots and shoes. On conductive floors or
dissipative floor mats, use straps on both feet with a minimum of 1 megohm
resistance between operator and ground. To be effective, the conductive
strips must be worn in contact with the skin.
Recommended Materials and Equipment
Other materials and equipment that are recommended for use in preventing
static electricity include:
o Antistatic tape
o Antistatic smocks, aprons, or sleeve protectors
o Conductive bins and other assembly or soldering aids
o Conductive foam
o Conductive table-top workstations with ground cord of 1 megohm of
resistance
o Static dissipative table or floor mats with hard tie to ground
o Field service kits
o Static awareness labels
o Wrist straps and footwear straps providing 1 megohm +/- 10% resistance
o Material handling packages
o Conductive plastic bags
o Conductive plastic tubes
o Conductive tote boxes
o Metal tote boxes
o Opaque shielding bags
o Transparent metallized shielding bags
o Transparent shielding tubes
