Intelligent Manageability consists of preinstalled software tools for the computer and
Compaq servers that assist in tracking, troubleshooting, protecting, and maintaining the
computer. It provides the following functions:
■
■
■
■
Asset Management: provides detailed configuration and diagnostic information.
Fault Management: prevents, predicts, and alerts of impending hardware
problems.
Security Management: protects unauthorized access to data and components.
Configuration Management: optimizes the computer by providing the latest
drivers, utilities, and software, which are available on CD-ROM and the Compaq
Web site at www.compaq.com/support/portables.
NOTE: For further help with Intelligent Manageability, select Start Å Compaq
Information Center Å Intelligent Manageability
Accessing the Web Agent
The computer may have a preinstalled Web Agent that allows computer configuration
information to be viewed using Web technology. To access this feature, select Start Å

If the computer does not have a preinstalled Web Agent, it can be downloaded from the
Compaq Web site at www.compaq.com.
Asset Management
Asset Management enables component information to be retrieved when on the road or
connected to the network.
Asset Management also enables the network administrator to remotely retrieve
information from any Compaq computer connected to the network. The information can
be used to assist in tracking and maintaining the computer and its components. It
provides the following information:
■
■
Inventory information—The network administrator can retrieve information about
the computer over the network by using Compaq Insight Manager or any PC
management tool provided by Compaq Solution Partners. Asset control information
retrieved from the computer includes:
■ Manufacturer, model, and serial number of Compaq computers, monitors, hard
drives, battery packs, memory boards, processor speeds, and operating systems
■ Asset tag
■ System board and ROM revision levels
■ BIOS settings
Diagnostic information—Diagnostics for Windows includes information on hard
drives, ports, video, sound, and other components. This application also allows the
user to run multi-threaded tests on hardware components. If problems are found,

performance and generating the following alerts:
■
■
■
■
■
Hard drive alert—provides 72-hour advance warning of impending hard drive
problems and can automatically start optional backup software.
System temperature alert—reports overheating. As the system temperature rises,
this feature first adjusts fan speed and other cooling components, then displays an
alert, then shuts down the system.
Battery pack alert—reports charging problems and battery pack failure.
Monitor alert—diagnoses and displays external monitor operational problems.
Memory alert—reports memory board configuration changes when a memory
board is removed, added, or reconfigured. It also provides the previous and current
configurations for comparison.
The alerts work with or without network connection. If the computer is not connected to
the network, the network administrator cannot receive alerts from the computer.
Fault Management Alerts
Alerts can be enabled, disabled, and tested, and software can be set to back up
information whenever a hard drive alert occurs.
■
While the computer is connected to a network, alerts pop up on the computer
display and are simultaneously reported to the network console.

1. Complete the preliminary steps listed in Section 2.1.
2. Run the Power-On Self-Test (POST) as described in Section 2.3.
3. Run Computer Setup as described in Section 2.5.
4. If you are unable to run POST or if the problem persists after running POST,
perform the recommended actions described in the diagnostic tables in Section 2.5.
Follow these guidelines when troubleshooting:
■
Complete the recommended actions in the order in which they are given.
■
Repeat POST after each recommended action until the problem is resolved and the
error message does not return.
■
When the problem is resolved, stop performing the troubleshooting steps and do not
complete the remaining recommended actions.
■
Refer to Chapter 5 for recommended removal and replacement procedures.
■
If the problem is intermittent, check the computer several times to verify that the
problem is solved.

2.1 Preliminary Steps
IMPORTANT: Use AC power when running POST or Computer Setup. A low battery
condition could initiate Hibernation and interrupt the test.
Before running POST, complete the following steps:
1. Obtain established passwords. If you must clear the passwords, go to Section 2.2.
2. Ensure that the battery pack is installed and the power cord is connected to the
computer and plugged into an AC power source.
3. Turn on the computer.
4. If a power-on password has been established, type the password and press Enter.
5. Run Computer Setup (Section 2.5). If a Setup password has been established, type
the password and press Enter.
6. Turn off the computer and all external devices.
7. Disconnect 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.
8. Use Compaq Utilities and loopback plugs in the serial and parallel connectors if you
plan to test these ports.
Follow these steps to run Compaq Utilities:
a. If you are running Compaq Utilities from the hard drive, turn on or restart the
computer. Press F10 when the cursor appears in the upper-right corner of the
screen. If you do not press F10 in time, restart the computer and try again.
If you are running Compaq Utilities from diskette, insert the Compaq Utilities
diskette in drive A. Turn on or restart the computer.
b. Press Enter to accept OK.
c. Select Prompted Diagnostics.
d. After “Identifying System Hardware” completes, select Interactive Testing and
follow the instructions on the screen.

4. Disconnect and remove the Real Time Clock (RTC) battery (Section 5.10).
5. Wait five minutes.
6. Reconnect the RTC battery.
7. Reconnect the AC Adapter. Do not reinstall the battery pack yet.
8. Turn on the computer.
NOTE: Remember to set the date and time the next time the computer is turned on.
2.3 Power-On Self-Test (POST)
The Power-On Self-Test (POST) is a series of tests that run every time the computer is
turned on. POST verifies that the system is configured and functioning properly.
To run POST, complete the following steps:
1. Complete the preliminary steps (Section 2.1).
2. Turn on the computer.
If POST does not detect any errors, the computer beeps once or twice to indicate that
POST has run successfully. The computer boots from the hard drive or from a bootable
diskette if one is installed in the diskette drive.
Troubleshooting

2.4 POST Error Messages
If the system is not functioning well enough to run POST, or if the display is not
functioning well enough to show POST error messages, refer to the Troubleshooting
tables in Section 2.6.
If POST detects an error, one of the following events occurs:
■
A message with the prefix "WARNING" appears, informing you where the error
occurred. The system pauses until you press F1 to continue.
■
A message with the prefix "FATAL" appears, informing you where the error
occurred. After the message, the system emits a series of beeps, then stops.

R EMOVAL AND R EPLACEMENT
P RELIMINARIES
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 Torx T-8 screwdriver (for all screws unless otherwise specified)
9/32-inch socket for bushing guides
4.2 Service Considerations
Listed below are some of the considerations that you should keep in mind during
disassembly and assembly procedures.
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.
IMPORTANT: As you remove each subassembly from the computer, place it (and all
accompanying screws) away from the work area to prevent damage.
Removal and Replacement Preliminaries
4-1
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 or a removable drive, or loss of information, observe these
precautions:
■
■
■
■
■
■
■
■
■
■
■
■
4-2
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, CD-ROM drive, SuperDisk LS-120 drive, or a
DVD-ROM drive, ensure that a diskette or disc is not in the drive. Ensure that the
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 that have at least one inch of shock-proof foam.
Avoid dropping drives from any height onto any surface.
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, ship it in a suitable form of protective packaging.
Shipping the drive in standard packaging may not cushion it from destructive shock,
vibration, temperature, or humidity. Place a mailing label with the wording
“Fragile: Handle With Care” on the mailer.
After the hard drive has been removed from the computer, avoid turning the hard
drive and tray upside down. The drive is not secured to the tray and can fall out.
Do not place labels on the ventilation area on the hard drive.
Heed the labels on the hard drive.
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. Or it may function
normally for a while, then degrade in the internal layers, reducing its life expectancy.
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 are selected to avoid static charging. When grounding is not
possible, use an ionizer to dissipate electric charges.

Workstation Precautions
Use the following grounding precautions at workstations:
■
■
■
■
■
■
■
■
4-4
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.
Avoid contact with pins, leads, or circuitry.
Turn off power and input signals before inserting or removing connectors or test
equipment.
Removal and Replacement Preliminaries
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, a strap must be worn snug against the skin. 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 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.
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
