Using the Mouse
The Compaq mouse comes with your computer, but any serial
PS/2 mouse may be used. The mouse controls the on-screen
pointer or cursor when you use Windows and other graphical
software.
Compaq Mouse
Most software applications that support a mouse use the four
basic mouse techniques described below:
■
Point: Move your mouse to point to your selection on the
screen.
■
Click: Press and release the left mouse button.
■
Double-Click: Press and release the left mouse button twice
(quickly).
■
Click and Drag (also called Drag and Drop): Press and
hold the left mouse button, then move the mouse. Release
the button when you finish dragging your selection.

To use the mouse:
1. Make sure the mouse is properly connected to the computer
and that the computer startup is complete.
2. Place the mouse on a clean, flat surface, such as your
desktop.
3. Move your mouse across the flat surface and a pointer
moves across your screen.
❏
To type, move the pointer to a spot on the screen
where you want to begin typing, then press and release
(this is called clicking) the left mouse button once. The
cursor will begin blinking at the spot you clicked, and
you may begin typing there.
❏
To make a selection in a program menu, use the mouse
to click on the menu name, then click on your selection
in the drop-down menu list.
❏
To open icons (small pictures that represent files and
programs), position the mouse pointer on the icon, then
double-click.
✎ The double-click speed is timed. If you double-click too
slowly, your computer responds as if you single-clicked twice.
Remember, click quickly.
Cleaning the Mouse
For the most part, a mouse cleans itself as you move it around.
However, if you find that the pointer does not move smoothly,
or that the ball does not move freely, you should clean the
mouse.
To clean the mouse, complete the following steps:
1. Turn off your computer.
2. Disconnect the mouse cable from the computer.
3. Turn the mouse upside down.
4. Remove the mouse ball cover.
5. Gently turn the mouse over and let the ball drop into your
hand.

6. Use a cotton swab dipped in isopropyl (rubbing) alcohol to
wipe the ball clean. Squeeze the excess liquid out of the
cotton swab before wiping the ball.
7. Dry the ball with a clean, lint-free cloth.
8. Blow into the ball cage to remove any dust or lint from
inside. (The cage contains rollers like those on a tape
recorder. Use a cotton swab and tape head cleaner to wipe
off any oil on these surfaces. Turn the rollers to clean all
surfaces.)
9. Put the ball back into the mouse and close the mouse ball
cover.
10. Plug the mouse cable into the computer.
Caring for Your
Computer
Follow these suggestions to protect your computer and monitor:
■
Operate the computer on a sturdy, level surface such as
a desk or table. Leave a three-inch (7.6-cm) clearance at
the back of the system unit and above the monitor to
permit required airflow.
■
Never restrict the airflow into the computer by blocking the
front vents or air intake. Do not place the keyboard, with the
keyboard feet down, directly against the front of the unit as
this will restrict the airflow.
■
Keep the computer away from excessive moisture, direct
sunlight, and extremes of heat and cold. For information
about the recommended temperature and humidity ranges
for your computer, refer to Appendix B, “Specifications.”
■
Keep liquids away from the computer and keyboard.
■
Never cover the ventilation slots on the monitor with any
type of material.

1-17
✎ For the following suggestions, be sure the computer is turned
off.
■
Clean the exterior of the computer, the monitor casing, and
the outer surfaces of the keyboard with a soft cloth
dampened with water as needed. Wipe with a soft, lint-free
cloth to remove any moisture. Using cleaning products may
discolor or damage the finish.
■
Visible debris underneath or between the keyboard keys
may be removed by vacuuming or gentle shaking.
■
Wipe the monitor screen with a clean cloth moistened with
water or with a towelette designed for cleaning monitors.
Do not use sprays or aerosols directly on the screen, as
liquid may seep into the housing and damage internal
components.
Occasionally clean the air vents on the front and back of the
computer. Lint and other foreign matter can block the vents and
limit the airflow.

Security features built into the Compaq Deskpro 2000 Series of
Personal Computers provide solutions for a variety of potential
security problems.
■
Physical security features such as the cable lock provision
help prevent theft or unauthorized access to internal
components such as processor and memory.
■
Passwords help prevent unauthorized configuration changes
and access to information stored on the computer or the
network.
■
DIMM memory module configuration changes will trigger
local and remote alert messages, providing timely notice of
unauthorized additions, changes, or removals. This feature
is supported on all Compaq DIMM memory modules and

steps:
✎ Your computer may already have the cable lock provision
installed.
1. Remove one thumbscrew from the rear of the computer.
Use a flat-bladed screwdriver if needed.
2. Separate the pieces of the security bracket by bending the
metal where the three pieces join.
3. Insert the tang of the narrow bracket into the slot and slide
the u-shaped bracket between it and the system unit cover;
then, install the self-tapping screw included in the cable
lock kit.
4. Cover the screw with the flat portion of the bracket.
5. Install a lock (not provided) to secure the top part of the
security bracket to control access to the inside of the

Fault Management
Fault Management features combine innovative hardware and
software technology to prevent the loss of critical data and
minimize unplanned downtime.
When a fault occurs, the computer displays a Local Alert
message containing a description of the fault and any
recommended actions. You can then view current system health
by using Compaq Insight Personal Edition. If the computer is
connected to a network managed by Compaq Insight Manager
or other SNMP-based management products (e.g., HP
OpenView or IBM Tivoli TME10 NetView), the computer also
sends a fault notice to the network management application.
SMART II Hard Drive Fault Prediction
The SMART II hard drive monitors hard drive activity to predict
failures before they occur. Fault prediction and failure indication
parameters, such as abnormal variations in spinup and seek
times, or non-correctable read and write errors, are tracked to
determine the hard drive condition. Should these errors become
significant, the computer displays a warning message. The
warning gives you time to back up the hard drive and replace it
prior to experiencing downtime or loss of data. The Prefailure
Warranty for SMART II hard drives allows you to replace these
drives, free of charge, before the drives fail.
SMART II hard drives are compliant with the Small Form
Factor Committee Specification for Self-Monitoring, Analysis,
and Reporting Technology (SMART) Version II. SMART is the
industry standard technology, pioneered by Compaq and
originally called IntelliSafe, that allows you to prevent data loss
and minimize downtime, in concert with Compaq Insight
Management Agents.

ECC Fault Prediction and Prefailure Warranty
When the computer encounters an excessive number of error
checking and correcting (ECC) memory errors, the screen
displays a Local Alert message. This message contains detailed
information about the errant memory module, allowing you to
take action before you experience non-correctable memory
errors. The Prefailure Warranty for ECC memory modules
allows you to replace these modules, free of charge, before the
modules actually fail. ECC memory modules are optional on all
Compaq Deskpro personal computers.
✎ To use this feature, you must replace the standard DIMMs
with ECC DIMMs.
Monitor Fault Diagnosis
Certain new Compaq monitors detect when the operating
temperature exceeds the normal range or when a hardware fault
occurs. Hardware faults may include the following:
■
Power voltage out of range
■
Power current out of range
■
Horizontal deflection
■
Vertical deflection
■
I/O controller operation failure
If the monitor detects one of these conditions, the computer will
send an alert over the network to the system administrator.
Proactive Backup
Proactive Backup software initiates a tape or PD-CD backup
upon receiving notice of an impending SMART II hard drive
failure.
The Seagate Backup Exec SMART Client works with Seagate
Backup Exec tape backup software on the server, or with
Seagate Backup Exec software supporting the PD-CD drive.
Together with the Insight Management Agents, this software
offers a Proactive Backup solution. For instructions on
configuring the Backup Exec SMART Client, contact your
systems administrator or refer to the Seagate Backup Exec
documentation.

Cheyenne has also created an agent to support the Proactive
Backup solution. The SMART Drive Agent is the component
that recognizes and reacts to the SMART II hard drive fault
alerts. This agent is an extension to the Microsoft Windows 95
tape backup agent for the standalone application ARCsolo for
Windows. This agent works with the SMART II hard drive to
ensure that critical data will be protected in the event of a hard
drive failure.
Surge-Tolerant Power Supply
An integrated, 200-watt, surge-tolerant power supply provides
greater reliability when the computer is hit with an
unpredictable power surge. This power supply is rated to
withstand a power surge of up to 2000 volts without incurring
any system downtime or data loss.
Security Management
As access to a network increases, so does the risk of
unauthorized access to critical information and theft of valuable
components. The Compaq personal computer provides a robust
set of security features to protect the computer and data from
unauthorized access.

Remote ROM Flash
Your computer comes with reprogrammable flash ROM (Read
Only Memory). By establishing a setup password in Security
Management, you can protect the ROM from being unintentionally
updated or overwritten. This is important to ensure computer
operating integrity. Should you need or want to upgrade your ROM,
you may:
■
Order an upgraded ROMPaq diskette from Compaq.
■
Order the Support Software CD for Compaq Desktop,
Portable, and Workstation Products.
■
Download the latest ROMPaq images from the Compaq
World Wide Web site (www.compaq.com).
CAUTION: For maximum ROM protection, be sure to establish a
setup password. The setup password prevents unauthorized ROM
upgrades.
Upgrading Flash ROM
To upgrade the ROM after you receive an upgraded ROMPaq
diskette, complete the following steps:
1. Insert the ROMPaq diskette in the diskette drive, enter the
correct command, and the computer will prompt for the
setup password.
2. Enter the setup password.
If the setup password is entered correctly, the ROMPaq
utility will take over and run the flash ROM upgrade.
✎ Do not turn off the power to your computer until the
ROMPaq utility has completed the upgrade process.
✎ If the setup password is incorrectly entered, the procedure
will terminate and no changes will be made to the ROM.
3. When the utility finishes upgrading the ROM, remove the
diskette from the diskette drive and restart your computer.

Using Remote ROM Flash
Remote ROM Flash allows the system administrator to safely
upgrade the ROM on remote Compaq Deskpro personal
computers, directly from the centralized network management
console. Enabling the system administrator to perform this task
remotely, on multiple computers, results in a consistent
deployment of and greater control over Deskpro ROM images
over the network. It also results in greater productivity and
lower total cost of ownership.
Compaq created the Remote ROM Flash capability to be secure
and fail-safe. All Deskpro ROMPaq ROM images from Compaq
are digitally signed to ensure authenticity and minimize
potential corruption. The ROM firmware includes a Boot Block
that is protected during the flash process and allows the Deskpro
to be restarted, in the unlikely event of an unsuccessful ROM
flash.
✎ The digitally-signed ROM functionality is only available
with Microsoft Windows 95 or Release 2 of Microsoft
Windows NT 4.0.
Remote ROM Flash is performed in two stages:
1. System administrator uses the Remote Management Setup
software on a centralized management console to prepare a
Deskpro ROMPaq file.
2. System administrator uses a PC LAN management product,
such as Microsoft SMS, Intel LANDesk Manager, or
Symantec Norton Administrator for Networks, to distribute
and execute the file over the network to remote Deskpros.
✎ The Deskpro 2000 must be powered on to take advantage
of Remote ROM Flash.
Use of Remote ROM Flash requires an established setup
password.
For more information on enabling Remote ROM Flash, refer to
the online Remote Management Administrator’s Guide.

FailSafe Boot Block ROM
The FailSafe Boot Block ROM allows for system recovery in
the unlikely event of a ROM flash failure, for example, if a
power failure occurs during a ROM upgrade. The Boot Block is
a flash-protected section of the ROM that checks to validate the
system ROM each time power to the system is turned on.
■
If the system ROM is valid, the system starts normally.
■
If the system ROM fails the validation check, the FailSafe
Boot Block ROM provides enough support to start the
system from a ROMPaq diskette, which will program the
system ROM with a valid image.
Because there is no video or hard drive support from the Boot
Block ROM, the keyboard lights communicate information.
When the Boot Block detects an invalid system ROM, the
system sounds a series of beeps (one long and three short) and
flashes the three keyboard lights.
To recover the system after hearing the FailSafe Boot Block
beeps, complete the following steps:
1. Remove any diskettes from the diskette drive and turn off
the power.
2. Insert a ROMPaq diskette into the diskette drive.
3. Turn on power to the system.
If a setup password has been established, the Caps Lock
light will turn on.
4. Enter the setup password.
When the system successfully starts from the diskette and
reprograms the ROM, the three keyboard lights will turn on.

Using the Cable-Select Feature with Ultra ATA Devices
Optional drives are available from Compaq in kits that include a
special drive cable. The configuration of the drives employs a
cable-select feature that identifies the drives as device 0
(primary drive) or device 1 (secondary drive). The system board
determines which drive is device 0 or device 1, based on the
way the drives are connected to the special drive cable. The
device 0 drive is the drive connected to the short segment of the
drive cable (or that connector closest to the system board); the
device 1 drive is the drive connected to the long segment of the
drive cable. The device 0 and device 1 identities are used by the
system to distinguish between the two drives.
The installation requires no jumper setting changes on the
existing or optional drives. All Compaq drives have the jumpers
preset for cable-select installation.
✎ If installing a second device on the primary controller,
you must use an 80-conductor Ultra ATA cable for
optimal performance. This cable is available as a Compaq
option.
Installing a 5.25-Inch Drive into a 5.25-Inch Drive Bay

Using the Cable-Select Feature with Ultra ATA Devices
Optional drives are available from Compaq in kits that include a
special drive cable. The configuration of the drives employs a
cable-select feature that identifies the drives as device 0
(primary drive) or device 1 (secondary drive). The system board
determines which drive is device 0 or device 1, based on the
way the drives are connected to the special drive cable. The
device 0 drive is the drive connected to the short segment of the
drive cable (or that connector closest to the system board); the
device 1 drive is the drive connected to the long segment of the
drive cable. The device 0 and device 1 identities are used by the
system to distinguish between the two drives.
The installation requires no jumper setting changes on the
existing or optional drives. All Compaq drives have the jumpers
preset for cable-select installation.
✎ If installing a second device on the primary controller,
you must use an 80-conductor Ultra ATA cable for
optimal performance. This cable is available as a Compaq
option.

EPA Energy Star Compliance
Compaq Deskpro 2000 Series of Personal Computers marked
with the Energy Star Logo are compliant with the U.S.
Environmental Protection Agency (EPA)’s Energy Star
Computers Program 2.0. The EPA Energy Star Logo does not
imply endorsement by the EPA. As an Energy Star Partner,
Compaq Computer Corporation has determined that the
products marked with the Energy Star Logo meet the Energy
Star guidelines for energy efficiency.
The Energy Star Computers Program was created by the EPA to
promote energy efficiency and reduce air pollution through
more energy-efficient equipment in homes, offices, and
factories. Compaq products achieve this by reducing the power
consumption when not being used. Instructions for using the
energy saving features of your computer are located in the
power management section of this guide.
The power management feature of your computer is supported
when used with the following operating systems: DOS,
Windows, Windows NT, and Windows 95.
The power management feature of your computer is compatible
with network environments. This means, the user will not be
disconnected from the network during the low-power operating
state. The following network environments are supported:
NetWare, Windows 95, Windows NT, Banyan.
The power management feature, when used in conjunction with
an external Energy Star compliant monitor, will support the
power down features of the monitor. The power management
feature allows an external monitor to go into low-power mode
when the screen save timeout occurs. To take advantage of this
energy savings, the monitor power management feature has
been preset to power down the monitor after 15 minutes of
system inactivity. Refer to the Power Management or Energy
Saver section of this guide for instructions on modifying or
disabling this feature.
CAUTION: Using the Energy Save Monitor feature with non-Energy
Star compliant monitors may cause video distortion when the
Screen Save timeout occurs.

This section provides information for setting DIP switches after
upgrading the processor and for setting jumpers to
enable/disable passwords or clear the configuration memory
(CMOS).
✎ To change the system board jumpers, you must remove the
computer cover. For procedures on removing the computer cover,
refer to Chapter 5, "Upgrading Your Desktop Computer," or
Chapter 6, “Upgrading Your Minitower Computer.”
!
WARNING: To reduce the risk of personal injury from hot
surfaces, allow the internal system components to cool before
touching.
CAUTION: Be sure to turn off the computer before changing a
jumper setting or damage to the system board can result.

Setting Power-On
Password Jumpers
If you forget your Power-On Password, you will need to disable
it by setting the appropriate jumper on the system board.
1. Locate the appropriate jumper. For Pentium systems, this
jumper is labeled E6. For Pentium II systems, it is labeled
P2. By default, the Power-On Password is enabled,
meaning there is a plug on pins 5 and 6.
Locating the E6 Jumper on the Pentium System Board
Locating the P2 Jumper (Pins 5-7) on the Pentium II System Board
2. To disable the Power-On Password, move the plug from
pins 5 and 6 to pins 6 and 7.
3. To set a new Power-On Password, put the plug from pins 6
and 7 to pins 5 and 6, then reestablish the password using
the Security Management feature in Computer Setup.

Clearing
Configuration
Memory
The computer's configuration memory (CMOS) may
occasionally be corrupted by static electricity. This happens
very rarely. When it does occur, it is usually due to software or
hardware that is not executing accurately or by adding or
removing expansion boards to or from the computer. If the
computer's configuration memory becomes corrupted, it is
necessary to clear the configuration memory.
To clear and reset the configuration memory:
✎ Be sure your computer is powered off before beginning this
procedure.
1. Locate the appropriate jumper. For Pentium systems, this
jumper is labeled E8. For Pentium II systems, it is labeled
P2.
2. Remove the plug from pins 1 and 2, place it on pins 2 and
3, then return it to pins 1 and 2.

3. Replace the cover and tighten the thumbscrews on the rear
panel.
4. Turn the computer on.
5. Run the Computer Setup utility to reconfigure the system.
Refer to Chapter 3, "Using Compaq Utilities." If the system
configuration is incorrect, your computer may not work
properly and you may receive error messages on the screen.
✎ When the CMOS jumper is removed, your password will become
invalid because the password is stored in the configuration
memory. You will need to reset your password.

S HIPPING Y OUR C OMPUTER
To prepare the computer for shipping, follow these guidelines:
1. Back up the hard drive files onto diskettes (or onto an
external hard drive or other external storage device, if

E LECTROSTATIC D ISCHARGE
A discharge of static electricity from a finger or other conductor
may damage system boards or other static-sensitive devices.
This type of damage may reduce the life expectancy of the
device.
Preventing
Electrostatic
Damage
To prevent electrostatic damage, observe the following
precautions:
■
Avoid hand contact by transporting and storing products in
static-safe containers.
■
Keep electrostatic-sensitive parts in their containers until
they arrive at static-free workstations.
■
Place parts on a grounded surface before removing them
from their containers.
■
Avoid touching pins, leads, or circuitry.
■
Always be properly grounded when touching a staticsensitive component or assembly.
Grounding Methods
There are several methods for grounding. Use one or more of
the following methods when handling or installing electrostaticsensitive parts:
■
Use a wrist strap connected by a ground cord to a grounded
workstation or computer chassis. Wrist straps are flexible
straps with a minimum of 1 Mohm +/- 10 percent resistance
in the ground cords. To provide proper ground, wear the
strap snug against the skin.
■
Use heelstraps, toestraps, or bootstraps at standing
workstations. Wear the straps on both feet when standing on
conductive floors or dissipating floor mats.

I NSTALLING A N EW B ATTERY
When your computer no longer automatically displays the correct
date and time, it may mean the battery providing power to the realtime clock needs to be replaced. Battery life is usually about five to
ten years under normal use. Use Compaq replacement battery
160274-001 or a comparable 600-milliamp alkaline, 4.5-volt battery.
✎ It is important to make a set of backup diagnostics diskettes before
you install a new battery.
✎ If you are using a non-Compaq hard drive, it is important to take
the following steps before installing the battery.
1. Run the Computer Setup utility and observe the drive type
that is displayed in the System Configuration summary.
2. If the drive type number is 65 or 66, make a note of the
drive parameters (cylinders, heads, sectors per track). You
can view these parameters using Computer Setup (Built-In
Devices, Storage) or Compaq Enhanced Insight Personal
Edition (Diagnostics for Windows). Refer to Chapter 3,
"Using Compaq Software, for more information on using
these utilities. It is important to record these parameters on
paper before continuing.
3. When you have completed the battery installation, you may
need to run Computer Setup and use the drive parameters
noted earlier to reconfigure your system.
To install the new battery, complete the following steps:
✎ Do not attempt to remove your old battery as it is permanently
installed.
1. If your computer is on, turn it off.
2. Unplug the computer and disconnect any external devices.
