Using the Mouse

Keyboard Tilt Foot

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.





Caring for Your

Computer

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.

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.





✎

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.

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.

■

■

Physical security features such as the cable lock provision help prevent theft or unauthorized access to internal components such as processor and memory.

Setup and Power-On Passwords help prevent unauthorized 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 others that comply with the DIMM Serial Presence Detect

(SPD) standard.

The Ownership Tag displays ownership information during system restart. The Ownership Tag information can be entered or modified in Computer Setup and is protected by the Setup Password.

Drive and media security features control access to the information stored on the computer and can prevent unauthorized transfer of data to a diskette drive or other removable storage media (e.g., floppy, LS-120, PD-CD).

These features can also prevent startup from the removable media drives.

Device disabling features can prevent unauthorized transfer of data over fax/modems, serial ports, parallel ports, or infrared ports.

QuickLock and QuickBlank can be set to lock the keyboard and/or blank the monitor screen when the PC goes into low power mode.

Security management settings can be viewed locally using

Compaq Insight Personal Edition or remotely using Compaq

Remote ROM Flash

Remote Security Management

Replicated Setup

■

Enhanced Support Software CD and World Wide Web

Site

✎

Use of remote Configuration Management features requires an established setup password.





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.





The following table lists the various keyboard light combinations, as well as the meaning and action associated with each combination.

Installing an

Additional Drive

When installing a new drive you should use either the high hat screws provided in the option kit or the extra U.S. and metric screws stored in the front of the computer chassis for this purpose. The same screws that are used as guide screws are used as retainer screws to secure the drive in the drive bay.

Select the appropriate screws for the application.

✎

Metric screws have a black finish while U.S. screws have a silver finish.

Locating the Mounting Screws

✎

Compaq strongly recommends that only an authorized service provider replace your primary hard drive.






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.

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.

Locating the E8 Jumper on the Pentium System Board

Locating the P2 Jumper (Pins 1-3) on the Pentium II System Board





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.

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 available). To prevent data loss, do not expose your backup diskettes to electrical or magnetic impulses.

2. Remove all diskettes from the the diskette drives; remove the CD from the CD-ROM drive, if any.

3. Turn off the computer and external devices.

4. Disconnect the power cord from the electrical outlet, then from the computer.

5. Disconnect your printer and any other external devices from their power sources, then from the computer.

✎

Make sure all boards are seated properly in the expansion slots with their retaining screws in place before shipping the computer.

6. Pack the computer in its original packing box or in similar packaging with sufficient packing material to protect it.

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.

Reference Guide G-1

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.
