Introduction to the User’s Guide

The User’s Guide includes general information about your computer, troubleshooting, upgrades, diagnostics information, and technical specifications.

Your Compaq computer comes with Windows 98 already installed on the hard drive. After you set up your computer according to the Setup Poster, refer to “Setting up Your Software” in the Getting Started Guide for a screen-by screen description of software setup on your Compaq computer. If you are already familiar with the setup process, you should still refer to the hints in this section prior to beginning the process.

You will need the following information during the setup process:

■ Regional settings (the language you want to use during the setup

process). Your software language is determined by the product that you ordered.

■ Information about your name and company

■ Product Key number from the Certificate of Authenticity

✎ You will find the Product Key printed in a bar code on your

Certificate of Authenticity, which appears on the front of the Windows 98 booklet that came with your computer.

Your time zone, the date, and the time

■

User’s Guide 1–1

Throughout the setup process, follow these hints:

■ Always use the left mouse button during the selection process.

■ Do NOT install a printer, printer drivers, or any other type of

drivers until AFTER the initial setup process is complete. Attempts to do so will disrupt the setup process.

CAUTION: Installing a printer may disrupt the setup process. Aviod printer installation until after the initial setup process is complete.

■ If you get a Printer Install screen, select Cancel.

■ Prior to or during the setup process, do not attempt to install

additional software or to attach any external devices or drives (such as printers and ZIP drives, or printer drivers on CD).

■ Once the setup process begins, do not interrupt the process, turn

the power off, or bump or unplug the power cord. If the process is abruptly stopped or interrupted, you may have to install the system using the Quick Restore CD, which will take longer.

■ If the screen goes blank or nothing appears to be happening, look

at the drive activity light or the screen for an hourglass. If lights are blinking or you see an hourglass, the setup process is continuing. If the computer locks up for more than one hour and will not continue the setup process, restart the computer to continue setup. Turn the computer off by pressing the Power button. Do not use Ctrl+Alt+Del to turn off your computer.

DVD-ROM Problems

Problem Possible Cause Solution

✎

This feature is not currently available for Windows NT.

Certain files on a DVD disk will not play using the MediaPlayer

A DVD disk inserted in the DVDROM drive with DVD Player running will not play

The MediaPlayer does not initiate the authentication process necessary for playback of DVD files. Attempts to play these files will result in no video being played.

In the drivers for most DVD-ROM drives there is an Auto-Insert Notification option that is turned on by default. This option lets the operating system know when a DVD or compact disk is inserted into the DVD-ROM drive. The purpose of the feature is to begin running software or to begin playback of a disk when it is first inserted into the drive without the need for running an application.

If this option is turned off, the DVD Player application does not know that you inserted a DVD disk.

Use the DVD Player to play all content. This is the correct way to view all DVD files.

To turn this option on, use the following procedure:

1. Click Start→Settings→Control Panel.

2. Double-click the System icon; then select the Device Manager tab.

3. Locate the CD-ROM listing, and click the entry for your DVDROM drive.

4. Click the Properties button and then the Settings tab.

5. Locate and click the checkbox labeled Auto Insert Notification.

6. Click OK to save the change.

7. Restart Windows 98, if necessary, for the change to become active.

Hard Drive Problems

Problem Possible Cause Solution

CAUTION: Reformatting the hard drive erases all of your files permanently; be sure to make backup diskettes of your information before reformatting the drive. Compaq also recommends that you have a backup of your pre-installed software before reformatting the hard drive.

Hard drive error occurs The hard drive has bad sectors

or has failed.

If you are running Windows 98, press Start→Programs→Accessories→ System Tools→ScanDisk. Place a check in the Automatically Fix Errors box. Start the ScanDisk utility.

Modem/Fax Problems

If you have installed a modem, and are experiencing problems, this section may provide helpful information. Be sure to refer also to the documentation that came with your modem.

The following factors may affect the modulation speed at which your computer communicates:

■ The maximum communication speed of a call is determined by

the speed of the slowest modem on the connection. Many modems automatically negotiate the fastest possible speed with the modem you dial.

■ Phone line conditions may affect the speed at which your modem

actually communicates on any call. Many modems are designed to establish a reliable connection automatically at a lower speed, if required, to overcome noise or other problems with the phone line.

If you are unable to resolve a problem, contact your modem manufacturer or supplier.

2. Connect a telephone to the jack, pick up the headset, and listen for a dial tone. If there is a dial tone, reconnect the modem to the telephone wall jack with the telephone cable and make sure all connections are secure. If there is still no dial tone, contact your local phone company or building manager.

Plugging the modem into a digital line results in no dial tone. Reconnect the modem cable to an analog phone jack; then reestablish the connection.

Verify that the modem and your computer are connected.

1. Click Start→Programs→ Accessories→HyperTerminal.

2. Go to Terminal Mode; then type AT and press Enter.

3. If the modem displays OK, the modem and your computer are working together. If the modem displays ERROR or does not respond, restart your computer and repeat Steps 1 and 2.

Installing Additional Drives

Using the Cable-Select Feature with Ultra ATA Devices

The computer supports up to two drives that may be installed in various configurations. When installing additional drives, follow these guidelines:

■ For optimal performance, connect hard drives to the primary

controller. Connect expansion devices, such as CD-ROM and diskette drives, to the secondary controller.

■ You may install either a third-height or a half-height drive into a

half-height bay.

Optional drives with special drive cables are available in kits from Compaq. The drive configuration uses a cable-select feature that identifies the drives as Device 0 (primary drive) or Device 1 (secondary drive).

The Device 0 drive is connected to the short segment of the drive cable (or that connector closest to the system board); the Device 1 drive is connected to the long segment of the drive cable.

Drive installation requires that no jumper settings change on the existing or optional drives. All Compaq drives have the jumpers preset for cable-select installation.

✎ If installing a second drive on the primary controller, you must use

an 80-conductor Ultra ATA cable for optimal performance. This cable is available as a Compaq option.

Electrostatic Discharge

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

Grounding Methods

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 static-sensitive

component or assembly.

There are several methods for grounding. Use one or more of the following methods when handling or installing electrostatic-sensitive 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 megohm +/- 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.

User’s Guide C–1

Use conductive field service tools.

■

■ Use a portable field service kit with a folding static-dissipating

work mat.

If you do not have any of the suggested equipment for proper grounding, contact your Compaq authorized dealer, reseller, or service provider.

✎ For more information on static electricity, contact your Compaq

authorized dealer, reseller, or service provider.
