1-14 Computer at a Glance

The keyboard has feet on the bottom that enable the user to tilt the keyboard to a more comfortable typing angle.

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.

Reference Guide 1-15

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.

1-16 Computer at a Glance

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.

Reference Guide 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.

PROTECTING INFORMATION ON THE COMPUTER

Security Features

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 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.

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

QuickLock/QuickBlank lets you disable the keyboard and mouse interface and optionally blank the screen while applications are running.

Reference Guide 2-1

Physical Security

The cable lock provision can be used with a padlock to help prevent theft or unauthorized access to internal components such as processor and memory. For additional security, the cable lock provision can be used with a cable and padlock to secure the computer to a fixed object.

Installing the Cable Lock Provision

To install the cable lock provision, complete the following 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 computer. Install a cable lock (not provided) to secure the computer to a fixed object.
