Identifying Your Computer

Preparing Your Computer for Travel

Travel Tips

Identifying Your Computer

As an antitheft measure, assign a primary password and a hard-disk drive password to prohibit unauthorized access to the computer.

Dell recommends that you follow these precautions before you travel with your computer:

Write down your service tag and put it in a safe place separate from the computer or carrying case. If the computer is lost or stolen, use the service tag number when reporting

to law enforcement officials and to Dell.

●

Use a text editor (such as Microsoft® Windows® Notepad) to create a file called if_found in your root directory. Place information such as your name, address, and telephone number in this file. (For instructions on using the appropriate text editor, see the documentation that came with your operating system.)

●

Attach your business card or other name tag to the computer.●

Contact your credit-card company and ask if it offers coded identification tags that allow your property to be returned to you without the risk of revealing your name, address, or telephone number.

●

Use a permanent marking or stenciling device to write your driver’s license number or some other unique identifying mark on the computer. If a lost or stolen computer is recovered, such marking identifies the computer as your property.

●

Service Tag

The service tag is an alphanumeric sequence on a bar code label located on the bottom of the computer. The service tag is unique to your computer and allows Dell technical assistance

Traveling With Your Computer: Dell Latitude LS Portable Computers User's Guide

file:///C|/Documents and Settings/Administrator/De...ew Web/Documentation/LS/LS User's Guide/travel.htm (1 of 5) [5/31/2000 9:43:18 AM]

Page 15

personnel to identify the computer and its configuration quickly if you call for assistance.

If Your Computer Is Lost or Stolen

If your computer is lost or stolen, Dell suggests that you perform the following steps:

Call a law enforcement agency to report the lost or stolen computer.1. Include the service tag in your description of the computer. Ask that a case number

be assigned, and write it down. Also write down the name, address, and telephone number of the law enforcement agency. If possible, obtain the name of the investigating officer.

If you know where the computer was lost or stolen, call a law enforcement agency in that area. If you do not know, call a law enforcement agency where you live.

If the computer belongs to a company, notify the security office of the firm.2.

Call Dell technical assistance to report the missing computer.3. Provide the computer’s service tag, the case number, and the name, address, and

telephone number of the law enforcement agency to which you reported the missing computer. If possible, give the name of the investigating officer.

The Dell support technician will log your report under the computer’s service tag and flag the computer as missing or stolen. If someone calls Dell for technical assistance and gives your service tag, the computer is identified automatically as missing or stolen. The technician will attempt to get the phone number and address of the caller. Dell will then contact the law enforcement agency to which you made the report of the missing or stolen computer.

Preparing Your Computer for Travel

To prepare your computer for travel, perform the following steps:

Detach any external devices attached to the computer, and store them in a safe place. Remove any cables attached to installed PC Cards (you do not have to remove the PC Card itself).

To maximize battery life, check the charge on your battery. Then fully charge the battery and any spares you plan to carry with you. For more information, see "Batteries."

For systems running Windows 95, turn off the computer or press <Fn><a> to enter

suspend-to-disk (S2D) mode. (On a French keyboard, press <Fn><q>.) For systems

running Windows 98, turn off the computer.

NOTICE: When you disconnect the AC adapter from the computer, grasp the adapter cable's connector, not the cable itself, and pull gently but firmly to avoid damaging the

cable.

Disconnect the AC adapter.4.

NOTICE: When the display is closed, items left on the keyboard could damage the display.

Make sure that there is nothing on the keyboard and palmrest that can damage the display when you close it. Then close the display.

Pack all your computing accessories.6. With an optional Dell carrying case, you can pack the computer and its accessories

together. A lightweight portfolio travel case without storage space is also available.

NOTE: Follow the travel tips and take special precautions if you are planning to travel by air.

Accessories

You may want to take some of the following accessories with you when you travel:

Spare batteries

●

Cables for PC Cards (if necessary)●

AC adapter and AC power cable●

Power adapters for foreign electrical outlets and modem cable adapters for foreign telephone networks

●

Appropriate printer driver files if you will be using a printer●

External media bay and its cable●

Additional storage devices such as the CD-ROM and diskette drives●

Backup diskettes●

Dell System Software CD●

Traveling by Air

You may want to take the following precautions when you are traveling by air with your computer:

Notify airport security in advance that you are bringing a portable computer.

●

Traveling With Your Computer: Dell Latitude LS Portable Computers User's Guide

file:///C|/Documents and Settings/Administrator/De...ew Web/Documentation/LS/LS User's Guide/travel.htm (3 of 5) [5/31/2000 9:43:18 AM]

Page 17

Be sure to have a charged battery or the AC adapter and power cable available in case you are asked to turn on the computer.

●

Do not check the computer as baggage.●

NOTICE: Have airport security personnel check the computer by hand. If the computer passes through a metal detector, data loss may occur. If you must pass the computer through a metal detector, first remove the hard-disk drive.

Do not put the computer through a metal detector. (The computer can safely go through an airport X-ray security machine.)

●

Before you use the computer on an airplane, check the in-flight magazine or ask the flight crew to verify that such use is permitted. Some airlines forbid the use of electronic devices during the flight. All airlines forbid the use of electronic devices during takeoff and landing.

●

Use a carrying case (available from Dell) to protect the computer and accessories during travel.

●

If you pack the computer in a suitcase, do not pack so tightly that the computer display breaks or so loosely that the computer slides around.

●

Avoid packing the computer with items such as shaving cream, colognes, perfumes, or food.

●

Protect the computer, the battery, and the hard-disk drive from hazards such as extreme temperatures; overexposure to sunlight; and exposure to dirt, dust, or liquids.

●

Pack the computer so that it does not slide around in the trunk of your car or in an overhead storage compartment.

●

If you are carrying a hard-disk drive separately from your computer, protect the drive from exposure to static electricity by placing it in the case you received it in or in an antistatic bag, or wrapping it in a nonconductive fabric.

●

NOTICE: Carefully handle the hard-disk drive only by its carrier; do not touch the drive itself. The drive comes in a metal carrier for protection and easy installation. The drive is vulnerable to static electricity and scratches when outside the computer because the drive carrier protects only the sides of the drive, leaving the top and bottom of the drive exposed.

Travel Tips

Consider changing the settings of your power management options to maximize battery life if you will be using battery power for extended periods.

●

If you are traveling internationally, carry proof of ownership to speed your passage through customs. If the computer is provided by your employer, carry documentation of your right to use the computer. Investigate the customs regulations of the countries you plan to visit, and consider acquiring an international carnet from your government if you

travel through many different countries.

●

Power interruptions can occur frequently in some countries. Always have a charged battery available if traveling abroad.

●

Credit card holders should check with their credit card companies for information about the kinds of emergency travel assistance they offer to users of portable computers. Many companies provide services that help you solve problems, such as quickly locating

3.5-inch diskettes or providing a direct-dial telephone line for your modem connection.

●

NOTICE: Do not use a device in the external media bay while the computer is in motion. Doing so could interrupt the flow of data between the device and the hard-disk drive.

Carnet

A carnet is an international customs document (also known as a merchandise passport) that facilitates temporary imports into foreign countries and is valid for up to 1 year.

Replacing the Hard-Disk Drive: Dell™ Latitude™ LS Portable Computers User's Guide

Read the following notices carefully before attempting to replace your hard-disk drive:

NOTICE: To prevent data loss, turn off your computer before you remove the hard-disk drive. Do not remove the hard-disk drive if the computer is in suspend (or standby)

mode or if the drive access indicator is lit. Removing the drive under these conditions will lead to loss of data.

NOTICE: Hard-disk drives are extremely fragile and must be handled carefully to avoid damage. Follow these guidelines:

Handle the hard-disk drive only by its carrier; do not touch the drive itself. The drive comes in a metal carrier for protection and easy installation. The drive is vulnerable to static electricity and scratches when outside the computer because the drive carrier protects only the sides of the drive, leaving the top and bottom of the drive exposed.

●

Never press down on the top of the drive.

●

Do not drop the drive. Even a slight jar or bump can damage the drive heads and spinning plates, thus rendering the drive inoperable.

●

CAUTION: The hard-disk drive may be hot to the touch under extreme environmental conditions. If the drive is hot, allow it to cool before you replace it.

To replace a hard-disk drive, perform the following steps:

Save any open files, turn off the computer, and remove the system battery (see step 3 in "Replacing the Battery").

NOTICE: To avoid scratching the top of the computer, make sure that your work surface is clean. You may want to put down a protective mat before turning over the computer.

NOTICE: When the hard-disk drive is not in the computer, protect the drive by following the guidelines at the beginning of this section.

Remove the old hard-disk drive carrier assembly from the drive bay.2. Close the display and turn the computer over. Using a #0 (very small) Phillips-head

screwdriver, remove the two screws that secure the drive carrier assembly (see Figure 1). Save the screws for use later in this procedure.

With the computer still upside-down, press down on the drive carrier assembly's three grip lines and pull the assembly straight out to the side to remove it.

Figure 1. Removing a Hard-Disk Drive

Remove the new hard-disk drive carrier assembly from its packaging.3. Save the original packaging to use when you store or ship the hard-disk drive.

NOTICE: If the hard-disk drive carrier assembly does not slide in easily, pull it out and try again. To avoid damage, do not force the drive carrier assembly into the bay.

Install the new hard-disk drive in the computer.4. Insert the hard-disk drive carrier assembly into the drive bay, connector first and label

facing down (toward the top of the computer). Push the assembly straight in until it snaps into place, with the assembly flush with the computer case.

Replace the screws you removed in step 2. Be careful not to overtighten the screws.5.

If you have installed a new hard-disk drive, follow the directions that came with the drive to partition and logically format the drive and to create a suspend-to-disk (S2D) file.

Preparing a New Primary Drive

Every primary hard-disk drive must be physically formatted, partitioned, and logically formatted before it can be used to store data. Every primary hard-disk drive from Dell is physically formatted before it is sent to you. Use the program(s) provided by your operating system to

Information

When to Use the Dell Diagnostics How to Use Dell Diagnostics

Starting the Dell Diagnostics

Overview

Unlike many diagnostic programs, the Dell Diagnostics helps you check your computer's hardware without any additional equipment and without destroying any data. By using the diagnostics, you can have confidence in your computer's operation. And if you find a problem you cannot solve by yourself, the diagnostic tests can provide you with important information you will need when talking to Dell's service and support personnel.

NOTICE: Use the Dell Diagnostics to test only your Dell computer. Using this program with other computers may cause incorrect computer responses or result in error messages.

Features of the Dell Diagnostics

The Dell Diagnostics provides a series of menus and options from which you choose particular test groups or subtests. You can also control the sequence in which the tests are run. The diagnostic test groups or subtests also have these helpful features:

Options that let you run tests individually or collectively

●

An option that allows you to choose the number of times a test group or subtest is repeated● The ability to display or print out test results, or to save them in a file● Options to temporarily suspend testing if an error is detected, or to terminate testing when an adjustable error limit is reached● A Devices menu that briefly describes each test and its parameters● A Config menu that describes the configuration of the devices in the selected device group● Status messages that inform you whether test groups or subtests were completed successfully● Error messages that appear if any problems are detected●

When to Use the Dell Diagnostics

Whenever a major component or device in your computer does not function properly, you may have a component failure. As long as the microprocessor and the input and output components of your computer (the display, keyboard, and diskette drive) are working, you can use the Dell Diagnostics. If you are experienced with computers and know what component(s) you need to test, simply select the appropriate diagnostic test group(s) or subtest(s). If you are unsure about how to begin diagnosing a problem, read the rest of this section.

Starting the Dell Diagnostics

Perform the following steps to start the diagnostics.

NOTE: Before booting from the Dell System Software CD, you may want to print this section so that you can refer to it while running the diagnostics.

Turn off the computer.1.

Undock the computer if you have it docked.2.

Turn on the computer and press <F2> as soon as you see the Dell logo screen. If you wait too long and the operating system begins to load into memory, let the computer complete the load operation. Then shut down the system and try again.

NOTE: The options displayed on your screen should reflect the hardware configuration of your computer.

Figure 2. Dell Diagnostics Main Screen

Confirming the System Configuration Information

When you boot your computer from the Dell System Software CD, the diagnostics checks your system configuration information and displays it in the Device Groups area on the main screen.

The following sources supply this configuration information for the diagnostics:

The system configuration information settings (stored in nonvolatile random-access memory [NVRAM]) that you selected while using the system setup program

●

Identification tests of the microprocessor, the video controller, the keyboard controller, and other key components●

Basic input/output system (BIOS) configuration information temporarily saved in RAM●

Do not be concerned if the Device Groups area does not list the names of all the components or devices you know are part of your computer. For example, you may not see a printer listed, although you know one is attached to your computer. Because your printer is a parallel communications device, the computer recognizes the printer by its LPT1 address and identifies it as a parallel port. You can test your printer connection in the Parallel Ports tests.

AC Adapter: Dell™ Latitude™ LS Portable Computers User's Guide

Using the AC Adapter

Connecting the AC Adapter

Turning On the Computer

Using the AC Adapter

The AC adapter converts AC power from an electrical outlet to the DC power used by the computer. The AC adapter kit includes the AC adapter with its attached DC cable (which connects to the computer) as well as an AC power cable that connects the adapter to an electrical outlet.

You can connect the AC adapter with your computer either turned on or off. The AC adapter works with electrical outlets worldwide. However, power connectors vary

among countries. Before you use AC power in a foreign country, you may need to obtain a new power cable designed for use in that country.

If the computer is docked to the Dell Latitude LS Advanced Port Replicator (APR), it obtains power through the APR, which must be connected to an electrical outlet through the AC adapter.

NOTE: If you are running your computer on AC power with a battery installed, the AC adapter charges the battery (if needed) and then maintains the battery's charge.

NOTICE: The AC adapter should be in a ventilated area, such as on a desktop or on the floor, when used to power the computer or charge the battery. Do not use the AC adapter in a poorly ventilated environment, such as inside a carrying case.

Connecting the AC Adapter

Connect the AC adapter's attached cable into the computer's AC adapter connector (see

Figure 1).

Plug the AC adapter power cable into the other end of the AC adapter.2.

About the Batteries

Your computer includes a 4-cell or 6-cell lithium ion battery that provides power when an electrical outlet is not available. The battery is installed on the underside of the computer and forms part of the bottom of the computer. Lithium ion batteries are longer lived than conventional batteries and do not require replacement as often. You do not need to drain a lithium ion battery completely before recharging it.

Do not place spent batteries with common household waste products. See Battery Disposal for more information.

Keep the following information in mind when you are running your computer from the battery:

A fully charged 6-cell, 34-watt-hour (WH) battery provides approximately 2 hours of battery life; a fully charged 4-cell, 23-WH battery provides approximately 1 hour of battery life. Actual performance varies, depending on which power management features are enabled and which application programs you are using.

●

The integrated battery charge gauge lets you check the charge status of an installed or uninstalled battery at any time.

●

The battery’s self-test capability alerts you to battery conditions such as low charge.●

Batteries: Dell Latitude LS Portable Computers User's Guide

file:///C|/Documents and Settings/Administrator/De...w Web/Documentation/LS/LS User's Guide/battery.htm (1 of 9) [5/31/2000 9:46:08 AM]

Page 44

NOTE: If the battery is totally drained the alert functions will not operate.

You can charge the battery whenever you like without fear of reducing its charge capacity.

●

A battery has a life span of up to 350 full charges and 2000 partial charges, provided it is charged at normal room temperature.

●

Using the Battery

The battery is partially charged when you receive it. Dell recommends that you charge your battery to full capacity before using it to power the computer.

If you are powering the computer from a battery, try to conserve battery power. A number of factors affect battery operating time:

Power conservation features that you use

●

Type of display and microprocessor installed● Brightness setting of the display

●

Use of storage media

●

Number and type of external devices and type of PC Cards that you use●

NOTE: You can extend battery life by removing PC Cards when they are not being used.

Kinds of application programs that you run

●

Capacity of the memory module installed (the higher the capacity, the more power used)●

When you activate suspend mode (known as standby in the Microsoft® Windows® 98 operating system), the computer can remain in suspend mode on battery power for

approximately one week (if the battery was fully charged before activating suspend or standby mode).

If you are going to store the computer, disconnect all devices and turn off the computer. Remove the battery when you store your computer for an extended period of time. A battery will drain when not in use during prolonged storage. After a long storage period, recharge the battery fully before you attempt to run your computer from battery power.

Batteries: Dell Latitude LS Portable Computers User's Guide

file:///C|/Documents and Settings/Administrator/De...w Web/Documentation/LS/LS User's Guide/battery.htm (2 of 9) [5/31/2000 9:46:08 AM]

Page 45

NOTE: To extend battery life, store batteries at room temperature.

Charging the Battery

Each time you connect the computer to an electrical outlet or install a battery in a computer that is connected to an electrical outlet, the computer checks the battery's charge. The AC adapter charges the battery (if needed) and then maintains the battery's charge.

NOTE: For maximum battery performance, charge the battery only at room temperature.

The battery status indicator (see Figure 1) turns orange while the battery is charging and then turns green when the charge cycle is complete. It takes about 1.5 hours to completely charge

the battery, whether the computer is turned on or off.

Figure 1. Battery Status Indicator

Battery status indicator

NOTE: You can leave the battery in the computer as long as you like. The battery's integrated circuitry prevents the battery from overcharging.

Charging a Hot Battery

If your battery is hot from being used in your computer or being in a hot environment, take note of the following precautions:

A hot battery will not charge when you connect the AC adapter to the computer. This safety feature is important because charging a hot battery shortens the battery’s life span

●

and may damage the battery and the computer.

If the computer is not allowed to return to room temperature, the battery stops charging before it reaches its full capacity.

●

Replacing the Battery

To replace a battery in the battery bay, perform the following steps (see Figure 2).

NOTES: If necessary, print these instructions for reference before proceeding. Dell recommends that you turn the computer off before replacing the battery. If you want to replace the battery while the computer is running, you must first connect

the computer to an electrical outlet or enter suspend (or standby) mode or

suspend-to-disk (S2D) mode. You cannot replace the battery while the computer is

running on battery power.

If the computer is docked, undock it. (See the documentation that came with your docking device.)

NOTICE: If you choose to replace the battery with the computer in suspend (or standby) mode, you have up to 2 minutes to complete the battery replacement.

Connect the computer to an electrical outlet and then preserve your data in one of the following ways:

Place the computer in suspend (or standby) mode. Press <Fn><Esc> (or <Scroll Lock><Esc> on an external keyboard if the

External Hot Key option is enabled in the system setup program).

●

(For Windows 95 only) Place the computer in S2D mode. Press <Fn><a> (or <Fn><q> on a French keyboard). When the green power

indicator turns off, go to step 3.

●

Remove the battery from the battery bay. Close the computer display and turn the computer over. Slide the battery bay latch to the

unlock position (see Figure 2), causing the battery to pop up slightly on one side. While keeping the latch in the unlock position, pivot the battery up and out of the bay. Release

the latch.

NOTES: A charge indicator that blinks rapidly indicates a temporary failure or a potentially recoverable failure such as overheating. Allow the battery to cool for several minutes before checking the charge level again.

If the battery has permanently failed or completely discharged, no charge indicators will light when you press the battery test button. If you install a failed or completely discharged battery in the computer and the battery status indicator turns red, the battery

has failed. If the battery status indicator turns red, allow the battery to charge overnight and check it the next day. If the battery is fully discharged, it takes a much longer time than usual to recharge it.

To purchase a new battery, call Dell or access the Dell World Wide Web site at http://www.dell.com. Dispose of the old battery properly.

Percentage of Charge

The battery charge gauge uses its four indicator lights to show the percent of charge remaining in the battery:

If one indicator lights up, the battery has 1 to 25 percent of its charge remaining.

●

If two indicators light up, the battery has 26 to 50 percent of its charge remaining.

●

If three indicators light up, the battery has 51 to 75 percent of its charge remaining.

●

If four indicators light up, the battery has 76 to 100 percent of its charge remaining.●

The second low-battery warning consists of a triple beep from the speaker, with the computer entering suspend (or standby) mode immediately after the beep if Battery Low Suspend is

enabled in the system setup program. If Battery Low Suspend is disabled, a low-battery icon appears on the display screen. This warning occurs when you have about 15 minutes of battery life left under current conditions and the computer is not connected to an electrical outlet.

After the second low-battery warning, if no further input/output (I/O) activity occurs within a few seconds, the computer enters S2D mode. If the computer has no S2D file, it enters suspend (or

standby) mode, in which it can preserve data for several hours. If the computer is already in suspend (or standby) mode when a final low-battery warning

occurs, the computer enters S2D mode immediately. If S2D mode has been disabled, the computer reenters suspend (or standby) mode.

NOTICE: To avoid losing data and possibly corrupting data areas on your hard-disk drive, save your work immediately after a second low-battery warning. Then connect your computer to an electrical outlet, or place the computer in suspend (or standby) mode. If the battery runs completely out of power, the computer turns off without properly closing any open files.

Detecting Battery Problems

A battery problem may prevent the battery from being charged to its full potential and can lead to unpredictable operation. To obtain a new battery, call Dell or access the Dell World Wide

Web site at http://www.dell.com. To avoid installing a defective battery in your computer, first check the battery's charge,

indicated by the battery charge indicators on the battery itself, by pressing the battery test button (see Figure 3).

NOTE: If the battery has 0 (zero) percent charge, you cannot use the battery test button to check the battery's capacity. The battery charge indicators will not light if the battery is completely drained.

Battery Disposal

CAUTION: Do not puncture or incinerate the battery.

NOTE: To purchase a new battery, call Dell or access the Dell World Wide Web site at http://www.dell.com.

Your computer system uses both a lithium-ion battery pack and a nickel-metal hydride (NiMH) coin cell battery. For instructions about replacing the lithium-ion battery pack in your computer, see "Replacing the Battery." The NiMH battery is a long-life battery, and it is very possible that

you will never need to replace it. However, if this battery ever needs to be replaced, the procedure must be performed by an authorized service technician.

Do not dispose of these batteries along with household waste. Contact your local waste disposal agency for the address of the nearest battery deposit site.

About Battery Power

You automatically conserve battery power each time you connect the computer to an electrical outlet. The battery is even being recharged when you use AC power. The battery's life expectancy is largely determined by the number of charges it receives, so use an electrical outlet to run the computer whenever possible.

You can customize power management by individually controlling the computer's power

conservation features. These features reduce power consumption by monitoring application

programs and computer devices for inactivity and slowing down or stopping some of the computer’s internal devices.

NOTES: When you use power conservation features, you often trade some of the performance of the computer for increased battery operating time. For example, if you turn off the hard-disk drive, you may experience a delay the next time the computer tries to access the hard-disk drive.

Other power conservation features, such as suspend (or standby) mode, stop almost all system activity. They allow you to maximize power conservation when your work is

interrupted.

Experiment with power conservation features to achieve the optimum power conservation for your work environment.

PC Cards: Dell™ Latitude™ LS Portable Computers User's Guide

About PC Cards Removing PC Cards

Installing PC Cards Configuring PC Cards

About PC Cards

On the right side of the computer is a PC Card slot in which you can install PC Cards that comply with Release 2.01 of the Personal Computer Memory Card International Association (PCMCIA) standard and Release 4.2 of the Japanese Electronic Industry Development Association (JEIDA) standard.

The computer supports type I and type II PC Cards, such as modems, local area network (LAN) cards, wireless LAN cards, and small computer system interface (SCSI) cards. Also supported are such memory devices as static random-access memory (SRAM) cards that emulate diskettes, random-access memory (RAM) cards, and one-time programmable (OTP) ROM cards, and advanced technology attachment (ATA) cards that emulate integrated drive electronics (IDE) hard-disk drives.

If you are using the Microsoft® Windows® 95 or Windows 98 operating system, you can use a zoomed video (ZV) PC Card, such as a hardware Moving Picture Experts Group (MPEG) decoder. (The Microsoft Windows NT® 4.0 operating system does not support ZV.)

NOTES: A PC Card is not a boot device. The "type" of a card refers to its thickness, not its functionality. Your computer recognizes most input/output (I/O) cards and automatically loads the

device driver associated with that card.

NOTICE: Take extra precautions if you use extended PC Cards in your computer. Extended cards are longer versions of standard PC Cards. They fit into, and operate correctly with, your computer. However, they extend beyond the edge of the computer when installed. If something strikes the exposed end of an installed card, your system board can be damaged. Always remove an extended PC Card before you pack the computer in its carrying case.

Page 64

Installing PC Cards

PC Cards are generally marked with a symbol, such as a triangle or an arrow, to indicate which end should be inserted into the slot. The cards are keyed to prevent incorrect insertion. If card orientation is not clear, see the documentation that came with the card.

You do not need to turn off your computer or exit suspend or standby mode before you install a PC Card. To install a PC Card (see Figure 1), perform the following steps.

Figure 1. Installing a PC Card

If necessary, remove the blank from the PC Card slot. Press the eject button once to pop the button out, press it again to eject the blank partway, and then pull the blank out.

Make sure that the eject button is pressed all the way in. Hold the card with its orientation symbol pointing into the slot and the top side of the card facing up.

Insert the card into the slot and press in firmly until the card is completely seated in the internal PC Card connector.

If you encounter too much resistance when inserting it, do not force the card. Check the card's orientation and try again.

PC Card Blanks

Save the blank to use whenever you do not have a PC Card installed. The blank protects the PC Card slot from dust and other particles.

Securing Your Computer: Dell™ Latitude™ LS Portable Computers User's Guide

About Passwords Using a Hard-Disk Drive Password

Using a Supervisor Password Physically Securing the Computer and

the Hard-Disk Drive

Using a User Password

About Passwords

A user password prevents unauthorized access to the computer at start-up. A supervisor password provides access to the system setup program. A hard-disk drive password helps prevent the unauthorized access of data on the hard-disk drive, even when the device is placed into another computer.

NOTES: All three passwords are disabled when you receive your computer. You need to assign those passwords if you require password security for your computer. Some companies may assign any or all of these passwords before distributing the computer.

Use the system setup program to assign all passwords.

NOTICE: The password features provide a high level of security for the data in your computer or hard-disk drive. However, they are not foolproof. If your data requires more security, you should obtain and use additional forms of protection, such as data encryption programs or PC Cards with encryption features.

If you forget any of your passwords, call Dell. For your protection, Dell’s technical support staff will ask you for proof of your identity to make sure that an unauthorized person is not trying to

use the computer.

Using a Supervisor Password

The supervisor password is designed to give system administrators or service technicians in large companies access to computers for repair or reconfiguration. The administrators or technicians can assign identical supervisor passwords to groups of computers as they are unpacked and configured, leaving the user password free to be assigned by the user.

Securing Your Computer: Dell Latitude LS Portable Computers User's Guide

file:///C|/Documents and Settings/Administrator/De... Web/Documentation/LS/LS User's Guide/security.htm (1 of 4) [5/31/2000 9:46:33 AM]

Page 71

The supervisor password overrides the user password. Whenever you are prompted to enter the user password, you can enter the supervisor password instead.

NOTE: The supervisor password provides access to the computer, but it does not provide access to the hard-disk drive when the drive is protected by a password.

If you forget the user password and do not have a supervisor password assigned, or if you have both a user and a supervisor password assigned but forget them both, call Dell.

NOTICE: Disabling the supervisor password disables the user password.

Using a User Password

The user password allows you to protect the computer from unauthorized access.

NOTE: Before assigning a user password, you must set a supervisor password.

After assigning a user password, you must enter it each time you turn on your computer. The following message appears at the bottom of the screen each time you turn on the computer:

Enter Password

To continue, type your password and press <Enter>. If you assigned a supervisor password, you can use it instead of the user password. The

computer does not specifically prompt you for the supervisor password.

NOTICE: Disabling the supervisor password disables the user password.

Using a Hard-Disk Drive Password

The hard-disk drive password helps protect the data on your hard-disk drive from unauthorized access.

NOTE: Hard-disk drives that are not purchased from Dell for use with your computer may not support the hard-disk drive password option.

After assigning a hard-disk drive password, you must enter it each time you turn on the computer and each time you resume normal operation from suspend mode or standby mode.

If the hard-disk drive password is enabled, the following message appears each time you turn on the computer:

Enter HD1 Password

To continue, enter the hard-disk drive password. Press <Esc> to return the computer to its previous state—suspend, standby, or off.

in the system setup program are set to allow booting from another device, the computer tries to boot from another device. If all boot attempts are unsuccessful, the computer prompts you to enter the system setup program and modify the boot options.

NOTES: If the hard-disk drive password is different from the user password, you are prompted for both. Two different passwords provide greater security.

The supervisor password provides access to the computer, but it does not provide access to the hard-disk drive when the drive is protected by a password.

Physically Securing the Computer and the Hard-Disk Drive

To prevent unauthorized removal of the computer, you can use a security cable to attach the computer to an immovable object. Your computer has a security cable slot located on the right side of the computer next to the hard-disk drive (see Figure 1).

Description of Security Cable Slots

The security cable slot allows you to attach a commercially available antitheft device to the computer. Antitheft devices for portable computers usually include a segment of metal-stranded cable with an attached locking device and associated key. You can use a security cable on your computer whether it is undocked or docked in a Dell Latitude LS Advanced Port Replicator (APR).

Basic Instructions for Using Security Cable Slots

To prevent unauthorized removal of your computer, loop the cable around an immovable object, insert the locking device into the security cable slot, and lock the device. See Figure 1 for an example of how to secure your computer. Complete instructions for installing this kind of antitheft device are usually included with the device.

About the I/O Connectors

You can connect external devices to the input/output (I/O) connectors on the back and left side of the computer (see

Figure 1). The computer's basic input/output system (BIOS) detects the presence of the external devices when you boot

(start) or reboot your computer. You can connect to the Dell Latitude LS Advanced Port Replicator (APR) through the

docking connector on the bottom of the computer.

NOTES: Some external devices require you to load software called device drivers into system memory before using the devices. These device drivers help your computer recognize the external device and direct its operation. Instructions for installing this software are usually included in the upgrade kits.

The APR provides the same I/O connectors as your computer and, in addition, provides a serial port. For more information on the APR, see the documentation that came with it.

Mouse, Keyboard, and External Numeric Keypad

You can attach a Personal System (PS)/2-compatible device such as a mouse, 101- or 102-key keyboard, or external numeric keypad to the mini-DIN PS/2 connector.

Mouse

NOTE: If the computer is in suspend (or standby) or suspend-to-disk (S2D) mode when you attach a mouse, you can use the mouse when the computer resumes normal operation. However, programs that were already running

may need to be restarted to recognize the mouse. If the computer is not in suspend (or standby) or S2D mode when you attach the mouse, you must reboot the computer to use the mouse.

When you attach a PS/2 mouse to the computer, the touch pad is automatically disabled. If you disconnect the mouse, you must shut down the computer or enter suspend or standby mode and then resume from it before the touch pad is operational. If you do not do this, the touch pad resumes operation in standard PS/2 mode, which means that many of the configuration features are disabled.

If you are using a PS/2-compatible mouse that is not made by Microsoft and the mouse does not work properly, reboot the computer. If the mouse still does not work, install the drivers from the diskette that came with the mouse and reboot the computer.

Keyboard

NOTE: If the computer is in suspend (or standby) mode or S2D mode when you attach an external keyboard, the device is recognized immediately by the computer when it resumes normal operation.

You can use the computer's keyboard and an external keyboard at the same time. When you attach a keyboard to the

computer, the embedded numeric keypad is automatically disabled. On an external keyboard, the <Scroll Lock> key acts the same way as the <Fn> key on the computer’s keyboard (if the

External Hot-Key option is enabled in the system setup program).

External Numeric Keypad

NOTE: If the computer is in suspend (or standby) mode or S2D mode when you attach an external numeric keypad, the device is recognized immediately by the computer when it resumes normal operation.

When you attach an external numeric keypad to the computer, the numeric keypad on the computer keyboard is automatically disabled. The indicators on the integrated keyboard track the operation of an external numeric keypad.

USB Devices

You can attach a USB hub device to the USB connector. The USB hub device can support multiple USB devices (typically low-speed peripherals such as mice, keyboards, printers, and computer speakers).

Parallel Devices

You can attach a parallel device (usually a printer) to the 25-pin parallel connector. You can also connect the diskette drive to the parallel connector.

The parallel port sends and receives data in parallel format, where eight data bits (one byte) are sent simultaneously over eight separate lines. The port can be configured as a unidirectional (output-only) port for devices such as a printer or as a bidirectional port for devices such as a network adapter.

The computer's integrated parallel port is designated as LPT1. The Microsoft® Windows® 95 and Windows 98 operating systems automatically recognize the parallel device and configure it correctly. The parallel port can also be configured for compatibility with the PS/2 standard.

Connecting a Diskette Drive to the Parallel Connector

You can use the diskette drive as a second external device if you already have a device connected to the media bay connector. The diskette drive letter is A, unless a diskette drive is already installed in the external media bay, in which case the drive connected to the parallel connector is drive B.

To connect the drive to the parallel connector on the I/O panel, use the optional parallel diskette-drive cable (available from Dell), as shown in Figure 2.

Experimenting With Power Conservation

In general, the lower the value you set for each power conservation feature, the longer the

battery's charge lasts. On the other hand, setting high values tends to optimize the computer's

performance. To evaluate the way that different settings affect how long you can operate the computer on

battery power versus the relative efficiency of how the software performs, experiment as follows:

Use the computer with all the options set at their default values.

●

Use the computer with all the options disabled or set to Off.●

Use the computer with all the options set to their minimum or maximum values.●

Using Key Combinations

Table 1 identifies the power management key combinations.

NOTE: To use key combinations on an external keyboard, enable the External

Hot-Key option in the system setup program, and press <Scroll Lock> instead of <Fn>.

* This key combination does not function under an operating system with the Advanced Configuration and Power Interface (ACPI), such as Microsoft® Windows® 98.

Closing the Display

One way to conserve power on the computer is to close the display when the computer is not in use. When you close the display and an external monitor is not connected, the computer's display shuts off and the computer enters suspend mode (standby mode in Windows 98).

NOTE: If an external monitor is connected when you close the display, the computer does not activate suspend (or standby) mode. You can still use the external monitor.

To resume work, open the display. (The computer may take several seconds to resume operation.)

Suspend Mode

If your computer is running the Microsoft Windows 95 or Microsoft Windows NT® operating system, suspend mode stops almost all computer activity, but leaves the computer ready to resume operations immediately in about 20 to 30 seconds. Use suspend mode whenever you leave the computer unattended.

Power Management Settings: Dell Latitude LS Portable Computers User's Guide

file:///C|/Documents and Settings/Administrator/De... Web/Documentation/LS/LS User's Guide/batpower.htm (2 of 5) [5/31/2000 9:46:52 AM]

Page 82

NOTICE: Windows 95 and Windows NT save data to random-access memory (RAM), not to your hard-disk drive, before entering suspend mode. If the computer enters suspend mode while running on battery power, data loss from RAM can occur if the battery discharges completely.

Suspend mode conserves battery power by turning off the microprocessor clock; the display; the hard-disk drive; the CD-ROM, DVD-ROM, or LS-120 drive module (if installed); the external monitor connector; the external keyboard (if attached); the parallel port; the serial port; the touch pad; and the diskette drive.

You can enter suspend mode immediately by pressing <Fn><Esc> (or <Scroll Lock><Esc> on an external keyboard if the External Hot-Key option is enabled in the system setup program).

When you enter suspend mode, the power indicator is not lit. Resume from suspend mode by pressing the power button. The computer may take several

seconds to return to normal operation.

NOTES: On resumption from suspend mode, if a password is set, the computer displays the password prompt screen.

Suspend mode is known as standby mode under the Microsoft Windows 98 operating system.

Standby Mode

If your computer is running the Microsoft Windows 98 operating system, standby mode turns off the display, stops the hard-disk drive, and turns off other internal devices so that the computer uses less battery power. When the computer resumes operation from standby mode, the desktop is restored exactly as it was before entering standby mode.

NOTICE: Windows 98 saves data to random-access memory (RAM), not to your hard-disk drive, before entering standby mode. If the computer enters standby mode while running on battery power, data loss from RAM can occur if the battery discharges completely.

You can enter standby mode by pressing <Fn><Esc>.To resume operation from standby mode, press the power button.

Suspend-to-Disk (Hibernate) Mode

Suspend-to-disk (S2D) mode (known as hibernate under the Microsoft Windows 98 operating system) copies all system data to a reserved area—the S2D file—on the hard-disk drive and then turns off all power to the computer. When you resume normal operation, the same programs will be running and the same files will be open that were loaded before you activated this mode.

Power Management Settings: Dell Latitude LS Portable Computers User's Guide

file:///C|/Documents and Settings/Administrator/De... Web/Documentation/LS/LS User's Guide/batpower.htm (3 of 5) [5/31/2000 9:46:52 AM]

Page 83

Place the computer in S2D mode if you intend to store the computer for a month or more. S2D mode preserves the configuration information stored in nonvolatile random-access memory (NVRAM). The reserve battery maintains this information, but it may run out of energy after about a month.

NOTE: S2D mode helps preserve system data by quickly saving it to the hard-disk drive if you are about to run out of battery power.

If the External Hot-Key option is enabled in the system setup program, you can enter S2D mode by pressing <Fn><a> (or <Scroll Lock><a> on an external keyboard). On a French

keyboard, press <Fn><q> or <Scroll Lock><q>.

NOTE: These key combinations do not function under an operating system with ACPI, such as Windows 98.

Resume operation from S2D mode by pressing the power button. Some PC Cards may not operate correctly after resuming from S2D mode. If you encounter

problems with a card, remove and reinsert the card.

NOTE: Dell creates an appropriately sized S2D file before shipping the computer to you. Use the Suspend-to-Disk Utility to remove the file, to increase the size of the file, or to add the S2D file if you removed it. For information on creating a S2D file, see "Suspend-to-Disk Utility."

Power Management Properties for Windows 98

Windows 98 with ACPI provides the Power Management Properties window for setting power conservation features.

NOTE: Set timeouts and enable hibernate (S2D) mode through the Power Management Properties window rather than through the Power screen in the system

setup program.

To access the Power Management Properties window and set the power management features, perform the following steps:

Click the Start button, point to Settings, and click Control Panel.1.

Double-click the Power Management Properties icon. The Power Management Properties window contains the following tabs:

Power Scheme — allows you to change individual power management settings or select one of three power mode settings (Always On, Home/Office Desk, or Portable/Laptop) that each provide a set of default

power management settings.

Alarms — allows you to set the Low Battery and Critical Battery alarms to alert you when the battery charge falls below a certain percentage. When you

received your computer, the Low Battery and Critical Battery alarm options were not checked. Dell recommends that you do not select these options.

●

Power Meter — allows you to view the percentage of battery life remaining when your computer is operating on battery power. If your computer is operating on AC power, the computer displays a message.

●

Advanced — allows you to display the Power Meter on the Windows 98 taskbar and to display a password prompt when the computer resumes operation from standby mode. Advanced also allows you to define the action

of the Power buttons.

●

Hibernate — allows you to enable hibernate (S2D) mode in Windows 98.●
