not ringing in response to an incoming call. In most, but not all, areas the sum of
the RENs should not exceed five (5.0). To be certain of the number of devices that
may be connected to the line, as determined by the total RENs, contact the
telephone company to determine the maximum REN for the calling areas.

If the terminal equipment causes harm to the telephone network, the telephone
company will notify you in advance that temporary discontinuance of service may
be required. But if advance notice isn't practical, the telephone company will notify
the customer as soon as possible. Also, you will be advised of your right to file a
complaint with the FCC if you believe it necessary.

The telephone company may make changes in its facilities, equipment, operations,
or procedures that could affect the operation of the equipment. If this happens, the
telephone company will provide advance notice in order for you to make the
necessary modifications in order to maintain uninterrupted service.

If trouble is experienced with this equipment, please contact Dell Computer
Corporation for repair and warranty information. If the trouble is causing harm to
the telephone network, the telephone company may request you remove the
equipment from the network until the problem is resolved.

Blinking (green) Suspended to RAM

The warning beep sounds.

Basic Operations

2-2

Using the AC Adapter

When connected to a wall outlet, the AC adapter provides power for operation and

charges the battery. The AC input voltage can range from 100 to 240 volts so that
you can use the computer with the appropriate plug adapter.

Resetting the System

You may need to reset the system after adding hardware or software so that your

computer will recognize the newly installed devices or software. When the message
appears after the installation, click OK, Yes, etc. to restart the operating system.
You can also restart the operating system from the Start menu. Select Shut down
then Restart.

Warm Boot

If the system is locked up because of a software problem, you can reset or reboot the

system by pressing the Ctrl+Alt+Del keys simultaneously. Press the Ctrl+Alt+Del
keys again to restart the computer.

Power Switch

The AC power cord included with the computer is appropriate for the

voltage used in the area in which you purchased your computer. If you
attempt to connect the computer to a wall outlet other than in this area,
check the voltage of the outlet and use an AC power cord appropriate for
the outlet. Consult local service staff if you are unsure.

Resetting may cause data loss. Use the software reset only if the normal
Shut Down does not work because of software malfunction. Although
resetting will not damage the system, you may lose the data you are
processing.

Dell Latitude LT System User’s Guide

2-3

You can turn off the computer with the power switch if you encounter hardware or
software problems which lock up the system. In this case, slide and hold the switch
for more than 5 seconds.

Reset Switch

If you cannot turn off the computer by sliding the power switch, you can use the
reset switch on the bottom of your computer. To reset the system, insert a narrow
object into the small hole to slide the switch as shown.

Do not use metallic materials to slide the reset switch. Doing so may
cause malfunction.

Using the Glide Pad

Your computer is equipped with an integrated pointing device called a glide pad.

Using the glide pad, you can move the pointer, select an item from a menu, and
perform other tasks in the same way you would with a mouse.

• Do not hit or scratch the surface of the glide pad with pointed objects

(such as a ballpoint pen).

• Do not operate the glide pad with a moist finger. This may cause the

glide pad to operate incorrectly.

• You cannot use the glide pad when a mouse is connected.

Basic Operations

2-4

Using the Glide Pad

Take a moment to become familiar with how the glide pad works.

Place Your Fingertip

Place your left or right hand next to the glide pad, resting your wrist naturally in a
relaxed manner. Place your thumb or finger on the glide pad.

Move Your Fingertip

The rectangular pad of the glide pad acts like a miniature duplicate of the display.
As you slide your fingertip across the pad, the pointer on the screen moves in the
same direction across the screen. The glide pad is very sensitive, so you do not have
to exert a lot of pressure on the pad. The glide pad will respond to a light touch
from your fingertip.

Click, Double-click, and Right-click

To click or double-click, you can use the left button just like that of a mouse.
Instead of clicking by pressing the left button, you can just tap gently anywhere on
the rectangular pad. For right-clicking, you can use the right button.

Drag and Drop

You can move icons or windows by using “drag and drop” as follows:

1. Position the pointer over the object.

2. Press the left button; do not release it.

3. Holding down the button, move the pointer. The object moves together with

the pointer.

4. Release the button when the object reaches its destination.

Dell Latitude LT System User’s Guide

2-5

Scroll

You can scroll through information in a list or in a document by using the glide
pad. Place your finger on the right part of the glide pad and move it back and forth.
This procedure works only in some applications.

Changing the Configuration

In the Mouse Properties dialog box, you can change the configuration of the glide
pad, such as swapping left and right buttons, changing the pointer size, etc.

• If you swap the left and right buttons, "tapping" on the glide pad as an

alternative method of pressing the left button will no longer function.

• If you prefer to use a mouse and turn off the glide pad, you can disable

the glide pad in the Setup Utility. See also Chapter 4.

Using the Keyboard

Your computer, equipped with the Windows Enhanced Keyboard, provides all the

functionality of a full-sized desktop keyboard.

Windows Logo Keys

Opens the Windows Start menu.

System Function Keys
When pressed together with the Fn key, function keys set specific system

parameters. This combination is sometimes referred to as “hot keys.”

CHAPTER 3

Battery and Power Management

This chapter explains how to manage the computer’s power effectively and use the
standard battery or an optional battery pack.

Standard Battery Pack

When not connected to an external power source, your computer operates with the
rechargeable internal standard battery pack. The duration of the battery life may be
longer if the computer’s power management is active. See the Power Management
section in this chapter for information about power management.

To keep the battery life long:

• Use the procedure in the Initialize the Battery Pack section in this chapter if the

actual remaining power in your battery is less than what the battery indicator
lights suggest.

• Turn off your computer when you are not using it.

• The duration a battery charge will last will depend on the computer

usage. Heavy use the peripherals, like the external floppy disk drive
unit or the optional external CD-ROM drive, will result in shorter
power duration.

• When the battery is not charged, your computer may not operate

properly. Connect the AC power to charge the battery.

• If you see an error message during booting, press F2 to open the

Setup Utility. Following the instructions in Chapter 7, adjust the
Setup Utility and restart the system.

• When using the computer for several hours with battery packs, enable

power management and set the suspend-to-disk mode. Refer to the
Power Management section in this chapter and the Power Menu
section in Chapter 7.

Battery and Power Management

3-2

Checking the Battery Level

You can check the battery level in the Power Management properties dialog box in
the Control Panel or by double-clicking the battery or AC plug icon on the taskbar.

You can also check the battery indicator on the front side of the computer.

Press the button on the right of the battery indicator to show the battery power
remaining. Refer to the table below.

This battery indicator turns on automatically while the battery is being charged
(when connected to AC power). When the battery is fully charged, the battery
indicator turns off.

The battery power remaining is an approximate figure. The remaining
operating time expected may be different from the actual remaining
time, depending on the use of the computer. If the actual remaining
power in your battery is less than what the battery indicator lights
suggest, you should initialize the battery pack. See Initializing the
Battery Pack later in this chapter.

Dell Latitude LT System User’s Guide

3-3

Low Battery Indication

When the battery power becomes significantly low, the battery power indicator ( )
turns red and the warning beep sounds. Save your data and turn off the computer,
or connect the computer to a wall outlet immediately. The computer will suspend
data to disk when there is significantly low battery power. You can adjust this
activity in the Power menu of the Setup Utility. When your computer suspends, do
not turn on the computer before connecting it to a wall outlet or connecting a fully
charged optional external battery pack.

In the Windows operating system, you can set the alarm to inform you of the
remaining battery level. In the Power Management properties dialog box, select the
Alarms tab and set Low battery alarm and Critical battery alarm.

The remaining operating time depends on the power you are consuming. If you are
using the audio system, PC card slot, hard disk drive or external floppy disk drive
unit, your computer may consume more battery life.

See also the section on power management in this chapter.

Charging the Battery Pack

1. Connect the AC adapter to the computer. While the battery is being charged,

the battery power indicator is orange and the battery indicator turns on.

2. When the battery is fully charged, the battery power indicator turns green and

the battery indicator turns off. Charging time may vary according to the
status of the computer.

When the battery is hot (for example, after long use), it may take longer
to fully charge the battery.

Initializing the Battery Pack

You need to initialize the battery pack when the actual remaining power in your
battery is less than what the battery indicator lights suggest.

1. Connect the computer to AC power and wait until the battery is fully charged.

The battery power indicator turns green and the battery indicator turns off. It
will take about 2 hours and 30 minutes if the battery is completed discharged.

• Do not connect the computer to a wall outlet while discharging the

battery. The initialization will be cancelled.

• You can initialize the standard battery alone only if the optional

external battery pack is disconnected. When the external battery pack
is connected, both the standard and the external battery will be
initialized together.

Changing the Battery Pack

The capacity of a battery pack gradually decreases when used repeatedly (the
deterioration rate depends on the operating temperature and environment). If the
battery life becomes extremely short even after the initialization, you should change
the standard battery pack. Contact your local Dell Service Representative to replace
the standard battery pack.

Never replace the standard battery pack by yourself.

Dell Latitude LT System User’s Guide

You can charge the external battery pack by connecting AC power to the computer
with the external battery connected. To charge most effectively, the standard and
external battery pack should be charged as follows:

1. Charge standard battery pack to 80%.

2. Charge external battery pack to 80%.

3. Charge standard battery pack remaining 20%.

4. Charge external battery pack remaining 20%.

When the computer is turned off or in the suspend-to-disk mode, it will take about
5 hours and 30 minutes to charge both the standard and external battery packs from
empty to full. When the computer is turned on, it will take about 7 hours and
30 minutes. (The charging time depends on the power you are consuming.)

Initializing External Battery Pack

The procedure for initializing an external battery pack is the same as that of the
standard battery. But, you cannot initialize the external battery pack only. If you
begin the initializing process, both standard and external battery packs will be
initialized.

Disposing of the Battery

This computer contains or is supplied with a lithium-ion battery.
Lithium-ion batteries are longer life batteries than other
conventional battery chemistries and do not require replacement
as often. The internal battery must be replaced by a Dell service
representative, and the external battery may be replaced with a
Dell-provided replacement. Spent batteries should not be placed
in common household waste. Contact local authorities for the
location of a chemical waste collection program nearest you.

Suspend Modes

The power management feature contains two types of suspend modes: suspend-to-

RAM mode and suspend-to-disk mode. In the Setup Utility, you can define which
suspend mode the system enters in what conditions.

• Suspend-to-RAM mode stores the current condition of the computer in RAM

and stops power supply to all but a few essential components. Your system enters
and resumes from the suspend-to-RAM mode per the conditions mentioned
below. In the suspend-to-RAM mode, the Power indicator blinks green.

• Suspend-to-disk mode saves the current condition of the computer in an area of

the hard disk, which is called “suspend-to-disk partition,” and turns off the
computer. Your system enters and resumes from the suspend-to-disk mode per
the conditions mentioned below. In the suspend-to-disk mode, the Power
indicator turns off.

Before Suspending the System
Finish communications, printing and playing music or video before suspending the

system.

Entering the Suspend Modes
Your computer enters a suspend mode in each of the following cases. Set Suspend

Mode in the Power menu of the Setup Utility to trigger the suspend mode under the
following circumstances:

Suspend/Resume in the Setup Utility.

Resuming From Suspend-to-Disk Mode
Your computer resumes from the suspend-to-disk mode when you slide the power

switch. The system restores the exact state as it was when entering the suspend
mode. If the computer enters the suspend mode because of low battery power,
however, you have to connect the computer to AC power first. Suspend-to-disk
mode is useful when you want to turn off the computer and reopen the same
windows after turning it on.

• If your battery becomes completely discharged while in suspend-to-

RAM mode, you will lose unsaved data and will need to reboot your
computer. Therefore, if you are planning to leave your computer
suspended for long periods of time, Dell recommends using suspend­to-disk mode.

• When the system enters or resumes from the suspend-to-disk mode,

you can see some flicker on the display. This is not a malfunction.

• If sufficient battery power does not remain, your computer will not

resume from the suspend-to-disk mode. To resume it from the suspend­to-disk mode, connect the computer to AC power.

• If a PC card does not work properly after your computer resumes from

the suspend-to-disk mode, restart the computer.

When entering or resuming from a suspend mode, be sure to observe the
following precautions. Otherwise, the computer may not operate
correctly after it has resumed from the suspend mode.

• Do not turn off the computer when the system is suspended to RAM.

The RAM contents will be lost.

• Do not operate the keyboard, glide pad or mouse while the system is

entering or resuming from a suspend mode.

CHAPTER 8

Getting Help

This chapter describes the tools Dell provides to help you when you have a problem
with your computer. It also tells you when and how to call Dell for technical or cus­tomer assistance.

Help Tools

Dell provides a number of tools to assist you. These tools are described in the
following sections.

Some of the following tools are not always available in all locations
outside the continental U.S. Please call your local Dell representative

AutoTech Service

Dell’s automated technical support service—AutoTech—provides recorded answers
to the questions most frequently asked by Dell customers.

When you call AutoTech, you use your touch-tone telephone to select the subjects
that correspond to your questions. You can even interrupt an AutoTech session and

Dell Latitude LT System User’s Guide

continue the session later. The code number that the AutoTech service gives you
allows you to continue your session where you ended it.

The AutoTech service is available 24 hours a day, seven days a week. You can also
access this service through the technical support service. For the telephone number
to call, refer to Dell Contact Numbers found later in this chapter.

TechFax Service

Dell takes full advantage of fax technology to serve you better. Twenty-four hours a
day, seven days a week, you can call the Dell TechFax line toll-free for all kinds of
technical information.

Using a touch-tone phone, you can select from a full directory of topics. The
technical information you request is sent within minutes to the fax number you
designate. For the TechFax telephone number to call, refer to Dell Contact
Numbers found later in this chapter.

Technical Support Service

Dell’s industry-leading hardware technical-support service is available 24 hours a
day, seven days a week, to answer your questions about Dell hardware.

Our technical support staff pride themselves on their track record: more than 90
percent of all problems and questions are taken care of in just one toll-free call,
usually in less than 10 minutes. When you call, our experts can refer to records
kept on your Dell system to better understand your particular question. Our
technical support staff use computer-based diagnostics to provide fast, accurate
answers to questions.

To contact Dell’s technical support service, first refer to the section titled Before

You Call and then call the number for your country as listed in Dell Contact
Numbers found later in this chapter.

Problems With Your Order

If you have a problem with your order, such as missing parts, wrong parts or
incorrect billing, contact Dell Computer Corporation for customer assistance. Have
your invoice or packing slip handy when you call. For the telephone number to call,
refer to Dell Contact Numbers found later in this chapter.

Product Information

If you need information about additional products available from Dell Computer
Corporation, or if you would like to place an order, visit Dell’s World Wide Web
site at www.dell.com/. For the telephone number to call to speak to a sales
specialist, refer to Dell Contact Numbers found later in this chapter.

Returning Items for Warranty Repair or Credit

Prepare all items being returned, whether for repair or credit, as follows:

1. Call Dell to obtain an authorization number, and write it clearly and

prominently on the outside of the box. For the telephone number to call, refer
to Dell Contact Numbers found later in this chapter.

2. Include a copy of the invoice and a letter describing the reason for the return.

Dell Latitude LT System User’s Guide

8-5

3. Include any accessories that belong with the item(s) being returned (power

cables, software diskettes, guides and so on) if the return is for credit.

4. Pack the equipment to be returned in the original (or equivalent) packing

materials.
You are responsible for paying shipping expenses. You are also responsible for
insuring any product returned, and you assume the risk of loss during shipment
to Dell Computer Corporation. Collect-on-delivery (C.O.D.) packages are not
accepted.

Returns that are missing any of the preceding requirements will be refused at our
receiving dock and returned to you.

Before You Call

Have your Express Service Code ready when you call. The code helps
Dell’s automated-support telephone system direct your call more
efficiently.

If possible, turn on your system before you call Dell for technical assistance and call
from a telephone at or near the computer. You may be asked to type some
commands at the keyboard, relay detailed information during operations or try
other troubleshooting steps possible only at the computer system itself. Make sure
the system documentation is available.

Contacting Dell

When you need to contact Dell, use the telephone numbers and codes provided in
the next sections. International Dialing Codes provides the various codes required
to make long-distance and international calls. Dell Contact Numbers provides local
telephone numbers, area codes and toll-free numbers, if applicable, for each
department or service available in various countries around the world. If you are
making a direct-dialed call to a location outside of your local telephone service
area, determine which codes to use (if any) in International Dialing Codes in
addition to the local numbers provided in Dell Contact Numbers. For example, to
place an international call from Paris, France to Bracknell, England, dial the
international access code for France followed by the country code for the U.K., the
city code for Bracknell and then the local number.

Getting Help

8-6

To place a long-distance call within your own country, use area codes instead of
international access codes, country codes and city codes. For example, to call Paris,
France from Montpellier, France, dial the area code plus the local number.

The codes required depend on where you are calling from as well as the destination
of your call; in addition, each country has a different dialing protocol. If you need
assistance in determining which codes to use, contact a local or an international
operator.

Toll-free numbers are for use only within the country for which they are
listed. Area codes are most often used to call long distance within your
own country (not internationally)—in other words, when your call
originates in the same country you are calling.

Troubleshooting

This chapter describes how to troubleshoot computer problems.

Common Problems

Problems with your computer can be caused by something as minor as an
unplugged power cord or as major as a damaged hard disk drive. The information
in this troubleshooting section is designed to help you find and solve minor
problems. If you still have a problem after trying all the suggested remedies in this
chapter, contact your service representative.

The problems that you might encounter can be divided into two basic categories:
hardware and software. Hardware problems can be further divided into being of an
electrical or a mechanical nature. You will know you have a hardware problem if,
for example, the screen is blank, or the computer cannot recognize the disk drives.

Software problems can occur at several levels. Both your operating system and your
software application programs are capable of generating errors and error messages.
If you encounter a software error, try to determine if the error message is from your
operating system or from an application program, and refer to the appropriate
manual for possible remedies.

You can also refer to the operating system manual or Windows Help program to
solve the problem. To access the Help program, select Help from the Start menu. It
also gives you Troubleshooting tips and an Index.

Successful troubleshooting is the result of careful observation, deductive reasoning,
and an organized approach to solving the problem. If you encounter a problem,
begin by performing a careful visual inspection. Check the exterior of the computer
first. If no lights are displayed, check the battery charge or power outlet, the plug
and power cord, and any power switches that may affect your computer. If the

computer has been connected to any peripheral devices, look for loose or
disconnected cables. You may also need to check the fuses and breakers in your
electric box. A few common problems and suggested solutions are presented in the
examples which follow.

Trouble When Starting

Question: Why doesn't the power switch function?

• Make sure the AC power cable is correctly connected to a live wall outlet.

• If the computer is operating with batteries, batteries may be discharged. Connect

the computer to a wall outlet.

Question: Why doesn't Windows start?

• Check whether the external floppy disk drive unit contains a non-system disk.

Remove the floppy disk from the drive, and press any key.

• If you are attempting to boot from the external floppy disk drive, check to make

sure the disk is fully inserted and seated into the drive.

• If you attempt to boot from the external floppy disk drive, check whether the

Diskette Drive is the first device in Boot Sequence in the Main menu of the
Setup Utility.

Question: Why do I get a non-system disk or disk error message?

• You may have inserted a non-bootable disk in the external floppy disk drive unit

(either a defective disk or one without an installed operating system). Remove
the disk.

• If this message is issued when you attempt to boot from your hard disk drive,

insert a bootable disk into the external floppy disk drive unit and check the status
of your hard disk drive.

• Check whether the items Diskette A: and Hard Disk Type: are correctly set in

the Main menu of the Setup Utility.
