Learning About Batteries

The computer accommodates up to two rechargeable battery packs
at one time. Battery packs are supported in the:

Battery bay in the computer (primary battery pack)

■

MultiBay in the computer (secondary battery pack)

■

With the computer turned off, each battery pack will recharge in
less than two hours. With the computer turned on, each battery
pack will recharge in less than five hours.

If two fully charged battery packs are installed, you can remove
one battery while the computer is on without affecting system
operation. With only one battery pack installed, you must turn off
the computer or initiate Hibernation before removing a battery, or
you must connect to external AC power before you remove the
battery pack. For more information on using Hibernation, see
Chapter 5.

When the computer is in Suspend, you must always have a power
source, either a fully charged battery pack or AC power, before
removing a battery pack. For more information on using Suspend,
see Chapter 5.

Ensuring Battery Gauge Accuracy

The built-in battery gauge, which displays the amount of charge
remaining, is precalibrated for accuracy. To ensure continued
battery gauge accuracy and to maximize battery operating time:

Fully charge the battery pack before the first time you use it.

■

Allow the battery pack to completely charge before removing

■

external power from the computer, convenience base, or
battery charger.

If the battery has been out of the computer for two weeks or

■

more, fully recharge the battery pack before using it.
Approximately every 60 days, allow the battery to completely

■

discharge to the low battery condition through normal use
before recharging it.

NOTE:

The various battery gauges available on your system should
be regarded as an approximate indication of remaining battery life.
Use the battery until the first warning is received, even if the
gauge indicates "no power."

Identifying a Low Battery Condition

When a low battery condition is reached, the computer beeps
twice approximately every five minutes, and the battery power
light blinks once per second. When a critical low battery
condition is reached, the computer beeps four times every five
seconds, and the battery light blinks twice per second.

CAUTION:

little battery charge remains. Take immediate action to resolve the
condition.

When a low battery condition is reached, save your files and
initiate Suspend. You have approximately 5 to 10 minutes to

Storing Battery Packs

When storing the computer for more than two weeks, remove the
battery packs and store them separately to reduce the discharge
rate and increase battery life.

Battery packs self-discharge even when they are not being used.
The rate of self-discharge is affected by temperature. To prolong
battery charge, store batteries in a cool, dry place. High
temperatures cause battery packs to lose their charge more
quickly, thus reducing battery life.

Using Battery Packs 4-7

The recommended storage temperature range is from 32°F to
104°F (0°C to 40°C). However, batteries can be stored at 32°F to
140°F (0°C to 60°C) for up to 30 days.

Using ACPI Power Control

Windows 98 provides ACPI (Advanced Configuration and Power
Interface), which is a system-wide approach to system and device
power control, as well as thermal management. ACPI enables the
operating system to respond to events and manage power for the
entire system and its devices. It makes the computer more
accessible by reducing boot time and allowing the computer to
wake up automatically. ACPI also incorporates power
management that reduces power consumption of the computer by
turning off the microprocessor and other components when
applications are idle or between keystrokes.

With ACPI, some Compaq power management features such as
power conservation settings in Computer Setup, battery
conservation popup windows, and initiating Hibernation will be
disabled.

For more information on ACPI functions, consult your Microsoft
Windows 98 reference guide.

5-6 Computer Power and Power Management

Using Hibernation

Hibernation is a safeguard feature that saves your information
when the computer reaches a low battery condition while it is left
unattended. When your computer hibernates, all the information in
system memory is saved to the hard disk and the power to the
computer is turned off. When you turn on the computer, your
information returns to the screen at the point where Hibernation
initiated. Hibernation behaves like a bookmark, and none of your
information is lost.

When Hibernation is initiated, it creates a file on the hard drive at
least equal in size to the amount of total random access memory
(RAM). If there is not enough space on the hard disk to store the
information, an insufficient disk space message is displayed.

Hibernation will automatically initiate as long as it is not disabled
(turned off) through the software. If you disable Hibernation and
the computer reaches a low battery condition, your unsaved
information will be lost.

CAUTION:

Using Timeouts

Timeouts are specified periods of system or component inactivity.
Timeouts work with battery conservation to conserve power.
When a timeout period has expired, battery conservation shuts
down the system or components in order to save power. For
example, the hard disk idle default timeout is two minutes.
Therefore, if an application does not access information on the
hard disk in less than two minutes, the hard disk shuts down until
it is accessed again.

Timeout values are set using the Battery Conservation Settings or
Hibernation tab in Power Properties (click Start Æ Control Panel

double-click Power Æ Power Properties). Using these utilities,

Æ

you can:

use the preset timeouts provided with the medium (default) or

■

high level of battery conservation.

 or

set your own component timeouts in conjunction with the

■

custom level of battery conservation so that the computer
works more efficiently with your applications.

Setting Component Timeouts

If you are running Windows 95, you can set your own timeout
values for individual components of the computer. To set
component timeouts:

1. Access the Power Properties utility by clicking Start Æ
Control Panel Æ double-click Power Æ Power Properties.

2. Click the Battery Conservation Settings tab.

3. Set the Battery Conservation level to Custom.

4. Using the drop-down boxes, select or type a timeout value for
specific components of the computer, such as system idle and
hard disk idle.

5. To save your settings, click OK when you are done. They
become effective immediately and remain in effect until you
change them.

SING THE INTERNAL

U

Modem Overview

The internal modem comes built into some models and is an
option for other models. It provides data communications and fax
functionality for applications running under Windows 95,
Windows 98, and Window NT 4.0. Preloaded software drivers are
required for modem operation and allow the modem to easily
communicate with software applications.

The internal modem supports standard analog modem
communication protocols (for speeds up to 33.6 Kbps) as well as
up to the ITU-compatible V.90 and industry standard K56flex
56K protocals for higher speeds.

IMPORTANT:

downloads only from V.90 K56flex compliant digital sources.
Maximum achievable download transmission rates are currently
unknown, may not reach 56Kbps, and will vary with line
conditions.

The V.90 and K56flex protocols allow faster

ODEM

M

Without having to make hardware changes, the modem may be
configured for operation in a variety of countries. An integrated
RJ-11 jack provides for simple connectivity to phone cables. If
accidentally plugged into a digital PBX phone outlet, the modem
automatically protects itself from excessive current until it is
plugged into an analog phone jack.

Using the Internal Modem 7-1

Connecting the Modem

To connect the modem to a standard telephone wall jack:

WARNING:

!

that the modem line is disconnected from the telephone network
when opening the equipments enclosure.

To reduce the risk of electrical shock, always ensure

1. Connect one end of the modem cable into the RJ-11 jack on
the right side of the computer.

IMPORTANT:

The internal modem uses a universal DAA
(Direct AccessArrangement) that supports multiple countries.
However, some countries may require an adapter to connect
the modem to the telephone wall jack.

The modem cable includes EMI suppression circuitry near the
end of the computer. For continued EMI emissions
compliance, plug that end of the cable into the computer.

2. Plug the opposite end of the cable into a standard telephone
wall jack.

IMPORTANT:

Wall jacks for digital PBX systems may resemble
standard telephone jacks but are not compatible with analog
devices such as modems. Be sure the modem cable is
connected to a regular analog phone line. Plugging the modem
into a digital line will result in no dial tone and is not
recommended. The modem includes protective circuitry
against the digital lines producing excess current.

Understanding How the Modem Works

The modem serves two major functions:

The data communications function allows your computer to

■

send information to and receive information from an online
service, a host mainframe computer that provides electronic
mail, and even other personal computers.

The facsimile function allows your computer to both send and

■

receive text and images from facsimile (fax) machines or other
computers.

7-2 Using the Internal Modem

After setting up your software, you are ready to start using your
modem. In most cases, if you are using communications and fax
software, the modem will be controlled by the software and you
will not need to use the AT command set. Simply select the
internal modem as the preferred communication device in your
application.

NOTE:

The maximum connection speed on a call is determined by
the speed of the slowest modem on the connection. Your modem
will automatically negotiate the fastest possible speed with the
remote modem.

Changing the Country Selection

The internal modem is configured to meet operating approval in
the country where you purchased your computer. If the modem is
used in other countries during travel, the country selection setting
for the modem needs to change to meet the telecommunications
regulations for that country.

The Country Select Application (CSA) lists all of the countries for
which the modem contains configuration information. To confirm
that the modem has been approved for use by the
telecommunications agency in the desired country, check the
approvals label on the bottom of the computer. Or, for the most
up-to-date information, refer to the Compaq Internet website at
www.compaq.com.

NOTE:

The internal modem supports specific countries that are
included in the selection list.

If you are running Windows 95 or Windows 98:

1. Click Start Æ Settings Æ Control Panel Æ double-click the
System icon.

2. Click the Device Manager tab.

3. Double-click modem icon, then double-click your modem.

4. Click the Country Setting for Modem tab, then select the
country from the List of Countries.

5. If you are traveling, click the Change Country button. While
traveling, you will be asked to confirm this setting at each
reboot. If you have permanently relocated to the country, click
the Home Country button, then click the Change Country
button.

6. Click Yes to confirm your country selection.

7. Click Yes to restart your computer.

Using the Internal Modem 7-3

If you are running Windows NT:

1. Click Start Æ Settings Æ Control Panel Æ double-click the
CSA Control Panel

2. Select the country from the List of Countries.

3. If you are traveling, click the Change Country button. While
traveling, you will be asked to confirm this setting at each
reboot. If you have permanently relocated to the country, click
the Home Country button, then click the Change Country
button.

4. Click Yes to confirm.

5. Click Yes to restart your computer.

NOTE:

When the Home Country and Current Country selections in
the CSA do not match, you will be prompted each time the system
restarts to confirm that the Country setting still reflects where the
modem is being operated at this time. To disable these reminders,
change the Home Country selection in the CSA to match the
Current Country. The Current Country setting should always be
set to the country in which the modem is currently being operated.

Software Overview

You need communications software to operate the modem. Such
software issues commands to the modem, including modem
connection speed, the number of rings before answering the
telephone, listening for a dial tone, and dialing a phone number.

For information on controlling the phone dialing sequence, refer
to “Dial Modifiers”. The internal modem, for example, includes
the ability to wait for a “go ahead tone” after dialing a credit card
number as part of the dialing sequence. To do this, add a $ symbol
at the appropriate point in the phone number string.

There is a wide range of communications software available that
can be used with this modem for tasks such as accessing your
computer from a remote location. Contact your Compaq
authorized dealer, reseller, or service provider for a complete list
of communications software applications.

IMPORTANT:

If Hibernation initiates or a low battery condition
occurs while your are using the modem with communications
software, the modem will disconnect. Exit Hibernation or resolve
the low battery condition, then restart the communications
software to restore the original modem settings.

Understanding Result Codes

A result code is a modem response to an issued command. The
screen displays the result code in one of two formats: the long
form, also known as verbose, or numeric characters represented by
digits. A typical example of a result code could be CONNECT

33600. This message is the modem’s acknowledgement that it has
established a connection at transfer rate of 33,600 bps.

Using AT Commands to Control the Modem

The internal modem can be used in a variety of applications and is
designed to interface with a wide range of computer and data
communications equipment. Because each device has specific
requirements of its own, the modem is equipped with an extensive
set of commands and registers that you can set to meet the specific
requirements of your system.

The modem always operates in one of two modes: the command
mode or the online mode. When power is turned on, the modem
automatically assumes the command mode. When the modem is in
the command mode, it can be configured for your computer
system or for a particular application.

You can use your communications software, such as Windows
HyperTerminal, to program the modem. In most cases, you can
merely select the options and operations required from a menu in
the communications software program. The communications
program transmits these selections to the modem in the form of
commands. The modem then processes the data received as
instructions to perform a particular task.

However, you can also issue commands directly from the terminal
mode of the communications program. Using the AT command
set, Class 1 fax extensions, and supporting S registers, you can
instruct the modem to perform a particular function or set of
functions. For example, you may instruct the modem to dial
(ATDn), answer (ATA), and hang up (ATH0) with the appropriate
commands.

You cannot enter commands when the modem is in the online
mode, that is, sending or receiving data over the telephone lines.
However, the modem returns to the command mode under the
following circumstances:

A call is disconnected, and the modem goes offline.

■

The modem cannot successfully complete a call, or if the data

■

carrier of the remote modem is dropped.
The modem receives a defined escape sequence or break

■

signal while in the online mode.
A semicolon (;) occurs at the end of a dialing string.

■

If an error occurs during the execution of a command line,
processing of the command line stops, and everything following
the erroneous command is ignored.

7-10 Using the Internal Modem

Guidelines for Using AT Commands

You must follow certain rules when entering or using the AT
command set. Read the topics in this section to learn more about
these guidelines:

Using the Attention Code

You should precede all commands except A/ and +++ with the
attention code AT.

Entering a Command

You can enter commands in uppercase or lowercase letters or a
combination of both. However, always type the AT prefix in the
same case (not At or aT).

You can enter a maximum of 60 characters for the internal modem
following the AT. The modem doesn't count the AT prefix,
carriage return (<cr>) character, or spaces. It counts, but doesn't
act on, punctuation, such as hyphens and parentheses.

You can enter telephone numbers with or without punctuation; for
example:

[phone] or 1234567890

However, punctuation in the telephone number takes up space in
the command buffer.

If a command sequence exceeds the 60-character maximum, the
modem does not execute any part of the command line and returns
an error message after the <cr> instead. If this occurs, reentering
the command within the 60-character limit allows the command
line to be executed.

Editing a Command

If you make an error while typing a command, simply backspace
over the mistake, then retype the line. You cannot backspace over
the AT prefix because it is interpreted immediately after it is
typed.

Executing a Command

After you enter an AT command, execute it with the Enter or <cr>
character (selected in register S3).

Using the Internal Modem 7-11

Interpreting a Missing Parameter

If you enter a command that normally includes a numeric
parameter (such as ATHn) without the numeric parameter, the
modem interprets the missing parameter as zero. For example, the
Hn (hang-up) command can have a numeric parameter of zero
(H0) or of one (H1); however, if the parameter is missing,
ATH<cr> is the equivalent of ATH0<cr>. This rule applies to
command parameters only, not to dial strings.

Entering an Escape Code Sequence

The escape code sequence (a 3-character code surrounded by
escape guard times) forces the modem from the online mode to the
command mode. You must enter the escape character three times
consecutively, and the delay between entering each escape
character must not exceed the escape guard time. After a short
delay, the modem responds with the OK result code to let you
know that it has successfully "escaped" to the command mode.
Use the ATO command to return to the online mode.

The escape guard time is defined as the time delay required
between the last character transmitted and the first character of the
escape code. The default escape character (set in register S2) is +,
the default escape guard time (set in register S12) is one second,
and the default escape code sequence is +++.

Repeating a Command

You can repeat the last command line issued by entering the A/
command. This action also repeats the AT prefix and the <cr>;
therefore, you are not required to enter the AT prefix or a <cr>
when using this command.

Each string command remains in the command buffer until an AT
is entered or power to the modem is turned off. Both actions clear
the buffer and make the A/ command invalid, since there is no
command for the modem to repeat.

Connecting Infrared Equipment

NOTE:

Infrared-equipped computers are IrDA-compliant. Infrared
performance may vary depending on peripherals, distance
between infrared devices, and applications used. The infrared port
is available only on specific models.

For infrared-equipped models, the infrared port allows wireless
communication between your computer and other infrared­equipped devices. Operating system support for infrared
communication is currently available with Microsoft Windows 95,
but not for Windows NT.

The infrared port produces an invisible beam of infrared light to
communicate with another infrared-equipped device.

To establish an infrared link:

Be sure the infrared ports on both computers are turned on and

■

facing each other at a distance no greater than 1.5 feet (about

0.5 meter).
Avoid moving the infrared ports away from each other during

■

data transmission.
Avoid interference from remote control units, such as wireless

■

headphones or audio devices, pointed at the infrared ports.
Avoid direct sunlight, fluorescent light, or flashing

■

incandescent light close to the infrared ports.
Keep the path between the infrared ports free of any objects

■

that might interfere with data transmission.
Do not point one of the ports more than 30 degrees (plus or

■

minus 15 degrees off the center line) away from the infrared
port of the device you are connecting with.

Connecting External Devices 8-5

Connecting USB Peripherals

Your computer comes equipped with a port that connects
Universal Serial Bus (USB) devices to the computer.

Your computer can support certain USB devices without any
special drivers. These include hubs and keyboards. For most other
USB devices without special drivers provided by the USB device
manufacturer, you will need an operating system which has USB
support for your device built in, such as Windows 95 OSR2.1 or
Windows 98. Later versions of the Windows operating systems
will add functionality which may allow you to attach any USB
device to your computer (for example, a video camera) and will
allow many USB devices to be connected and working
simultaneously.

A USB keyboard and mouse, optionally connected through a hub,
offer the same functionality as a standard keyboard and mouse
connected through the keyboard/mouse connector. Future
operating systems will have extended USB capabilities which will
replace the USB capabilities built into the computer.

PC Card Types

This computer can support two Type II cards or one Type III card.
It supports both 16-bit and CardBus (32-bit)
PC Cards. Several kinds of PC Cards are supported, such as
network cards, hard drive cards, memory cards, and fax/modem
cards.

For a current list of third-party PC Cards qualified on this
computer, call your Compaq authorized dealer, reseller, or service
provider.

Inserting a PC Card

1. If you are running Windows NT 4.0 but not CardWare 5.0
from Compaq, turn off the computer. If you are running
Windows 95, you do not need to turn off the computer or
initiate Suspend before inserting a PC Card.

NOTE:

from Compaq, insertion of the PC Card while the computer is
on is supported for most PC Cards. Contact your PC Card
vendor directly for information about the level of support they
offer for "hot insertion” with CardWare 5.0.

If you are running Windows 95 and your computer is on, the
computer automatically configures a plug and play card and most
other PC Cards. If the computer is turned off or in Suspend, a card
is not configured until you turn on the computer or exit Suspend.

Windows NT is not plug and play. If you are running Windows
NT, the computer configures a card only when it is in the PC Card
slot when the computer is turned on. The computer only
recognizes that a PC Card has been removed if the PC Card slot is
empty when the computer is turned on.

After the computer has configured the card, the computer beeps
twice to indicate that the card is ready for use.

IMPORTANT:

After the PC Card has been inserted and configured, it
may be necessary to perform an initial setup procedure. For
example, a new storage card may need to be formatted, or a new
network card may need drivers installed. For detailed information
on setup procedures for various Network PC Cards, refer to the
instructions provided by the PC Card manufacturer.

PC Card Device Drivers

Device drivers are programs or data files containing information
needed to run a specific PC Card. Most of the device drivers you
need are preinstalled on the computer.

NOTE:

In order to save available memory, some device drivers are

not enabled after being installed.
Some types of PC Cards, such as network cards, Global

Positioning System (GPS) cards, SCSI cards, audio cards, and
multifunction cards, require an additional PC Card-specific
software device driver to function properly. This software device
driver is provided on diskette by the PC Card manufacturer and
should be installed according to the manufacturer's instructions.
