SING BATTERY PACKS

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.

Using Battery Packs 4-1

WARNING:

There is a risk of fire and burns if the battery pack is not handled properly. Do not disassemble, crush, puncture, short external contacts, or dispose of in fire or water. Do not expose to temperatures higher than 60qC. Replace only with the Compaq spare designated for this product.

Your computer contains a Lithium Ion battery pack.

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.

CAUTION:

high temperatures for extended periods of time.

To prevent damage to a battery pack, do not expose it to

Maximizing Battery Pack Life

Battery pack operating time varies depending on the system components, options, and applications used. You can increase battery operating time by as much as 50 percent by controlling the energy used by the computer and the energy stored in the battery pack.

Using Advanced Power Management

In Windows 95, some Windows applications require that Advanced Power Management (APM) be enabled in order to run effectively. APM, which is enabled by default on your computer, automatically reduces power consumption behind the scenes, saving power while you work. For example, APM turns off the microprocessor between keystrokes and when your applications are idle.

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.

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.

SING THE INTERNAL MODEM

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.

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.

The V.90 and K56flex protocols allow faster

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.

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

IMPORTANT:

(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:

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.

To reduce the risk of electrical shock, always ensure

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:

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:

Using the Internal Modem 7-9

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:

(123) 456-7890 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.

S Register Default Values

The S register default values are set to function appropriately under most circumstances. However, their values may be modified if necessary. For example, it may take an especially long time to get a dial tone in your office, so you may choose to reset S6 for a longer wait time.

Using the Internal Modem 7-15

Modifying an S Register

The correct command format for modifying an S Register is ATSn=r, where n is the register number to be modified and r is the value to which you wish to set the register. For example, to set register 37 to 7, enter:

ATS37=7<cr>

The register S37 is now set to a value of 7.

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 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:

If you are running Windows NT and CardWare 5.0 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. Do not install any other PC Card software on the computer such as Card and Socket Services, even if prompted to do so.

CAUTION:

the computer. If you install card and socket services or enablers provided by other vendors over software preinstalled on the computer, the computer may no longer work properly with all of your PC Cards.
