1-4 Product Description

Intelligent Manageability

Intelligent Manageability consists of preinstalled software tools for the computer and Compaq servers that assist in tracking, troubleshooting, protecting, and maintaining the computer. It provides the following functions:

■ Asset Management—provides detailed configuration and diagnostic information.

■ Fault Management—prevents, predicts, and alerts of impending hardware

problems.

■ Security Management—protects unauthorized access to data and components.

■ Configuration Management—optimizes the computer by providing the latest

drivers, utilities, and software, which are available on CD-ROM and the Compaq Web site at www.compaq.com/support/portables.

NOTE: For further help with Intelligent Manageability, select Start ➔=Compaq Information Center ➔ Intelligent Manageability

Accessing the Web Agent

The computer may have a preinstalled Web Agent that allows computer configuration information to be viewed using Web technology. To access this feature, select Start ➔ Compaq Information Center ➔ Insight Web Management.

If the computer does not have a preinstalled Web Agent, it can be downloaded from the Compaq Web site at www.compaq.com.

Product Description 1-5

Asset Management

AssetControl enables component information to be retrieved when on the road or connected to the network.

AssetControl also enables the network administrator to remotely retrieve information from any Compaq computer connected to the network. The information can be used to assist in tracking and maintaining the computer and its components. It provides the following information:

■ Inventory information—The network administrator can retrieve information about the computer over the network by using Compaq Insight Manager or any PC management tool provided by Compaq Solution Partners. Asset control information retrieved from the computer includes:

■ Manufacturer, model, and serial number of Compaq computers, monitors, hard

drives, battery packs, memory boards, processor speeds, and operating systems

■ Asset tag

■ System board and ROM revision levels

■ BIOS settings

■ Diagnostic information—Diagnostics for Windows includes information on hard

drives, ports, and video, sound, and other components. This application also allows the user to run multithreaded tests on hardware components. If problems are found, recommendations are provided.

All of the above information can be viewed, printed, or saved.

1-6 Product Description

Fault Management

Fault Management features minimize downtime and data loss by monitoring system performance and generating the following alerts:

■ Hard drive alert—provides 72-hour advance warning of impending hard drive problems and can automatically start optional backup software.

■ System temperature alert—reports overheating. As the system temperature rises, this feature first adjusts fan speed and other cooling components, then displays an alert, then shuts down the system.

■ Battery pack alert—reports charging problems and battery pack failure.

■ Monitor alert—diagnoses and displays external monitor operational problems.

■ Memory alert—reports memory board configuration changes when a memory

board is removed, added, or reconfigured. It also provides the previous and current configurations for comparison.

The alerts work with or without network connection. If the computer is not connected to the network, the network administrator cannot receive alerts from the computer.

Fault Management Alerts

Alerts can be enabled, disabled, and tested, and software can be set to back up information whenever a hard drive alert occurs.

■ While the computer is connected to a network, alerts pop up on the computer display and are simultaneously reported to the network console.

■ When the computer is not connected to a network, the user will receive a local alert.

To set alerts, select the Intelligent Manageability icon in the system tray.

Product Description 1-7

Security Management

Security Management features customize system security.

■ Power-On and Setup Passwords—prevent unauthorized access to information and computer configuration.

■ DriveLock—prevents unauthorized access to hard drives.

■ Device disabling—prevents unauthorized data transfer through modems, serial

ports, parallel ports, and infrared ports on the computer and an optional docking station.

■ QuickLock/QuickBlank—locks the keyboard and clears the screen.

■ Ownership Tag—displays ownership information during system restart.

Configuration Management

Configuration Management optimizes software upgrade and customer support procedures. Compaq provides support software to optimize the performance of the computer. This support software is accessible through a monthly CD-ROM subscription. Support software can also be downloaded from the Compaq Web site at www.compaq.com/support/ portables.

Managing Power

The computer comes with a collection of power management features that allow battery operating time to be extended and power to be conserved. Use power management to monitor most computer components such as the hard drive, processor, and display.

Accessing Power Management

In Windows 95, select StartSettingsControl PanelPower to view or adjust settings in Power Properties.

NOTE: If Windows NT 4.0 is running, select Compaq Power instead of Power. If

Windows 98 is running, select Power Management.

Power Management Levels

To extend the life of batteries, use the Battery Conservation tab in Power Properties. If Windows 95 is running, select Start  Settings  Control Panel  Power to access Power Properties.

NOTE: If Windows NT 4.0 is running, select Compaq Power instead of Power. If

Windows 98 is running, select Power Management.

1.4 Design Overview

This section presents a design overview of key parts and features of the computer. For assembly/disassembly instructions for the parts described in this section, refer to Chapter 5.

System Board

The system board provides the following device connections:

■ Memory expansion board

■ MultiBay device

■ Hard drive

■ Display

■ Keyboard/EasyPoint IV pointing device or touchpad

■ Audio

■ Pentium II processor

■ Fan

■ PC Cards

■ Modem

The computer is equipped with an Intel Mobile Pentium III 500-MHz or Intel Mobile Pentium II 400-MHz processor. For ventilation, an electrical fan is installed. The fan operates on from 5 to 12 volts and is controlled by a temperature sensor. The fan is designed to turn on automatically when high temperature conditions exist. These conditions are affected by high external temperatures, system power consumption, power management/battery conservation configurations, battery fast charging, and software applications. Exhaust air is displaced through the ventilation grill located on the left side of the computer.

CAUTION: To properly ventilate the computer, allow at least a 3-inch (7.6-cm) clearance on the left and right sides of the computer.
