If the notebook you are servicing has an unknown password, follow these steps to clear the password. These steps also clear CMOS.

1.Prepare the computer for disassembly. Refer to Section 5.3, “Preparing the Computer for Disassembly,” for more information.

2.Remove the disk cell RTC battery (refer to Section 5.15, “Disk Cell Real Time Clock (RTC) Battery”).

3.Wait approximately five minutes.

1–8	Maintenance and Service Guide

Product Description

4.Reassemble the computer.

5.Connect AC power to the computer. Do NOT reinsert the battery pack at this time.

6.Turn on the computer.

7.All passwords and all CMOS settings are clear.

1.3Power Management

The computer operating system provides power management utilities that help maintain and conserve power when the computer is running on battery power.

To access power management options, select the power application icon in the operating system’s Control Panel.

Enabling Power Savings

The Enable Power Savings feature in Power Management controls all power management features. When set to disabled, the power menu is automatically disabled. The default setting is enabled.

Timeout Settings

Timeout functions can be set up to power down computer components by selecting the Power Schemes tab from the power application in the operating system’s Control Panel. When a component such as the monitor, hard drive, system, or video is not in use, the component powers down to conserve power. The time out interval can be set from one minute up to several hours. The component will power up again when you access it or press any key.

Maintenance and Service Guide

Product Description

Setting Standby

Standby is initiated by pressing the Fn+F4 hotkeys or automatically by the computer if it reaches the defined percentage of battery pack power remaining. When Standby is initiated, several subsystems will power off to conserve energy. The system will wake up from Standby when a key is pressed. Although the Standby mode maintains the information and opens the file upon wake-up, any unsaved information is lost if the computer is turned off before ending Standby.

Hibernation

Hibernation is an energy-saving feature and safeguard that saves information in RAM to a hibernation file on the hard drive, then shuts down the computer. Hibernation is initiated by the computer when the computer reaches the defined percentage of battery pack power remaining. To wake the computer from Hibernation, press the power button. When you resume work, the information returns to the screen where you left off.

The computer uses the operating system with a power management utility that helps you maintain and conserve power when the computer is running on battery power.

Standby

Standby is an energy-saving feature that conserves power and reduces startup time.

Standby reduces power to system components that are not being used. Standby can be initiated by you or by the system. When Standby is initiated, all work is saved in random access memory (RAM) and the screen is cleared. When work is resumed, the information returns to the screen.

Refer to Section 1.4 in this chapter to identify the Power, Standby, and Hibernation controls.

Product Description

1.4 Design Overview

This section presents a design overview of key parts and features of the computer. Refer to Chapter 3, “Illustrated Parts Catalog” and Chapter 5, “Removal and Replacement Procedures.”

The system board provides the following device connections:

■Memory expansion board

■Hard drive

■Display

■Keyboard/TouchPad

■Audio

■Intel Pentium III or Intel Celeron Processors

■Fan

■PC Card

■Modem or modem/NIC

■Microphone

The computer uses an electrical fan for ventilation. The fan is controlled by a temperature sensor and 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 right side of the computer.

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

Troubleshooting

ÅWARNING: Only authorized technicians trained by Compaq should repair this equipment. All troubleshooting and repair procedures are detailed to allow only subassembly/module level repair. Because of the complexity of the individual boards and subassemblies, no one should attempt to make repairs at the component level or to make modifications to any printed wiring board. Improper repairs can create a safety hazard. Any indication of component replacement or printed wiring board modification may void any warranty or exchange allowances.

Utilities that are preinstalled on the computer include:

■PhoenixBIOS Setup Utility—Allows you to modify or restore factory default settings and configure the system BIOS to diagnose and solve minor problems.

■Power Management—Allows you to reduce your computer power consumption. Power Management information is contained in Chapter 1.

■Security—Allows you to set or remove your power-on password. Security information is contained in Chapter 1.
