12 Quick Reference Guide

Using a Battery

Battery Performance

NOTE: For information about the Dell warranty for your computer, see the Product Information Guide or separate

paper warranty document that shipped with your computer.

For optimal computer performance and to help preserve BIOS settings, operate your Dell™ portable

computer with the main battery installed at all times. One battery is supplied as standard equipment in

the battery bay.

NOTE: Because the battery may not be fully charged, use the AC adapter to connect your new computer to an

electrical outlet the first time you use the computer. For best results, operate the computer with the AC adapter

until the battery is fully charged. To view battery charge status, access the Control Panel→ Power Options, and

then click the Power Meter tab.

NOTE: Battery operating time (the time the battery can hold a charge) decreases over time. Depending on how

often the battery is used and the conditions under which it is used, you may need to purchase a new battery during

the life of your computer.

Battery operating time varies depending on operating conditions. You can install an optional second

battery in the media bay to significantly increase operating time.

Operating time is significantly reduced when you perform operations including, but not limited to,

the following:

• Using optical drives

• Using wireless communications devices, PC Cards, ExpressCards, media memory cards, or USB devices

• Using high-brightness display settings, 3D screen savers, or other power-intensive programs such as 3D games

• Running the computer in maximum performance mode (see "Configuring Power Management

Settings" on page 16)

NOTE: It is recommended that you connect your computer to an electrical outlet when writing to a CD or DVD.

You can check the battery charge before you insert the battery into the computer (see "Checking the

Battery Charge" on page 13). You can also set power management options to alert you when the battery

charge is low (see "Configuring Power Management Settings" on page 16).

CAUTION: Using an incompatible battery may increase the risk of fire or explosion. Replace the battery only

with a compatible battery purchased from Dell. The lithium ion battery is designed to work with your Dell

computer. Do not use a battery from other computers with your computer.

CAUTION: Do not dispose of batteries with household waste. When your battery no longer holds a charge, call

your local waste disposal or environmental agency for advice on disposing of a lithium-ion battery. See "Battery

Disposal" in the Product Information Guide.

CAUTION: Misuse of the battery may increase the risk of fire or chemical burn. Do not puncture, incinerate,

disassemble, or expose the battery to temperatures above 65°C (149°F). Keep the battery away from children.

Handle damaged or leaking batteries with extreme care. Damaged batteries may leak and cause personal injury

or equipment damage.

Quick Reference Guide 13

Checking the Battery Charge

The Dell QuickSet Battery Meter, the Microsoft Windows Power Meter window and icon, the

battery charge gauge and health gauge, and the low-battery warning provide information on the battery

charge.

Dell™ QuickSet Battery Meter

If Dell QuickSet is installed, press <Fn><F3> to display the QuickSet Battery Meter. The Battery Meter

displays status, battery health, charge level, and charge completion time for the battery in your computer.

For more information about QuickSet, click the QuickSet icon in the Microsoft

®

Windows

®

taskbar,

and click Help.

Microsoft

®

Windows

®

Power Meter

The Windows Power Meter indicates the remaining battery charge. To check the Power Meter, double-click

the icon on the taskbar.

If the computer is connected to an electrical outlet, a icon appears.

Charge Gauge

By either pressing once or pressing and holding the status button on the charge gauge on the battery, you

can check:

• Battery charge (check by pressing and

releasing

the status button)

• Battery health (check by pressing and

holding

the status button)

The battery operating time is largely determined by the number of times it is charged. After hundreds of

charge and discharge cycles, batteries lose some charge capacity—or battery health. That is, a battery can

show a status of "charged" but maintain a reduced charge capacity (health).

Check the Battery Charge

To check the battery charge, press and release the status button on the battery charge gauge to illuminate

the charge-level lights. Each light represents approximately 20 percent of the total battery charge.

For example, if the battery has 80 percent of its charge remaining, four of the lights are on. If no lights

appear, the battery has no charge.

Check the Battery Health

NOTE: You can check battery health in one of two ways: by using the charge gauge on the battery as described

below and by using the Battery Meter in Dell QuickSet. For information about QuickSet, right-click the QuickSet

icon in the Microsoft

®

Windows

®

taskbar, and click Help.

14 Quick Reference Guide

To check the battery health using the charge gauge, press and hold the status button on the battery charge

gauge for at least 3 seconds. If no lights appear, the battery is in good condition, and more than 80 percent of

its original charge capacity remains. Each light represents incremental degradation. If five lights appear, less

than 60 percent of the charge capacity remains, and you should consider replacing the battery. See

"Specifications" in your online User’s Guide for more information about the battery operating time.

Low-Battery Warning

NOTICE: To avoid losing or corrupting data, save your work immediately after a low-battery warning. Then connect

the computer to an electrical outlet. If the battery runs completely out of power, hibernate mode begins automatically.

By default, a pop-up window warns you when the battery charge is approximately 90 percent depleted.

You can change the settings for the battery alarms in QuickSet or the Power Options Properties window.

See "Configuring Power Management Settings" on page 16 for information about accessing QuickSet or

the Power Options Properties window.

Conserving Battery Power

Perform the following actions to conserve battery power:

• Connect the computer to an electrical outlet when possible because battery life is largely determined

by the number of times the battery is used and recharged.

• Place the computer in standby mode or hibernate mode when you leave the computer unattended for

long periods of time (see "Power Management Modes" on page 14).

• Use the Power Management Wizard

to select options to optimize your computer’s power usage. These

options can also be set to change when you press the power button, close the display, or press <Fn><Esc>.

NOTE: See "Power Management Modes" on page 14 for more information on conserving battery power.

Power Management Modes

Standby Mode

Standby mode conserves power by turning off the display and the hard drive after a predetermined

period of inactivity (a time-out). When the computer exits standby mode, it returns to the same

operating state it was in before entering standby mode.

Charging the Battery

NOTE: With Dell™ ExpressCharge™, when the computer is turned off, the AC adapter charges a completely

discharged battery to 80 percent in about 1 hour and to 100 percent in approximately 2 hours. Charge time is longer

with the computer turned on. You can leave the battery in the computer for as long as you like. The battery’s internal

circuitry prevents the battery from overcharging.

When you connect the computer to an electrical outlet or install a battery while the computer is

connected to an electrical outlet, the computer checks the battery charge and temperature. If necessary,

the AC adapter then charges the battery and maintains the battery charge.

If the battery is hot from being used in your computer or being in a hot environment, the battery may

not charge when you connect the computer to an electrical outlet.

The battery is too hot to start charging if the light flashes alternately green and orange. Disconnect

the computer from the electrical outlet and allow the computer and the battery to cool to room

temperature. Then connect the computer to an electrical outlet to continue charging the battery.

For more information about resolving problems with a battery, see "Power Problems" in your online

User’s Guide.

Replacing the Battery

CAUTION: Before performing these procedures, turn off the computer, disconnect the AC adapter from the

electrical outlet and the computer, disconnect the modem from the wall connector and computer, and remove any

other external cables from the computer.

CAUTION: Using an incompatible battery may increase the risk of fire or explosion. Replace the battery only

with a compatible battery purchased from Dell. The battery is designed to work with your Dell™ computer. Do not

use a battery from other computers with your computer.

NOTICE: You must remove all external cables from the computer to avoid possible connector damage.
