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, click the Start button→ Settings→ Control Panel→

Power Options→ Power Meter tab.

14 Quick Reference Guide

You can install an optional second battery in the media bay to significantly increase operating time. For

additional information about using a second battery, see "Media Bay" in the online User’s Guide for your

computer.

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. 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

complex 3D graphics applications

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

Settings" in the online

User’s Guide

for your computer.)

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 (see "Checking the Battery Charge" on page 14) before you insert the

battery into the computer. You can also set power management options to alert you when the battery

charge is low

(see "Configuring Power Management Settings" in the online

User’s Guide

for your 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.

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.

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, right-click the icon in the taskbar, and click Help.

Quick Reference Guide 15

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.

16 Quick Reference Guide

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

the taskbar, and click Help.

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 "Battery" 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, or install a second battery in the media bay. If the battery runs

completely out of power, hibernate mode begins automatically.

The battery status light on the hinge cover (at the lower-right corner of the display) flashes orange when

the battery charge is low, and it is solid orange when the battery charge is critically low. Also, a pop-up

window warns you when the battery charge is approximately 90 percent depleted. If two batteries are

installed, the low-battery warning means that the combined charge of both batteries is approximately

90 percent depleted. The computer enters hibernate mode when the battery charge is at a critically low

level.

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

See

"Configuring Power Management Settings" in the online

User’s Guide

for your computer.

Charging the Battery

NOTE: With Dell™ ExpressCharge™, the AC adapter charges a completely discharged battery in approximately

1 hour with the computer turned off. Charge time is longer with the computer turned on. You can leave the battery in

the computer as long as you like. The battery’s internal circuitry prevents the battery from overcharging.

NOTE: If you want to use Dell ExpressCharge with a 9-cell battery, you need to use it in conjunction with a 90-W

AC adapter.

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.

Quick Reference Guide 17

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.

For information about replacing the second battery, if applicable, see "Media Bay" in your online User’s

Guide.
