Control Panel→ Power Options→

Quick Reference Guide 11

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.

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

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 3D games

• Running the computer in maximum performance mode. See "Configuring Power Management Settings" on page 14 for information about accessing Windows Power Options Properties or Dell QuickSet, which you can use to configure power management settings.

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, 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.

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.

A pop-up window warns you when the battery charge 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" on page 14 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 13).

• Use the Power Management Wizard or the

Power Options Properties

window 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 "Configuring Power Management Settings" on page 14 for information on conserving battery power.

Power Management Modes

Charging the Battery

NOTE: 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 User’s Guide.

Replacing the Battery

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: 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.

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

Quick Reference Guide 15

To remove the battery:

If the computer is connected to a docking device (docked), undock it. See the documentation that came with your docking device for instructions.

Ensure that the computer is turned off.

Slide the battery-bay latch lock on the bottom of the computer away from the battery.

Slide and hold the battery-bay latch release, and then remove the battery from the bay.
