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
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.
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.

Quick Reference Guide 13
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.
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 icon in
the 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 the specifications in your User’s Guide.
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.
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.
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.
NOTICE: You must remove all external cables from the computer to avoid possible connector damage.
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.
To remove the battery:
1
If the computer is connected to a docking device (docked), undock it. See the documentation that
came with your docking device for instructions.
2 Ensure that the computer is turned off.

Quick Reference Guide 15
3 Slide the battery-bay latch release on the bottom of the computer until the release clicks.
4 Using the tab on the battery, lift the battery out of the computer.
To replace the battery, place the battery in the bay and press down until the battery-bay latch release
clicks.
Storing a Battery
Remove the battery when you store your computer for an extended period of time. A battery discharges
during prolonged storage. After a long storage period, recharge the battery fully before you use it (see
"Charging the Battery" on page 14).
