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 Start→ Settings→ Control Panel→ Power
Options→ Power Meter.
Quick Reference Guide 11
WR559cbk0.book Page 12 Tuesday, December 12, 2006 9:42 AM
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, Express Cards, 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 (
management settings in your User’s Guide)
You can check the battery charge (see "Checking the Battery Charge" on page 12) 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 information on configuring power management settings in your User’s Guide).
see information on configuring power
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 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.
Microsoft Windows Power Meter
The Windows Power Meter indicates the remaining battery charge. To check the Power Meter, doubleclick the icon on the taskbar.
If the computer is connected to an electrical outlet, a icon appears.

WR559cbk0.book Page 13 Tuesday, December 12, 2006 9:42 AM
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
• Battery health (check by pressing and
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
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, and 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. See your User’s Guide for information about accessing
the Power Options Properties window.
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.
Quick Reference Guide 13
WR559cbk0.book Page 14 Tuesday, December 12, 2006 9:42 AM
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 your 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.
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.
NOTICE: If you choose to replace the battery with the computer in standby mode, you have up to 1 minute to
complete the battery replacement before the computer shuts down and loses any unsaved data.
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.
3
Slide and hold the battery-bay latch release on the bottom of the computer, and then lift the battery
from the bay.
1 battery-bay latch release 2 battery
To replace the battery, follow the removal procedure in reverse order.
