Battery Disposal
When your battery no longer holds a charge, call your local waste disposal agency or environmental agency for advice on disposal of the
computer
’s lithium-ion battery.
About Battery Power
You automatically conserve battery power each time you attach the computer to an electrical outlet. The battery is even being recharged when you
use AC power. The battery's life expectancy is largely determined by the number of charges it receives, so use an electrical outlet to run the
computer whenever possible.
You can customize power management by individually controlling the computer's power conservation features. These features reduce power
consumption by monitoring application programs and computer devices for inactivity and slowing down or stopping some of the computer
’s
internal devices.
Experiment with power conservation features to achieve the optimum power conservation for your work environment.
Turning the Computer On
To turn on the computer, press the power button.

CAUTION: Do not puncture or incinerate the battery.
NOTES: This computer is supplied with a lithium-ion or a nickel-metal hydride battery, which is significantly less
hazardous to the environment than the lithium metal technology used in some other batteries (such as watch batteries).
Lithium-ion and nickel-metal hydride batteries are longer lived than conventional batteries and do not require
replacement as often. Do not dispose of these batteries along with common household waste. Contact local authorities for
the location of a chemical waste collection program nearest you. To purchase a new battery, call Dell or access the Dell
World Wide Web site at http://www.dell.com.
NOTES: When you use power conservation features, you often trade some of the performance of the computer for
increased battery operating time. For example, if you turn off the hard-disk drive, you may experience a delay the next
time the computer tries to access the hard-disk drive.
Other power conservation features, such as standby mode, stop almost all system activity. They allow you to maximize
power conservation when your work is interrupted.
NOTE: If your computer's operating system is "locked up"—that is, it does not respond to commands—press and hold
down the power button for at least 5 seconds to turn it off.
