AC Adapter
The AC adapter kit includes the AC adapter and an AC power cable.
If you are running your computer on AC power with a battery installed, the AC adapter charges the battery (if needed) and then maintains its charge.
Battery
The computer supports up to 2 lithium ion batteries simultaneously. The main battery is a standard feature and is used in the battery compartment; an optional
secondary battery can be installed in the options bay.
Either battery can power the computer by itself. When 2 batteries are installed, the computer draws power from both of them serially. The lithium ion battery has a life
span of up to 500 full charges when it is charged at normal room temperature.
A number of factors affect battery operating time :
l The power conservation features used
l The number and type of PC Cards used
l The kinds of application programs run
l The capacity of the optional memory modules installed (the higher the capacity, the more power used)
l The use of a CD-ROM or DVD-ROM drive, which uses more power than a hard-disk drive or a diskette drive

Charging the Battery
Each time you connect the computer to AC power or install a battery in a computer that is connected to AC power, the computer checks the battery's charge and
temperature. The AC adapter charges the battery (if necessary) and maintains the battery's charge.
NOTICE: The AC adapter should be in a ventilated area, such as on a desktop or on the floor, when used to power the computer or charge the battery.
Do not use the AC adapter in a poorly ventilated environment, such as inside a carrying case.
NOTICE: The AC adapter works with AC power sources worldwide. However, electrical outlets vary between countries. Before using electrical outlets
outside of the U.S., you may need to obtain a power cable designed for use in that country.
NOTICE: The AC adapter is designed to work only with Dell Inspiron portable computers. Do not use adapters from other computers, and do not
attempt to use this adapter with other computers.
