AC Adapter
The AC adapter converts AC power from an electrical outlet to the DC power used by the computer. The AC adapter kit includes the AC adapter
with its attached DC cable (which connects to the computer) as well as an AC power cable that connects the adapter to an electrical outlet.
You can connect the AC adapter with your computer either turned on or off.
The AC adapter works with electrical outlets worldwide. However, power connectors vary among countries. Before you use AC power in a foreign
country, you may need to obtain a new power cable designed for use in that country.
NOTE: If you are running your computer on AC power with a battery installed, the AC adapter charges the battery (if needed) and then
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.
Connecting the AC Adapter
1. Connect the AC adapter's attached cable into the computer's AC adapter connector (see Figure
2. Plug the AC adapter power cable into the other end of the AC adapter.
3. Plug the AC adapter power cable into an electrical outlet.

Batteries
Your computer includes a 4-cell or 6-cell lithium ion battery that provides power when an electrical outlet is not available. The battery is installed on
the underside of the computer and forms part of the bottom of the computer. Lithium ion batteries are longer lived than conventional batteries and
do not require replacement as often. You do not need to drain a lithium ion battery completely before recharging it.
Do not place spent batteries with common household waste products. See
Keep the following information in mind when you are running your computer from the battery:
A fully charged 6-cell, 34-watt-hour (WH) battery provides approximately 2 hours of battery life; a fully charged 4-cell, 23-WH battery provides
l
approximately 1 hour of battery life. Actual performance varies, depending on which power management features are enabled and which
application programs you are using.
