AC Adapter
Using the AC Adapter
The AC adapter converts AC power to the DC power required by the computer. The AC adapter kit includes two cables: the AC adapter cable and
an AC power cable.
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.
If the computer is docked to an advanced port replicator (APR), you can connect the AC adapter either to the computer or to the APR.
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 desk top 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.

2. Plug the AC adapter power cable into an electrical outlet.
3. Plug the AC adapter cable into the AC adapter connector on the computer.
