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
(see Figure 2-1).
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.
