Using the AC adapter
The power to run your computer can come either from the lithium-ion (Li-ion)
battery pack provided with it, or from AC power through the AC adapter. While you
use AC power, the battery charges automatically.
The AC adapter that comes with your computer has two basic components:
1. The transformer pack that converts AC power for use with the computer.
2. The power cord that plugs into the AC outlet and into the transformer pack.
CAUTION
Using an improper power cord could cause severe damage to your computer.
To use the AC adapter, do the following. Be sure to take these steps in the order in
which they are given here.
1. Connect the AC adapter to the AC power adapter jack of the computer.
2. Connect the power cord to the transformer pack.
3. Plug the power cord into an electrical outlet.
You can check the status of your battery at any time by looking at the battery meter
at the bottom of your display.
Note:
v When you do not use the AC adapter, disconnect it from the electrical outlet.
