The Power Sources

The computer can be powered by either an AC/DC adapter or a battery pack.

AC/DC Adapter

Use only the AC/DC adapter that comes with your computer. The wrong type of AC/ DC
adapter will damage the computer and its components.
1. Attach the AC/DC adapter to the DC-In jack at the rear of the computer.
2. Plug the AC power cord into an outlet, and then connect the AC power cord
to the AC/DC adapter.
3. Raise the lid/LCD to a comfortable viewing angle.
4. Press the power button to turn "On".

Battery

The battery allows you to use your computer while you are on the road or when an
electrical outlet is unavailable. Battery life varies depending on the applications
and the configuration you're using. To increase battery life, let the battery discharge
completely before recharging. We recommend that you do not remove the battery.
