The AC adapter provides power for operating your LifeBook notebook and is used to charge the batteries.

Connecting the AC Adapter

1.Plug the DC output cable into the DC power jack of your LifeBook notebook.

2.Plug the AC cable into the AC adapter.

3.Plug the AC cable into an AC electrical outlet. (Figure 3-1)

Switching from AC Adapter Power to Battery Power

2.Unplug the AC adapter.

■When you run the N6400 Series Life- Book on battery power, by default, the CPU will slow down approximately by half in order to optimize battery life.

This feature can be enabled or disabled in the BIOS. Use an AC Adapter whenever possible.

■The Lithium ion battery is not charged upon purchase. Initially, you will need to connect the AC adapter to use your LifeBook notebook.
