■
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.
