C A U T I O N
The primary Lithium ion battery is not fully
charged when you purchase your note -
book. Initially you will need to connect the
AC adapter or the auto/airline adapter to
use your notebook. If you purchase a sec-
ond Lithium ion battery it will not be
charged when you get it. You will need to
charge it prior to use. It can take up to four
(4) hours to charge a single battery if your
notebook is turned off or is in Suspend
mode. If your notebook is in use it can take
up to nine (9) hours or more to charge a
single battery.
P O I N T
The higher the brightness level, the more
power the notebook will consume and
the faster your batteries will discharge. To
maximize battery life refer to section 7.
