Once you have started charging the battery pack, do not use
it until it is fully charged.

Turn off the computer whenever it is not in use.
To save battery power:
•
Use Advanced Power Management (APM)

•
Use the Battery Power-Management function
The computer has power-management functions built in. No special
power-management drivers have to be installed before you use the
computer. However, the computer is able to conserve more power
when Advanced Power Management (APM) is used.
APM allows you to reduce power consumption when your
applications and devices are idle. Each operating system comes
with its own APM.
