Customizing Your Notebook Computer
Controlling Power Management
The PowerPanel utility allows you to control the power management of
your notebook computer and provides key information about system
activity and battery life. The following sections briefly describe how to
conserve your computer’s battery power. You can also refer to the
PowerPanel Help for more detailed information.
Power Management Profiles
PowerPanel provides several predefined power management profiles.
Each profile consists of a group of specific power management settings
that are designed to meet specific power management goals—ranging
from maximum power management to no power management. You can
change the settings for any of the predefined profiles or you can create
your own profile to suit your portable computing needs. The predefined
profiles are:
