Monitoring the Charge in a Battery Pack
Obtaining Accurate Charge Information
To increase the accuracy of all battery charge displays:
■ Allow the battery pack to discharge fully before charging it.
■ Charge the battery pack fully. Even a new battery pack can
display charge information inaccurately if it has not been
fully charged.
■ Fully charging and discharging the battery pack will reduce
the need for battery calibration.
Displaying Charge Information
To display battery charge information on the screen, select
Start
> Control Panel > Performance and Maintenance >
Power Options
> Power Meter tab.
Power Meter displays battery status in both percent and time:
■ The percent indicates the amount of charge remaining in the
battery pack.
■ The time indicates the approximate running time remaining
on the battery pack if the battery pack continues to provide
power at the current level. For example, the time remaining
will decrease if you start playing a DVD and will increase if
you stop playing a DVD.
Managing Low-Battery Conditions
You can change some low-battery condition alerts and system
responses using the Power Options window of the operating
system. The information in this section describes the alerts and
system responses set at the factory. Preferences set in the Power
Options window do not affect battery or power lights.
