Monitoring the charge of the battery pack
This section explains several ways to determine the amount of charge in a battery pack.
Obtaining accurate charge information
To increase the accuracy of all battery charge indicators:
●
Allow a battery pack to discharge to about 10 percent of a full charge through normal use before
charging it.
●
When you charge a battery pack, charge it fully before turning on the computer.
●
If a battery pack has been unused for one month or more, calibrate the battery pack instead of
simply charging it. For calibration instructions, refer to "
Calibrating a battery pack ."
Displaying charge information on the screen
This section explains how to access and interpret battery charge indicators.
Viewing charge displays
To view information about the status of any battery pack in the computer:
●
Double-click the Power Meter icon in the notification area, at the far right of the taskbar.
– or –
●
Select Start > Control Panel > Performance and Maintenance > Power Options > Power
Meter .
Interpreting charge indicators
Most charge indicators report battery status as both a percentage and as the number of minutes of
charge remaining:
●
The percentage indicates the approximate 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 when you start playing a DVD and will increase when you stop playing a DVD.
When a battery pack is charging, a lightning bolt icon may be superimposed over the battery icon on
the Power Meter screen.
