Battery Packs

Hardware Guide

3–5

Charging the battery pack prolongs battery life and increases the 
accuracy of the battery gauge. When charging the battery:

■

Allow the battery pack to fully discharge before charging it.

■

Charge the battery pack fully. Even a new battery pack can 
display charge information inaccurately if it has not been 
charged fully.

■

Fully charging and discharging the battery pack will reduce 
the need for battery calibration.

■

A battery pack in a notebook that has been idle for over 
one month might need calibrating. See 

To see the amount of charge remaining in the battery pack:

»

Select Start > Control Panel > Performance and 
Maintenance > Power Options > Power Meter.

✎

If the Power Meter icon is placed on the taskbar, it will change 
shape according to whether a battery pack or AC power is the 
primary power source.

Most battery charge displays report battery status in terms of 
percent of charge remaining and run time remaining.

The run time remaining indicates the approximate running time 
left if the battery pack continues to provide power at the current 
level. For example, battery run time will decrease if you start 
playing a DVD and will increase if you stop playing a DVD.
