Calibrating a Battery Pack

Calibration increases the accuracy of all battery charge displays.
The calibration utility supports all battery packs that can be used in the
computer.
Use the calibration utility both to check the calibration of a battery pack and to
calibrate or recalibrate a battery pack.
A battery pack cannot be calibrated unless the utility reports that it needs
calibration.
While a battery pack is being calibrated, it is fully charged, then fully
discharged.
In Windows 98 select StartÅSettingsÅControl PanelÅ Power
ManagementÅPower Meter tab.
A new battery pack can be charged, then used to run the computer
before the battery pack is calibrated. However, the amount of charge
in the new battery pack cannot be reported accurately until the new
battery pack has been calibrated.
Check the calibration of a used battery pack periodically and
whenever battery charge displays seem inaccurate.
A battery calibration icon in the taskbar displays an Up arrow during
the charge phase and a Down arrow during the discharge phase.
A calibration cannot resume if the calibration is stopped or if the
computer is shut down during a calibration. An interrupted
calibration must be restarted.
After calibration, a battery pack must be charged before it can be
used to run the computer.
