While a battery pack is being calibrated, it is fully charged, then fully discharged.

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.

The calibration utility calibrates one battery pack at a time and can run in the background as you use the computer or overnight.

CAUTION: To prevent loss of work, ensure that the computer remains connected to AC power throughout a calibration.
