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
