Understanding Battery Calibration
Calibration increases the accuracy of all battery charge displays.
It should not be necessary to calibrate any battery pack
frequently, even if it is heavily used. It is not necessary to
calibrate a new battery pack before first use.
Calibrate an in-use primary MultiBay battery pack if:
■
Battery status displays seem inaccurate.
■
The battery has not been used for one month or more.
Also note the following before starting calibration:
■
A battery pack must be calibrated in the notebook. If the
calibration utility reports that a battery pack in a mobile
expansion unit needs calibration, remove the battery pack and
insert it into a notebook battery bay or MultiBay before
running the calibration utility.
■
The notebook cannot be used during calibration, but a
calibration can run overnight unattended.
■
A calibration cannot be stopped or interrupted.
■
The notebook must be connected to an AC outlet throughout
the calibration. Do not disconnect the notebook from the AC
outlet until:
❏
The utility reports that calibration is complete, and
❏
The battery light turns off.
■
A battery pack can only be calibrated if the Computer Setup
utility reports that it needs calibration.
