Power 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: ■ 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. 2-18 Software Guide
