What is Smart Battery Calibration?
Repeated short discharges and recharges cause increasing inaccuracy between the state-of-charge of the battery and the Power Meter readings. Periodically, the battery needs to be calibrated to “relearn” its usable capacity so it can synchronize its charge status with the Power Meter. The calibration procedure maximizes the notebook run time by giving the user an accurate estimate of the remaining battery charge. Calibration also prevents data loss that can occur during the Hibernation process if sufficient power is not available to complete critical save-to-disk operations.
