Abstract
The apparatus includes an AC adapter input, a battery charger coupled to the input to charge a battery, a temperature sensor, and system logic to execute code stored on storage devices. The battery charger provides a charging current that is a function of temperature sensed by the temperature sensor. The charging current may also be a function of sensed barometric pressure, battery age, external temperature, a full charge capacity, and system power demand.
