Abstract

A portable docking and precharging station with an AC adapter with automatically optimized output voltage and power. An IIC communications link between the computer and AC adapter carries signals which adjust the AC adapter's voltage and power settings, depending on the charge state of the battery and whether the computer is on or off. If the computer is on, full output power is provided from the AC adapter. If the computer is off, the output power from the AC adapter is reduced so that the current cannot exceed the battery manufacturer's recommended charging rates. Preferably the regulated output voltage and the current limit are both changed when the change between modes occurs.
