FIELD: information technology.
SUBSTANCE: method comprises steps of: determining that the portable computing device (PCD) is docked with the PCD docking station; switching power supply to the PCD from a PCD battery to a PCD docking station battery in response to the determination that the PCD is docked with the PCD docking station; powering the PCD and the PCD docking station from the PCD docking station battery; determining whether PCD battery power equals a charge condition; charging the PCD battery from the PCD docking station battery when the PCD battery power equals the charge condition; monitoring PCD docking station battery power; determining whether the PCD docking station battery power equals a critical condition; and switching power supply to the PCD and PCD docking station from the PCD docking station battery to the PCD battery when the PCD docking station battery power equals the critical condition, and powering the PCD and PCD docking station from the PCD battery.
EFFECT: high efficiency of managing power distribution between a PCD and a PCD docking station.
