Abstract
A power control apparatus and method for an electronic device is provided, which utilizes a charge current control module and a feedback signal control module to transfer the power control signal to a remote-controlled adapter through a feedback circuit, to control the output voltage of the remote-controlled adapter so as to adjust the charge current until the total input current supplied by the remote-controlled adapter is equal to the highest total input current. Therefore, the system of the electronic device can be provided with sufficient power to process needed procedures in a safe condition. Besides, according to the power required by the system of the electronic device, the controller can distribute the power for both the system and the battery in order to improve the efficiency of power use.
