Abstract
A system and a method for power control are provided. In the present invention, a control switch is disposed in a power adapter, which is turned on/off by a monitoring device disposed in a portable electronic device. As a result, the power inputted into the power adapter can be controlled, and thus the power consumption during the portable electronic being shut down is reduced. In addition, the present invention controls the power providing for a battery according to a detected power on/off signal and the electric quantity of the battery. The control switch is turned off to stop the power adapter from providing power when the electric quantity of the battery reaches a reference value. Therefore, the overheating situation of the portable electronic device or the battery that may shorten their service life because of continuing receiving power can be avoided.
