A method and device for remote access of power control system of a set-top box allowing for a cable or satellite operator to activate the main power supply of a cable box from a remote location. An externally generated signal is received at the set-top box in standby mode. In one embodiment, if the externally generated signal requires decoding, the externally generated signal is then decoded to determine whether it is for activating the main power supply. If the externally generated signal is for activating said main power supply, the main power supply is activated, placing the set-top box in active mode. Activating the main power supply operates to provide power to the main circuitry. In one embodiment, once the main circuitry is provided with power, the set-top box can receive externally generated information, such as program information and emergency alerts. In another embodiment, once the set-top box is done receiving the externally generated information, the set-top box determines whether a user has interacted with the set-top box since the main circuitry has been activated. If there has been no user interaction with the set-top box since the main circuitry has been activated, the main power supply is deactivated, returning the set-top box to standby mode.
