A method and an apparatus for controlling a digital electronic product, using a control signal transmitter and a signal receiver combined with a gate system for controlling a digital home appliance, such that a system activation/inactivation control mechanism is established. The on/off status of the gate system is remotely controlled by the control signal transmitter. In the process of switching off the gate system, a basic input/output system (BIOS) for executing switching on/off is used to detect whether the external connecting port is connected to a signal receiver. When the system is in the off status, the electric connection to the signal receiver is maintained, such that the activation control signal from the control signal transmitter can be received any time. Thereby, the signal status of the signal receiver can be changed to automatically switch on the gate system, and the control signal transmitter can thus remotely control operation of the digital home appliance.
