An apparatus and its corresponding method for blocking user input are provided. The apparatus comprises a reset unit, a detecting unit, a logic controlling circuit and a switch element. The reset unit outputs a reset signal in response to a voltage level of a power supply and an external voltage signal of the power supply. The detecting unit outputs a level indicator signal in response to the voltage level and a basic indicator signal provided by a system core. The logic controlling circuit outputs a switching signal in response to the external power signal provided by the power supply, an operation mode signal provided by the system core, the reset signal, and the level indicator signal. The witch element connects or disconnects the system core and an input device in response to the switching signal.
