ABSTRACT:
In a computer system, the supply of a source voltage to a main computer block is started by using a reset switch provided for resetting the main computer block and cut off by specific key input signals from a keyboard or by programming in the computer. The main computer block includes a switching mode power supply SMPS for providing an operating power and a stand-by voltage to the main computer block, a power-on signal generator for generating a power-on signal to the SMPS by the reset switch, and a power-off signal generator for generating a signal for inverting the power-on signal generated from the power-on signal generator to a power-off signal.
