ABSTRACT:
In a personal computer having a logic circuit constituted by low-power consumption elements such as CMOS elements, a power saving system includes a register in which control data can be set from a keyboard or by software, and switches for allowing and stopping power supply from a power supply to an oscillator on the basis of control data from the register. Supply of clock signals to a disabled logic circuit can be stopped by an operator's decision. In initialization processing of a driver routine of an extended card optionally connected to the personal computer, power supply designation information is set in the register. In the completion routine, power supply stop designation information is set in the register.
