  • Computer system capable of controlling the power supplied to specific modules
    Patent number: 6260151
    Abstract: In a computer system, a control signal line directly connecting a processor to a power sequence controller is provided and a PSC interface for exchanging a control signal with the power sequence controller is built in the processor. When all the devices connected to a specific IO bus have been out of use for a long time, the processor transmits a control signal to stop the supply of power to the IO bus to the power sequence controller. This stops power from being supplied to not only the devices connected to the IO bus but also the IO bus. As a result, the unnecessarily consumed power in the computer system is reduced remarkably.
