Abstract

본 발명은 특히 퍼스널 컴퓨터의 동작중에 사용자가 잠시 자리를 비우거나 다른 작업을 하는 경우 모니터에 인가되는 전원을 자동으로 차단시킴으로써, 전력소모를 감소시킬 수 있는 컴퓨터의 전원 제어 방법에 관한 것으로, 일반적으로 퍼스널 컴퓨터의 사용자는 컴퓨터의 전원을 한번 턴-온시키면, 컴퓨터를 사용하다가 컴퓨터를 끄지 않은채 잠시 자리를 비우거나 다른 작업을 하는 경우가 많으므로, 종래에는 이러한 경우 컴퓨터에 항상 전원이 공급됨으로써, 불필요하게 컴퓨터가 많은 전력을 소모하게 되는 문제점이 있었다.In particular, the present invention relates to a power control method of a computer that can reduce power consumption by automatically shutting off the power applied to the monitor when the user is temporarily away from the computer or performing other tasks during the operation of the personal computer. When a user of a personal computer turns on the computer once, it is often used to leave the computer for a while or do other work without turning off the computer. Unnecessarily, the computer consumes a lot of power.

본 발명은 이와같은 종래의 문제점을 감안하며, 퍼스널 컴퓨터의 전원이 턴-온되어 있는 상태에서 타이머 칩을 사용하여 입력 장치인 키보드와 마우스가 일정시간 사용되지 않았을 때에는, 타이머 칩으로부터 제어 신호가 발생하도록 하여 모니터에 인가되는 전원을 차단시킴으로써 전력소모를 감소시키고, 또 모니터에 인가된 전원이 차단되었을 경우, 키보드나 마우스 입력이 들어오면 다시 모니터에 인가된 전원을 연결함으로써, 자동으로 컴퓨터의 전원을 제어토록 한 것이다.SUMMARY OF THE INVENTION The present invention contemplates such a conventional problem, and when a keyboard and a mouse, which are input devices, are not used for a certain time by using a timer chip while a personal computer is turned on, a control signal is generated from the timer chip. By reducing the power supply to the monitor, and reducing the power consumption, when the power supply to the monitor is cut off, when the keyboard or mouse input comes in, the power supply to the monitor is reconnected to automatically turn on the computer. To control it.
