Abstract

본 발명은 컴퓨터의 전원오프장치에 관한 것이다. 종래의 컴퓨터의 전원 오프장치는 전원공급장치를 온하는 것은 시스템을 사용하기 위하여 어쩔 수 없으나, 시스템을 장시간 사용하게 되면, 사용자가 피로를 느끼게되며, 이 상태에서 전원을 물리적인 힘을 사용자가 직접가하여야 하는 불편함이 있고, 특히 컴퓨터가타워형 케이스같이 시스템을 책상아래에 놓고 사용하는 경우나 전원스위치가 시스템 측면에 부착되어 있는 경우에는 사용이 더욱 불편한 문제점이 있었다. 따라서 본 발명은 상기한 종래기술의 문제점을 개선코자 하여 윈도즈 '95 및 현재의 도스(DOS)또는 윈도즈상에 전원을 사용자의 키 조작에 의해 소프트웨어적으로 오프시키므로서, 물리적인 스위칭 동작에 의한 불편함을 제어하도록 한 것이다.The present invention relates to a power off device of a computer. In the conventional computer power-off device, it is inevitable to turn on the power supply to use the system. However, when the system is used for a long time, the user may feel fatigued. Inconvenient to be done, especially when the computer is used under the desk, such as a tower-type case or when the power switch is attached to the side of the system there was a problem more inconvenient. Accordingly, the present invention is to solve the problems of the prior art described above, and by turning off the power supply in Windows '95 and the current DOS or Windows by the user's key operation, the inconvenience caused by the physical switching operation To control the system.
