Abstract

본 발명은 퍼스널 컴퓨터에 관한 것으로, 전원 입력상태, 전원 관리상태 및 하드디스크 드라이버 작동상태를 통합하여 표시함으로써 시스템 제작 비용을 감소시킴과 동시에 유해 전자기파를 감소시킴과 동시에 유해 전자기파를 감소시키도록 하는 퍼스널 컴퓨터의 작동상태 표시장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a personal computer, and more particularly, to a personal computer which can reduce system manufacturing cost by simultaneously displaying a power input state, a power management state, and a hard disk driver operation state, The present invention relates to a computer operating status indicator.

종래의 퍼스널 컴퓨터에서는 총 2개의 발광 다이오드를 이용하여 전원 입력상태 및 전원 관리상태와 하드디스크 드라이버 작동상태를 표시하고 있으므로, 다수의 발광 다이오드를 구비해야 되어 시스템 제작 비용이 증가되고, 다수의 발광 다이오드를 연결하기 위한 케이블의 갯수가 증가되어 유해 전자기파를 증가시키게 되는 문제점이 있었다.The conventional personal computer displays a power input state, a power management state, and a hard disk driver operation state using a total of two light emitting diodes, so that a plurality of light emitting diodes must be provided to increase system manufacturing cost, There is a problem that the number of cables for connecting the antenna increases and harmful electromagnetic waves are increased.

본 발명은 전원 입력상태, 전원 관리상태 및 하드디스크 드라이버 작동상태를 통합하여 1개의 발광 다이오드에 표시하므로 시스템 제작 비용을 감소시킴과 동시에 유해 전자기파를 감소시키게 된다.Since the present invention integrates the power input state, the power management state, and the hard disk driver operation state into one light emitting diode, it reduces system manufacturing cost and reduces harmful electromagnetic waves.
