When I opened the Dell optiflex gx280 to re-wire power button so that i can turn on the cabinet from outside, i realized that dell pc's power button is wired in not so simple way. Instead of simple two wire going to the switch, actual switch was soldered on small pcb and the pcb is connected to the motherboard with something like IDE cable. then i found this youtube video.
i cut the wire harness and connected an arcade switch to the 2 wires from the cable harness, it worked fine.(you can connect any 2 wires to the microswitch's ground and NO(normally open) lead. doesn't matter which one goes to which.)
와이어 번들을 중간에서 잘라내서 위 비디오에서 가르쳐주는 두 개의 와이어를 연장시킨 후 캐비넷에 사용할 파워버튼의 두 단자(normarly open단자와 ground단자)에 연결해 주면 됩니다. 두 선이 뒤바뀌어도 상관 없습니다.)
thank you youtube and video uploader.
