4-pin mini speaker of the motherboard

[Grindor]

Doing the troubleshooting of my PC, I discovered that the cause of the automatic switch ON of my PC without pressing the power button is the 4-pin mini speaker of the motherboard. When I remove the 4-pin mini speaker, everything is okay but when I install it again in my motheboard, the problem of automatic start is present again. I plan not to install the 4-pin mini speaker anymore in the motheboard to solve the problem. IS IT OK AND SAFE TO RUN THE PC WITHOUT THE 4 -PIN MINI SPEAKER ?????

It is perfectly safe to run without the speaker.

It is just to beep errors at you if something goes wrong.

I have never seen the speaker cause this issue(while 4 pins wide it should only have 2 wires).

Can you make 100% sure it is not connecting to something else other than its speaker connector.

Bottom line, You are safe without it.

Most motherboards and computer cases ship without PC speaker.

I started unplugging the PC speaker from my PCs something like 20 years ago until PC cases stopped shipping with PC speakers about 15 years ago.

It will not hurt anything aside from not being able to hear the beeps anymore.

Thanks mate for the answers, it almost consume me a day to discover the cause of the problem. I check the power button of the PC case and it's fine. I check the power switch connector in the motherboard and I thought at first that the power switch connector is the problem. But the 4-pin mini speaker of the motherboard is really the cause when I remove it and run the PC, everything goes smoothly. I don't know if the 4-pin mini speaker is broken but it beeps when I connect it to the motherboard.
