Weird sound from power supply

Biztro · 2012-04-30 23:12:05

I am a new arch user from windows 7.

When I first installed windows 7 on my new computer I experienced weird noise from my power supply. Crackling/sparkling/coil whine type of noise which increased during rapid movements of windows or viewing videos. I fixed this by disabled speedstep and c1e in bios and by enabling eco power mode in windows 7.

Now when I got arch installed my problem has returned even thought bios setting are the same. So my question is are there any similar way to put my power management so 'eco mode' in arch as well? Here is the option in windows 7 https://www.youtube.com/watch?v=SIwXCotzrE0

I'd replace that power supply before it burns down your residence.

Same thing happened w/ one of mine. Buzzing sound when under load. It would also get hot to the touch. I replaced it as should you.

I did replace it with a new one and same noise. So nothing wrong with the supply. Its the power settings.

Something is wrong with your hardware. It just hasn't been identified yet. Your hardware should not be making "weird noises" at all.

Well, it didnt make any noise in windows after the changes i described in first post.

It must be Linux then. (Or perhaps tunnel vision) Have you considered that it might not be the power supply, or is that a fait accompli ?

Hint: does your system have a microphone? Speakers? Have you unplugged them?

Your CPU is throwing out electrical interference, when changing its power-saving settings. Which is probably picked up by the speakers, which can make a slight noise even when apparently switched off. This seems sadly common in laptops, where all the components are squeezed in next to each other.

Google for how to do the same in Linux.
