Squeak after lid close

Question

I have a strange problem with Ubuntu 10.10 - when I close the laptop lid (Samsung r580) it makes a very high squeak. This doesn't occur on Win7. I am currently using 2.6.35.27 kernel. If you need some more info to help me with this problem just ask. Thanks in advance.

Ok, now I can confirm that recent power-managment update fixed the problem.... finaly... after about 3 months I can close the lid without being annoyed by that sound :) Thx everyone for helping!

Apparently it would be something like this: If the microphone feedback (input level) is set too high this can occur because of the magnets on the lid...

Not sure if it's the same problem as yours though, but seems to fit the description.

See if there is a BIOS option to turn off signals related to power management.

Are you sure this isn't the beep from the suspend action? Suspend in another way, if it happens as well. That is your answer.

Could also be the soundcard giving a death rattle as you cruely cut off its power. Use headphones to silence the speakers before closing the lid, see if that shows you the cause.
