strange sound in asus g73jh-a1

[wteo40]

I POSSESS a ASUS G73JH-A1 and I am having problems with a strange sound when it close the screen of notebook, to a time atraz I removed the inferior cover of notebook and used a compressed air to remove a little of the dust since then I started there with this problem, and when I touch in the lateral of the screen is as if it was touching in metal, this problem only appears when I use high the falantes to distribute the sound and with earphones this does not happen would like to open notebook to see what it occurs but would like an orientation for where to verify, already carried through this opening for exchange of thermal folder of the video plate. aid for a Brazilian who does not have as many resources as in its country and that paid very expensive for technology with difficulty, being thus necessary mante it.

Could you PLEASE rewrite your probelem again? I know english isnt your first language but please try to clean it up.
Dont use complex vocabulary because i dont think you use it grammatically correctly.

Thanks!

I think you should try muting your mic input. It can cause a squeal when closing the lid.

Your microphone definitely needs to be muted in the sound settings. It's simply a coincidence that it happened around the time you used the air duster.

I did not find the place where I can make this desabilitaçao where would be? I use windows 7 ultimate, and would have that to change the microphone to solve the problem total?

Right click on the Windows Speaker taskbar icon, and select Recording Devices...Microphone.....Properties.....Levels... and hit the Speaker button on the tab to mute it.

You should also be able to mute it from the Realtek Audio app (the orange speaker) and mute the mic in the recording options.

sounds like the mic is picking up the fan noise and amplifying it.

Ya it's feed back because the mic come closer to the speaker. muting the mic will fix it.

I would like to deligar the mic of the plate mother to have certainty that is it therefore already disactivated in windows and continues problem the same is distrustful of high the falantes, still I have I doubt where I am the connector of the microphone in the plate mother
