Windows 7: Microphone jack connector not working

Microphone jack connector not working

Hi

This is a HP 6720s notebook and it seems the microphone connector plug might be broken.


I tested the microphone on 2 different computers and it's working fine on those.


The headphone connector (which is next to the microphone connector on this notebook), is working all OK so I don't think it's just a driver problem.


This computer was disassembled (then reassembled) by a computer technician for internal cleaning, maybe he forgot to reconnect it or something... I'm not sure. (I'm mainly into desktop computers but I'm not afraid to take a look inside to see if I can fix it )


So my question is, what can be the problem? I'm only guessing. We could also try software tricks as I don't think this technician would have messed it up on purpose but who knows, maybe he just forgot about that connector.


So... where should we begin diagnosing this problem?

Any help is appreciated.

Just a shot in the dark here......... have you been to device manager to check for missing/outdated drivers?

Conversely have you tried a system restore to a point before the cleaning? Assuming it worked before that.

In that situation you take it to the tech and tell them the jack that worked before they cleaned it now doesn't work.

Should be free....

If your car....

Sure, I checked that. No missing/outdated drivers, also installed a fresh sound driver offered by Windows Update, no difference.


I did a full reinstall a few months after the cleaning.


I used Skype for microphone setting (Skype is configured correctly), I called the echo test.

I was surprised because it wasn't completely silent, there were some random noises, but I couldn't control it, it wasn't actually coming from the microphone.



The microphone is working great on 2 other computers, I really think this connector is broken.

Sounds like a good idea!

Edit: the problem is that this repair has been done years ago, and the tech guy probably doesn't even remember this computer so I don't think I can blame it on him.

Hmm. I'm starting to think this *could* be a software issue too.
Also the signal bar sometimes moves.

I'll try different drivers.
