Toshiba Satellite M100 notebook microphone doesn't work

Hi,
I bought a microphone and headset and plugged in into my toshiba lap top but the microphone doesn't work, it doesn't pick up my voice or any noice. I have testing the headset on another laptop and it does work.

I was playing around with my computer and was looking at the driver and I think I might have accidently uninstalled the driver for the microphone now too... i disabled it now there is no option re re-enable it anywhere.
So it didn't work before when the driver was enabled now it definately doesn't work seeing as there is no driver at all.
I am running windows vista.

can anyone please help as I am currently travelling and was hopping to keep in touch with my family through skype.

Thanks

Could something be disabled in the BIOS?

sorry I am not very good with hardware... what is the BIOS?

It's too much for me to type here so I'll point you to a link.
http://en.wikipedia.org/wiki/BIOS

Among other things, there are settings in there that determine what's enabled and what's not. Read about it before you make changes.

I recommend you download the latest and correct drivers for your sound device first.

You can use a freeware program such as CPU-Z or Everest System Diag. to determine what sound card or onboard sound you have.

found here:

From there you can find out what drivers you need if any. And if you have the correct and up to date drivers and it still doesn't work, then I recommend checking the BIOS settings.

i have the same problem on the same type of laptop like Born. i have updated my driver. but my lappy still cannot capture any sound. can anyone advise on how to solve this problem using BIOS setup? thank u.

hi, i have solved the problem. On windows vista, go to Speakers Properties, and then to Levels tap. there u can see the setting for PC beep, microphone, line in etc..change accordingly. cheers!

hi, jai also the same problem. sil vous plait fazot explain me again how you could solve it: jai not understand your solution explained above.
thank you
