Few things. First, that's probably not a microphone but a webcam. Didn't
you know that you have one? ;)
Second thing, according to http://hughsient.livejournal.com/2007/05/24/ 
webcam can be used as ambient light sensor. It apparently works for you.
And third thing, run gconf-editor, navigate
to /apps/gnome-power-manager/ambient and uncheck "enable". Or you can
fiddle with values there.
