When my laptop battery is full and the charger cable is plugged in, my microphone makes a weird buzzing noise. I recorded this and slowed it down and altered the pitch a little bit and here you go.
Comment if you use it.

  I have the same problem with my laptopn (a Toshiba Satelite Pro). Although the sound is very different. On mine it is just a simple buzz.
