    Hi guys!

    First thank you for this forum, it helped me several times with minor problems. Now I have a bigger one:

    The microphones in the lid are very sensitive. I don't know why, I didn't do anything abnormal with it.

    Here's the problem:
    uk.youtube.com/watch?v=mNjf-I7k_No (sorry I am not allowed to post url)
    What I noticed is that (provided the volume is turned on at maximum and the power supply is unplugged) if I lean the machine on its back, the same microphony sound comes up that I first heard in the kitchen and thought it was because of the microwave. When I first heard it, I was putting the laptop on the table, so the laptop was in the same position as here described.
    Note: This happens only when power supply is unplugged and the volume is turned on at max

    Here's another video:

    Second, if I slightly stroke the lid with the tips of my fingers, I can hear that sound coming out of the speakers!!! This happens when the volume is loud (not necessary max) and no matter if power supply plugged or not.

    I believe the problem is in the microphones, they somehow mix with the speakers.

    Anybody had this problem before?

    Thank you.
