[G4] G4 Speaker is buzzing

[Ron]

It's not buzzing, it's snoring!

> The  internal 
> speaker makes a buzzing sound, which sounds kind of like a digital
> alarm clock, or a small motor running. This does not happen all the
> time but it only happens when the computer is in sleep mode, as soon as
> it wakes up the noise is gone. Usually leaving the computer sleep
> overnight results with the buzzing in the morning. Again it does not
> happen every day. For example monday morning the computer was buzzing
> and today also, but tuesday there was no buzzing. This buzzing has been
> happening for the last couple of months. It seems harmless but, I am
> not sure. Mabey it is the battery going dead.
