could be a power supply issue. any trouble when running on battery only?
i had a problem (no noise though) where the battery would not charge when connected to the adaptor. was a faulty audio controller, which is situated next to the power supply. try swapping out the adaptor if you have a friend with one and that will tell you if the problem in with the laptop, or the adaptor.
