Hello,
My Vaio Pro 13 has been making really strange annoying buzzing noises. I've tried some of the suggestions above and they didn't work. At first I thought it was a fan issue, so I had that replaced, but still the buzzing sound has been persisting. What makes matters kind of strange is that the sound is only prominent when the laptop is placed on flat surface. If i'm lying in bed and have it propped against my legs on an angle, there's no buzzing sound. Please help.
Thank you.
