Thanks for the reply.

I thought the LCD whine was related to graphic card driver on Vista since it was quiet on Mac Os. I did some search on google and the only solution is to uninstall graphic card driver and reinstall an old version. Unfortunately it was only for XP users
I am really aware about the "using battery only"noise and will definitely contact Apple store.
