MacBook Pro and Buzzing

[falcon2000]

Hi all

I have MacBook Pro and the power adapter has 3 plug like this.

But it was not earthing during charging and I could feel buzzing sensation as you touch the metal of MacBook Pro.

People said it could fix it by using power adapter extension cable. Appe store in here sold version has 3 plug.

I heard some peoples experienced the buzzing caused they have use power adapter has 2 plug but fix it by used extension cable has 3 plug.

My power adapter already has 3 plug but still buzzing. Would the extension cable fix it ?

Thank

Even with the grounding extension cable there's still the tinkling, only lesser than compared to using the non grounded duck head. To totally avoid this, get a plastic external case and a protector below the keyboard where you'd rest your palm
