    Annoying buzz coming from power block
    The power block that connects to the extension cord or plugs into the wall emits a buzzing sound when I'm using my laptop while it's plugged in. It's louder at certain times, like when I'm processing something or scrolling a webpage.

    Is this normal? It's not so loud as to be distracting, but noticeable.

    Is it new? I'd get a replacement if so. Buzzy power supplies are usually on the way out.

    I judge you when you use poor grammar.

    i agree. Mine most certainly doesn't buzz. Perhaps that one is defective?

    If I put my ear up to mine, then yes I hear a buzz. Through normal activity, I do not.

    i got an electric shock from mine lol (i did pull it out without turning it off so its my fault not an issue with the powerblock itself) just a warning. Turn it off before unplugging it!
