    The long extension cord has 3 pins and grounds your Macbook, which can cause ground loop interference (noise).




    Whereas the small plug has only 2 conducting pins and effectively ground lifts the laptop, preventing it from causing a ground loop.

    What about the charger? Was it the plug, or a bad charger?

    If the 3 pin extension was causing the problem, you can use a standard figure-of-8 lead instead which is 2-pin like the small plug.

    Ground lifting your laptop is a somewhat better solution than using a ground loop isolator, which attenuates low frequencies.
