    my laptop charger makes a pitch sound .
    this sound happen just when I have my laptop turn on and charging the battery .

    the noise disappear as soon as :

    1-the battery fully charged
    OR
    2-the laptop in sleep mode or turned off

    is this normal ?? or there is something to worry about ?
