    So it seems whenever my recording laptop is charging, it would cause
    my studio monitors to make electronic squealing noises.
    Does anyone know any solutions around this?
    There is not much battery life in laptops.... :?

    To gain the most of a laptop battery you have to turn down the screen brightness. The bigger the screen the more it's a battery whore. Also, look into auxiliary batteries. Some fit into optical bays and some universal batteries plug right into the power adapter port.

    I mentioned this is the other thread that jg49 linked to, and that is to get hold of a 12V car adaptor for your laptop. Run it from one of those portable car batteries with cigar lighter outputs for the duration of the session. No mains connection = no hum.

    Of course if the squealing is due to the power circuit in the laptop itself, you may not see a huge difference, but at least you will not be injecting large current spikes into the ground circuit.
