Find a laptop with thunderbolt and stuff an HDX card in it and add some Digilink-compatible interface. Or, if you are mixing but not tracking, UA makes some powered external boxes(see their site for connections). Personally, if your laptop is running out of power, a better laptop is probably the wisest(and cheapest) first move. And, do you REALLY need a laptop(you can get a lot more horsepower for less money with a desktop)?
