Yup.  I have this problem with my Dell Inspiron laptop, which I tooled
around with as a sampler, and with Live, for a while.  Had to either run on
batteries (no good), or use a ground lifting plug on the power cable to get
the 60 cycle hum to go away.

By the way - this is a known problem with Dell laptops.  Dell support folks
don't like to admit it tho.
