Here is a thread where we plowed much of the same ground discussed in the current thread, but also dug into the guts of the system in question (not a laptop with external power supply, but a desktop with the same noise issue) to try to better understand the source of the problem.

For reasons that are not totally clear to me, plugging the PC into the power outlet through an Ebtech Hum X Voltage Hum Filter (which appears to filter out ANY signal on the ground line)solved the problem. Indeed, the system had even less electrical noise than when a ground lift was used, and it is a totally safe solution.
