I began selling computers for Compaq in 1997. The term "power adapter" does not IMPLY anything. It is the common technical name for the AC power supply (and appropriate cord/plug) for any given piece of computing equipment.

The term "power supply" is insufficient because it does not specify the type cord cord/plug (which in many cases is of proprietary design, particularly with regard to the connector on the device itself.)

In this case, the standard plug that ships is a two-prong ( non-polarized NEMA 1-15P.)

Again, there is NO difference in noise through the jack when the computer is plugged in or running solely off it's battery.

I hope this clarifies things.
