It does indeed, I just checked that this morning, and I also remembered
that I had snapped off the grounding prong on my wife's laptop power
adapter cord so it would fit into a European adapter on our last trip...
since the laptop power supply has no external metal components, I fail
to understand why they even used a three-prong plug in the first place
(there is nothing to connect the earth ground to).
