Not sure, but being an American living in Ireland, I can tell you that although there is a switch on the computer to change the power supplied the actual plug is TOTALLY different. I couldn't just plug a US TV into an outlet over here without an adapter and from what my friends over here say, the plugs are once again different in France...they are thinking it is a two prong circular outlet. Now one could use an adapter, but they are crap and most ppl would only use them for travel purposes and not long term electrical supply for something like a computer or tv.
