Hi Binoculars,
It should simply require the purchase of a simple travel adaptor. Most computer power supplies are auto sensing switch mode power supplies, which will work on 100 - 250V AC at 50 / 60Hz.
The lead and connecter between the power supply and the laptop does indeed change according to model.
So no probs.
Check on the power supply to make sure its 100 - 250V or thereabouts, but it should be.
Cheers,
