Most laptop power supplies are "switching" power supplies. They can accomodate either current, all you need is the cord that goes from the transformer to the wall, or an adapter from teh plug on your cord to the wall.
I have a whole bunch of cords in stock here,
but since you said they have no standardized plug (weird for a communist country since they have standardized everything else huh?), then you're best going with a worldwide current adapter.
I would get a surge protector if I were you. Ideally one with a battery backup, even if it is small it will help condition the current so that it is uniform and consistant to your computer. Plus, most surge protectors come with a insurance policy if you laptop gets fried on their watch (check if that is good out of the country though.)http://www.killernotebooks.com/images/logos/mini_skull.gif
