Stepping Adapter

What voltage converter and / or AC adapter should I buy to use a laptop / hairdryer in South Korea?

I moved South Korea in a few weeks and I use my laptop and a hairdryer in the U.S.. What kind of voltage converter do I need? Be I need a converter to resign, but I'm not sure where to find the best price, and I am confused about the amount of energy I need for a laptop and / or dry hair. Thanks for your help!

Telovelace is right on the computer, but the difference there is a change of food, usually visible from the outside power switch for different voltages. You can say 155 and 230 though. It depends on the manuf. If you can not see the computer case open and see the food, it should be there. If not, you can get a power supply voltage is again ATX double for as little as $ 25. I would like for the team. I do not trust converters electronics, but are fine for the dryer. Also my wife has a hair dryer switch 220 in this.
