Yea i want to buy this latp from america and i am worried about the ac adapter and i am insire whether it will work in an australian ac outlet. If it doesnt where what should i do to make it work in an aussie power outlet? Is there a store where i can buy some sort of adapter converter?

Universal Power Adapters are quite common. Many are specific to the device manufacturer.

What is the make of this laptop? Their web site under accessories would be the first place to look.
