I am thinking of buying a laptop in the U.S.A. and as you know it is only 110v over here, what do I need to convert it into 240v do I need a transformer or a new powerpack or do I need anything else ????\
You will just need to buy a new lead from the mains to the powerpack. Depending on the make, this could be a kettle lead, a figure of 8 lead like the ones used on radios, or a bespoke lead like Dell use. (a new lead will be much better than carting a plug converter around with you)
Regardless of power, check the keyboard. The £ sign will be missing, and in it's place will be the # sign.
