you dont have to "switch" it, just create the same account on the other computer. open your e-mail find the option to create an account. it will ask you for all the info. it would be helpful if you could open the current account on your pc and just transfer all the info as you see it over to the laptop. if you cant do that, you can simply call your isp and they will help you. just tell them you want to create a current account on a second computer.
