about closing the lid on labtops

hello, i have a laptop that currently runs vista ultimate and i was just wondering how do i get my laptop to require a password everytime you close and open the lid while on the do nothing setting i have on my laptop. you see i want to close the lid on my laptop and still have it downloading updates and such and still require a password when i open the lid. the only way i can get my laptop to require a password in on sleep setiings and i cant figure out why. any suggestions would be appreciated. thanks
