I'm a recent switcher, and in my windows laptop, whenever i just leave the computer on the screen will switch off but the computer doesn't go to sleep, it keeps running so i can download stuff or be still signed in to MSN. But with my new macbook whenever i leave it on for 20 mins or so, it just automatically sleeps, signs me out of MSN and stops charging my ipod. Is there anyway to make it so the mb won't go to sleep unless i make it to?
