Does Norton 360 run scheduled tasks while the computer is in sleep mode?

I have Norton 360 scheduled to run several tasks once a week in the early morning. I put my computer in sleep mode when not in use so I'm wondering if these tasks will run while it's in sleep mode. Am I supposed to keep my computer on all night when the tasks are scheduled? I have Windows 7 64.
