Stop Windows Hibernation

[Nusse]

Environment: Running a Linux guest on a Windows host to do some long processing

Issue: Windows host goes to sleep thus stopping the processing my Linux guest is doing

Info:

As stated above, I am trying to find a way to stop Windows 7 from going in to sleep mode while Virtualbox is running. I know I can go in and disable it completely, but I don't want to do that if I don't have to. So is there a way in Virtualbox that I can go in and toggle some setting to block the machine from going to sleep until Virtualbox shuts down (My linux guest shutsdown the computer when it completes its processing)?

Thanks
