If you enable the power management settings on a collection you have the ability to establish a wakeup time for that set of machines. So, if you want machines to wake up at 2:00am to see if there is any work to be done you can do that. Only downside is that ONLY applies to desktop computers. So, any laptops that are in that collection will not be woken up. The logic behind this is the laptop may be sitting in a backpack or something and we may not want it automatically woken up in the middle of the night and causing the laptop to overheat and catch fire! Perhaps some logic will be added later that says apply the wakeup time to the laptop but only if it's plugged into an AC outlet. But, that is not in the works as of this time.
