Windows 7 Task Scheduler sleep command.
Well, I figured it out. To put a Windows 7 computer to sleep at a specified time using the Task Scheduler is a two step process.
First, you must disable the hibernation function. This can be accomplished with Admin rights on the CMD screen. See tutorial below: Hibernate - Enable or Disable
Second, you need to use the following command in the Windows Task Scheduler:
Rundll32.exe Powrprof.dll,SetSuspendState Sleep
That is it!
