A scheduled task may not run after it wakes a Windows Vista-based or a Windows Server 2008-based computer from hibernation
Consider the following scenario:
- You are running Windows Vista or Windows Server 2008 on a computer.
- You create a scheduled task to run at a given time.
- You configure the scheduled task to wake the computer to run.
- You put the computer in hibernation (S4).
In this scenario, the computer comes out of hibernation at the expected time. However, the scheduled task may not run as expected.
