Hibernation question

[Patrick Simonds]

I want to buy a UPS and leave my computer powered 24/7. I have a couple of
scheduled tasks I would like to have take place late at night. My question
is:

If I place my computer in hibernation when I am fished with my work (no
point in wasting electricity while I am not using it) will it wake up from
hibernation to perform the scheduled tasks?

No - but look here for a third party solution - www.lifsoft.com

No.

Also let me point out that an ordinay UPS is designed to keep your computer
running for a few minutes (depending on size, perhaps 15-30) minutes without
power. Its purpose is to permit you to do an orderly shutdown if the power
goes off, not to keep you running 24/7. There are UPSs that will keep you up
much longer, but they aren't in the ordinary inexpensive range of most
personal computer UPSs.

You can use standby mode, rather than hibernation. and check the "Wake the
computer to runs this task" on the Settings tab. But, scheduled tasks will
not run when the machine is hibernated, because when it is hibernated, the
machine is powered off. For a scheduled task to run, the machine must be
turned on at the time it is scheduled to run.

The answer is yes.
You can verify this pretty easily for yourself by scheduling a task,
making sure you check the box 'Wake the computer to run this task'
that's under the Settings tab under Properties of the scheduled task.
Then hibernate the computer.

Andy, I did as you suggested and you are correct. I scheduled an application
to start in five minutes from the current time and hibernated the machine.
Five minutes later the computer turned on, although the application I
scheduled didn't start. I verified the task command was proper by manually
starting the task and it started properly. The fact the task started at all
was a surprise. I would have lost a bet on that one. Curt
