Automatically turn on PC when power is back?

It would seem that in reference to post #9 from the OP, running the script manually would not necessarily be a problem as long the OP could turn on the PC from an exterior location remotely.

Hmm, I would like it to be automated though, because even if I login to my router remotely, I have no way of finding out whether the power is back (because the router is backed up by a much larger battery and never loses power).

That power circuit suggested by jaclaz does sound workable, but I worry about power surges which might kill the PC (common in my area), and also because it does bring in a few complications of its own as mentioned by others above. So I'm back to the table again!

The suggestion was about the most basic something you could do.

Nothing prohibits you from using optocouplers or opto-isolators:

As well, nothing prevents you to operate through a self-powered device using a power adapter converter from mains (not connected to the UPS).

And again, nothing prevents you from controlling a simple "robotic arm" that simply pushes the power button, a LEGO one would do, if they make a cd-changer, you should be able to make a lousy button-pusher ;):

You could query your UPS for that.

the Back-UPS UPS would have to be connected to the device your attempting to query from or it couldn't shut down the PC. I don't think it would work through a USB splitter, although it would be interesting to see

This might not be of ANY use for you, but since I stumbled upon it by chance, I am posting it so that it may be of use to aome other members with similar (but not SAME) problem:

Poweroff is a small program that allows you to control the power state of your pc.

It can power off, shutdown or reboot your pc, log you off, lock your workstation, go to standby or hibernation mode and even wake up another pc.

All actions can be done locally or on a remote pc (if they are running poweroff).

The action can be performed immediately or scheduled, by using a built-in scheduler.

All actions and options can be controlled by command line options. This way, you can easily integrate poweroff in your batch files.

It should run on Windows 95/98/Me/NT4.0/2000/XP, each with its own limitations. Beware that I haven’t tested the program on these operating systems, but in theory it should work on all of them…

Another huge BUMP :w00t:, but related :yes:, extremely simple and possibly useful (even if not specifically in this situation) in other similar situations:
