This Can (sort of) Be Done
Authored by: Makosuke on Oct 12, '05 03:30:18PM

This actually can be done, as such:

The "Restart after power failure" option will reboot the computer any time AC power goes away then returns... INCLUDING when the computer is off. That is, if you turn that option on, shut down your computer, then pull the plug and put it back, it'll start up again without pushing the button.

And, since some UPS software (sadly not OSX's built-in feature) allows you to power down the UPS after X minutes (one assumes after the computer has had sufficient time to shut down), which in turn cuts AC to the computer, once the utility is restored and the UPS turns itself back on, the computer would also restart automatically.

Again, this would require a UPS that can turn itself both off and on based on a timer and utility back up, respectively, as well as Mac-compatible software that is compatible with it, but if you can find both of those things (which should be possible--I'm pretty sure APC UPSes and their software offer these features, for example--then you can have your computer come back up automatically after a power failure.

The only time it wouldn't work would be if the power came back on after the computer had begun to shut down but before the UPS had turned itself off...

Or, just leave something with reasonable amount of power consumption on the UPS port...

The computer shuts down, but the remaining attached device still draws power, eventually killing the UPS. As long as power doesn't come back on in the intervening time, this should get around the timer. Of course, if the unit had a timer, and the power came on in between it would STILL have the same issue.
