I've been having some trouble with a faulty UPS lately, seems to be too slow at switching from AC to battery power, which causes an interruption in power supply to the computer. The UPS is going to the service next week but what I want to figure out in the meantime is why it is that every time there is a power interruption, the computer restarts itself? I have checked all power settings and it isn't ticked anywhere that it should restart after power failure: I even turned off all automatic shutdown options for the UPS... but it made no difference. It also made no difference when I disconnected the UPS USB connection to the computer. So I don't think it's a software/model/compatibility problem. Any idea where else to look, any other way to stop it from restarting? Oh and, I'm on Snow Leopard, Mac Pro 1,1.
