Sometimes there is also an option to send ACPI "power button" event beforehand, but either way that's usually is the "last resort" case - last thing I want is a hardware shutdown just because of high load. Besides, it's none too flexible - sometimes just one of the conditioners goes down, so the room temp gets to, say, 25C, but that's still not a reason to panic if the situation is under control. And even when bunch of bioses shut system down all the systems correctly because of cpu/chipset heat when A/C dies, there'd be a lot of hard drive failures in a few weeks. -- Mike Kazantsev // fraggod.net
