Sometimes there is also an option to send ACPI "power button" event |
20 |
beforehand, but either way that's usually is the "last resort" case - |
21 |
last thing I want is a hardware shutdown just because of high load. |

Besides, it's none too flexible - sometimes just one of the |
24 |
conditioners goes down, so the room temp gets to, say, 25C, but that's |
25 |
still not a reason to panic if the situation is under control. |

|
27 |
And even when bunch of bioses shut system down all the systems |
28 |
correctly because of cpu/chipset heat when A/C dies, there'd be a lot of |
29 |
hard drive failures in a few weeks. |
