Looking at my mandriva2006 machine, when I hit the power button, nothing happens. It seems to have an entry in my dmesg output, but when I try to look at /proc/acpi/event, it says device busy, so I can't actually tell what is going on.

ACPI is a tricky thing, so I was wondering if someone can steer me in the right direction on where I should be probing. This is a full standing arcade machine, so I would like to make the power button shut down, otherwise I will have to make a kludge to get it to shut off, which I would prefer not to

Thanks in advance,
Kris

Recent computer or older? It could be one of those mythical real hardware power buttons.
