Also tried to tackle the problem with power not coming back on its own.
The problem appears when the computers shut off but a little bit of
power remains in the UPS batteries. The computers have a BIOS setting to
boot as soon as power is connected - but if the UPS is not drained, the
power is never really cut, so the result is that they don't boot if the
power comes back.
nut handles this for most UPS'. There are some models that don't support
the proper command, but you can check for those before buying one.
It does this by having the UPS cut power to the load even though there
is still battery power. The command is issued with a time delay that is
supposed to give enough time for shutdown to complete after the command
is issued.
Oooh, sounds like a very good feature! How do I check if a UPS has it?
