Typically that BIOS setting (as opposed to always on with power) will
only start up the machine had been operating right at the point of the
power interruption.

In this case, apcupsd cleanly shut down the machine prior to power
being removed, so from the BIOS perspective "last state" was "off",
and that's how it stayed when power was restored.

You'd need to configure BIOS so that the PC always powers up as soon
as it receives power (regardless of its prior state) to restart in
this scenario.
