Sometimes (particuarly if you are using apmd -z) the default polling interval
of 10 minutes is a bit lazy and we fail to respond to low battery situations
before they become no battery situations.
Perhaps something smarter could be done, but the simplest change is to reduce
the default polling interval to one minute. This is still rather slow, so as
to not introduce unnecessary load on the system, but should make it more
responsive to changing conditions.
