What would you advise if there's no battery power,
or for some reason one is running on plug power only,
for worriers that the bulding power might fail?
I'd guess a power brick would power for some milliseconds
and wonder if this is detectable, i.e., to do something
at least to leave a goodbye world message somewhere if the machine
was not suspended with sufficient state to resume after power restore?
Buy a UPS, and don't go away long enough for that to run out? :)
