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? :) > Cheers > -- Regards, Bengt Richter
