Never did find a more elegant solution. My problem has always been the opposite, when the battery gets low enough, can I effect a clean shutdown before the UPS runs out of power. B^) apcupsd allows you to configure when you want the shutdown to start either as a percentage of battery life remaining, or at a fixed time before the batteries dies. Knowing whether either of these is an accurate amount is the problem. I keep adjusting my values, but full power outages which drain the UPS are so rare for me that when it happens, its too late. (OTOH, I get lots of power fluctuation which the UPS treats as power loss/power restore, usually within 4-5 seconds, but are actually just short voltage drops (brownouts)). > In any case this may not be the UPS for you but this works well for me. > Someone can almsost always get to the server if the "Power restored" > page doesn't come in within 2 hours of power out... -- Kevin J.
