One question which you may have already answered: what if the UPS battery gets to 20% and upsmon signals a shutdown - how does the netbook know how to turn back on later? If the netbook doesn't have a way to boot back up automatically when the power comes back, you might be able to find a cheap SBC or WiFi router with a USB port, that can run NUT and act as the master.

I think you want upsmon to trigger upssched for the "off after 5 minutes" requirement. I don't use upssched myself; hopefully someone else can offer help if needed. If nothing else, we do have source code :-) The soft shutdown/WOL part seems possible. -- Charles Lepple clepple@gmail
