Not all UPSs have functionality to cycle the power outputs when the power returns. And some that do require a specific command to be sent to it to enable this, which might need some closed-source client that only works on MS Windows. A few years ago there was a message on the nut website asking for a boycot of APC because they changed the protocol and refuse to provide info on it, forcing people to use the APC bloatware.

However, in the even that power is restored between the UPS kill and the time it actually turns off the mains will still not be cycled. But theoretically this window should be pretty small. Dan it does seem as though this hits the issue - that when power fails, the ups triggers a shutdown, but the power doesn't fail hard enough to wind down the ups too, in which case the machine that is waiting for the offbattery event is fast asleep and misses the message. it's a shame the killpower command does nothing for you. the only way forward that i see would be to get a small device a la raspberry pi, and have that run apcupsd on it. you can then have that device run wake on lan if it detects the power is good, and trigger remote shutdown when not.

So the BIOS has no real way of knowing that it should reboot again in that case. Have you looked for any BIOS options related to powering on from a USB device? eg, I'm thinking of PCs which can be switched on by pressing a key on the keyboard... could that mechanism be triggered by a UPS? Or perhaps via wake-on-lan? (Note I have no real experience with UPSs, I'm just trying to think of other ways that PCs can be made to power on). Bruce -- :b

Regardless if the mains power returns soon after the UPS has initiated a shutdown to the PC, shouldn't the UPS recycle the power anyway, so that the PC comes back on as set in BIOS? I assume that your PC shuts off thus reducing the load - and, of course, this increases the runtime of the remaining battery so the UPS never actually shuts down? I don't think you can get apcupsd in any case to cycle the outlet groups, but you can try a couple things. First, is apcupsd even sending the signal to shutdown the UPS? /etc/init.d/apcupsd.powerfail needs to be added to the shutdown runlevel: `rc-update add apcupsd.powerfail shutdown` I have even tried to run the command /sbin/apcupsd --killpower from a root terminal (while in default runlevel, after manually creating the file /etc/apcupsd/powerfail) and nothing happened. At the end of the shutdown this is run and it tells the UPS to power off. If you have multiple PCs this should be enabled on the slowest to shutdown to make sure it doesn't kill a machine still shutting down. Am I missing something in the configuration or the daemons that should be running?

That was a musing, it wasn't based on testing. On most UPS systems I've seen when the power comes back the UPS resets. As I said, you can time your shutdown and set KILLDELAY, but make sure you add some extra time in case the shutdown takes longer than expected. `man apcupsd.conf` only has a two-sentence description for killdelay usage.

You can try sys-power/nut, and use something like: sudo /opt/local/bin/usbhid-ups -a apcups -DD to get some debug info from your UPS, after you set up the configuration files. You could either try the apcupsd-ups driver which acts as an apcupsd client, or you give usbhid-ups a spin as I show above.
