Thank you for fixing that Yar! I don't think we need to spend any money to buy a UPS, we have plenty laying around and it's just a matter of connecting one to the appropriate hardware and connecting the battery of our choice to it, and then configuring apcupsd the expensive thing about UPSs is that the battery they come with is tiny and not cheap, but if one is willing to mount the battery outside of the UPS battery compartment, it's trivial to find a 12V battery laying around. first step will be to locate a UPS in the piles that has a USB port, so that it can notify the computer when main power has failed, so that it can do a graceful shutdown. -jake On Fri, 26 Oct 2018, Yardena Cohen wrote:
