My experience with using an UPS is that they have caised an outage every few years, which is more often than we get power outages where I live, so I didn’t replace the batteries last time the UPS took down my server, and are just running straight from the wall. It might be better with a more expensive UPS, but it’s not worth it for me.

Don’t know about the admin page, however, the client on my tv does that if I watch half of it and continue watching at a later time.

I’m using FancyWM on my Windows 11 work pc. It works quite well for me.
