I have an old ThinkPad 11e running Debian that I have repurposed into a home server. It's only supposed to run TVheadend. I don't need any other services for now, but later on i might add a few using docker.

Is it enough to set multiuser.target as default to disable gui and keep the system always on?

How can I disable all unnecessary services and minimize power usage?

Depends. Usually it is still good as a UPS for a few minutes, and some laptops have a bios option to limit full charge which lowers the risk even further.

And how much need is there for a UPS in this scenario - realistically.

Some of the people here take their admin-LARPing a tad too seriously. Most households have reliable enough electricity, and even if there's an outage once every quarter, would a dead battery even help?

I advocate for being realistic with one's own needs. Don't build a five-nines datacenter for a glorified weather station or VCR.

That is why I said it depends. There are many places where electricity cuts for a short duration are quite frequent. Often you don't even notice it, but a 24/7 server would be effected.

In general, I think the risk of laptop batteries catching fire is overstated especially if you limit the charge to 80% or so. So weighting these two issues against each other you can come out either way, but I think for most places it will come down towards a UPS being nice to have.

Worth taking a look at the battery - especially an old one on a repurposed device - before considering it safe. Spicy pillows happen.
