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.
The nice thing about some battery backup is not keeping it running during an outage, but safely shutting it all down.
I agree on the laptop battery, I’m just disagreeing on battery backup. It serves a purpose, as does decent surge elimination.
But not for us.
That’s what I meant by larping. The vast vast majority of us here would probably not even notice if their systems went down for an hour. Yes, battery backup has its purpose. In a datacenter.
I mean, what’s on the line here in the worst case? 15min without jellyfin and home assistant? Does that warrant taking risks with old batteries or investing in new ones?
That equation might change if you’re in a place with truly unreliable electricity, but I guess those places have solutions in place already.

US defaultism in action, it seems.
US power sucks plenty!
Texas is an extreme example, but outages happen everywhere. It was only a bit over 10 years ago when Sandy basically hit half the US and took power out in the tristate area for weeks. With climate change making things worse…
But even when things are running well, not including the random downed line or busted transformers, its still better to give your hardware clean power and avoid the small spikes.
The US default, that I never left Europe. What an achievement for the USA!
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.
Everything has pros and cons. I’ve seen 3 laptops (of my family) with batteries that looked like a baloon after several years. I’ve subsequently removed or replaced them. I’d definitely check on them every now and then. A UPS is nice. Burning down a house isn’t. I haven’t seen them catch on fire (yet), they supposedly have at least some protection. But definitely get them out of the laptop once they’re dead anyways or don’t look alright. Everyone is responsible to make that decision on their own. Take care.
