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?
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.
