If you want you can setup automatic updates in kde settings. They will always stay out of your way and download in the background. They will install if you chose to click “update and shutdown” next time you shutdown or restart your computer.

A rasperry pi idles at about 2 watts vs a laptop that idles at about 4 watts. At $0.30/kwh (a very high price for electricity) you would save 5 dollars per year on electricity. This laptop trades blows with the rasperry pi and costs half the price (55$ aud vs over 200$ aud for a brand new pi 5) Even this second hand one costs 110$ aud which is twice the cost. With that cost of electricity it would take 11 years in order to break even. And that’s only if you consider monetary cost and not environmental cost.

This is generally not true. If you are using your laptop as a home server chances are it’s going to be idling 99% of the time and laptops are generally pretty good in terms of idle power draw if you manage to disable the screen (or just disconnect it, take it off and find a way to repurpose it)

And in terms of environmental impact saving a laptop from landfill is definitely better since the majority of a computers impact is from the co2 emmissions from the manufacturing process. And this isn’t taking into account the likely ethical considerations such as supporting terrible mining practices for resources like cobalt.
