My notebook's power supply adapter went bust in 2019, but thankfully, the 
circuitry inside the notebook is fine, only the external adapter had broken 
down. So I replaced it with a cheap universal one, which fixed the problem.

The notebook has 4 GiB RAM. (That was the maximum available. I picked it 
because I wanted the notebook to last.) Fedora 35 with KDE Plasma runs fine 
on it. Not fast, but usable. But it is not my primary computer, my primary 
computer is the desktop on which I am typing this: Sandy Bridge Core 
i7-2600K (released 2011, supports up to AVX(1)), 16 GiB RAM. That said, the 
2008 Core 2 Duo notebook goes with me when I travel and/or give 
presentations, and still serves me well for those purposes. And it has more 
RAM than my third GNU/Linux machine, a PinePhone with 3 GiB RAM (edition 
"with convergence package") – but that one is of course ARM aarch64, not 
x86, so it is not affected by this thread at all.
