Debian operating system
Debian is a free operating system (OS) for your computer. An operating system is the set of basic programs and utilities that make your computer run. Debian provides more than a pure OS: it comes with over 59000 packages, precompiled software bundled up in a nice format for easy installation on your machine.
Sounds quite complicated issues. Did you try with any other distro?
Your battery removal doesn't cause any of your problems. I've used multiple laptops without batteries long-term (even for years) with zero issues.
If any other distro doesn't resolve your problems, I suspect your motherboard is either corroded or has broken components on it.
Corroded... that's something I hadn't considered...
This is my "outside" laptop... been using it in places I wouldn't want to risk a more expensive machine... ๐ค think I'll disassemble it and check for corrosion...
Could be something in the process of breaking... could explain the erratic behaviors, I guess?
I haven't tried any other distro yet. I've been with Debian my whole Linux life. But I might try XFCE again... that was my preferred desktop for years, only the new update triggered me to try Gnome properly.
