Battery reported as nonexistant
Once again trying to figure out my old Dell Latitude C400, and it's annoying habits.
The battery, as far as Ubuntu is concerned, does not exist. None of the battery monitors can't see it, and I can't figure out why.
It's clearly plugged in, as without it, you can't even turn the laptop on, even on mains power.
But as far as I can tell... nothing else admits it exists.
So I have a laptop with an existential crisis over a battery...
Can anyone help please?
Thanks in advance.
