Either Linux has no idea what your battery is telling it; or your battery is just...toast.
Let's just hope for your sake it's just a funny linux bug. Replacing specific laptop batteries can be a tremendous pain if you can't find a specific cell that works for your device.
Nah, she's toast. Ran multiple distros, and the same problem persisted across Fedora, Arch, and Ubuntu. It's also an Intel machine, and I've been eyeing a Framework with AMD. Which is why I've stated I am not looking for tech support.
I must warn you of the dangers of pushing batteries in a failure state like this though; Lithium batteries can sometimes fail in explosive ways.
Keep an eye on the thermals and don't let it expand or pop on you.
no pain no gain
How is it that one cannot purchase a bunch of flat rectangular batteries and just put them inside the laptop (wherever they fit) and connect them manually to some custom charge controller? We do it all the time on other devices like drones and shit. We have generic round cylindrical batteries, why isn't there flat generic Li batteries?
You would be surprised how hard it can be sometimes to source batteries due to shipping rules and regulations; as well as the general difficulty surrounding just building your own battery pack...which can end badly if you aren't an electronic engineer or similar professional who knows exactly what they are doing.
I fear youโd had to reverse engineer some proprietary nonsense that some companies put in their battery in order to prevent free repaiโฆ rhmm, security of course, security..
I've not worked with batteries but I would assume there are two pins for voltage and ground, one temperature probe pin and or two pins for serial communication (probably IยฒC). If batteries would have had some sort complex handshake then it would have needed a corresponding UEFI patch so that system is able to refuse booting if the power level is too low. That's why I assume there would be no handshake (unless it's apple ofc).
Iโd say the motherboard firmware checks if the battery through those two extra pins you correctly assume to have (there are generally 5 pins). And if the battery is not original it refuses to charge the battery.
You can always boot using power adaptor even without batteries and even on apple laptops ๐
