    Hey Battery, are you OK? You've been saying 0% for 15 min now. (lemmy.world)

    Running a Gigabyte U4UD, been having battery problems for months now, and the battery health only reports 50% capacity. Started playing Battlefront and got distracted and saw my battery looks like this now. Been doing this for 15 min, so either my battery is magical... or the Clevo design is flawed. Seeing how long she goes for on battery before it just dies.

    I am not looking for tech support, just thought this would be funny.

    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 you‘d had to reverse engineer some proprietary nonsense that some companies put in their battery in order to prevent free repai… 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 I²C). 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).

    I’d 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 😇
