      I typically don't use a laptop but I've read that gnome-power-manager's estimate is done on time remaining, rather than percentage for battery charge. I just installed Fedora 31 for a gift I'm giving my stepsister and it can't detect the charge. I've read that there have been workarounds for other distros but I haven't seen anything for Fedora. Are there any workarounds you guys are aware of?

        In the BIOS settings, is there an option called Battery Remaining Time and is it enabled?

          Doesn't exist on this particular laptop

            I pulled the battery out when I was testing and it did not fix the issue. Also ran HP Diagnostics and it came back with nothing. My boss had a new battery for this model and when I installed it, it fixed the issue. Unsure what the issue with the battery was.

              Modern laptop batteries are anything but dumb devices. Most of them got an SMBus interface, a bus derived from (and very similar to) I²C.

              My guess is that either the firmware on this specific battery is bad, your host driver doesn't like the battery or you just had some dirty contacts and the host just couldn't talk to the battery.
