I have an HP ProBook 455 G3 Notebook PC, and I just installed ubuntu 22 (it's the install disk that I have, and I haven't bothered updating it yet), and then upgraded to 24.04.
When I open settings, it shows that the battery is present, and at 76%, but not charging. If I unplug, it briefly reads "discharging" before showing me the rate of discharge. [enter image description here][1] [1]: https://i.sstatic.net/Wc5HuUwX.png

1747509041 17.878 discharging
This seems to make sense... the readout is 24.5/32 which is 76% charged, but it seems like at 76%, it should detect that it needs to charge, and not just sit at 76%?

I read another forum post that this was something to try, but it doesn't seem to work. I found a page on freedesktop upower devices that suggested a few other commands, but they don't seem to produce much different results. The information is likely out of date.
sudo systemctl restart upower.servic
This doesn't seem to do anything at all.
