For some reason Ubuntu seems to think 55% is 'critically low' and shuts down the computer at that point. In the worst case scenario, it would be a hardware related problem (didn't have this issue in the past 2 years I've used this laptop though), but is there a way for me to find that out for sure, and if it is a software issue how would I fix it?
I can provide additionnal information if it is requested.
To change the percentage value for warning, type:
gsettings set org.gnome.settings-daemon.plugins.power percentage-low 30
Change 30 to your desired value.
To change the percentage value for critical warning, type:
gsettings set org.gnome.settings-daemon.plugins.power percentage-critical 20
Change 20 to your desired value.
Finally, to change the value for when your laptop shuts down, type:
gsettings set org.gnome.settings-daemon.plugins.power percentage-action 15
Change 15 to your desired value.
Comment if you are having trouble with anything.
To check if it's a software glitch or a hardware this applet might come in handy. It'll inform you about your battery's capacity.
