Curious, are you able to take screenshot when this happens?
I’ll try and post it here although there isn’t much to see.
I get a battery critically low notification and something like 10 seconds later the laptop shuts down.
I am running Fedora’s cinnamon spin so it may be a Cinnamon bug ? It wouldn’t be the first bug I get
Edit: @Loell_Framework So yeah it happens too fast for me to screenshot it. Another piece of information is that I am maxing out my battery at 60% in the UEFI since it’s stationary.
Edit 2: Actually there’s a Cinnamon setting to “Do nothing” when the battery is extremely low (which I never let happen anyways). So I guess I jsut “fixed” my issue
