I'm experiencing quite a big issue in lubuntu.
I have an Asus UX31 series with more or less 4 hours battery life.
My problem is that it badly dies with 30/35% of battery remaining. Just like that. Even Chrome doesn't remember its state (open tabs) or sometimes my zsh history is also corrupted.
My xfce-power-management-4 config should be alright:
- critical battery rate should hibernate
- critical battery rate is at 10% but it seems never to be reached (so I don't think it's a matter of signal sent too late as I've read in some other posts)
- hibernation works very well when triggered manually or when the laptop is plugged in
It seems like at some point, the battery acts as if disconnected from the laptop, but I think (and hope) it is a software issue since it always happens at around the same moment in the battery life.
Any idea where should I search to solve this issue?
