How do I make my laptop sleep when it reaches some low battery threshold?
I’m using Ubuntu, but I have i3 as my window manager instead of a desktop environment.

How to make sure that Thinkpad discharges external slice battery first?
The thing is that when an external slice battery pack is connected, the laptop first discharges the internal one. This is a problem because then it is impossible to switch between multiple external battery packs without powering off the laptop. It is also not possible to just disconnect the external battery pack when you e.g. need to insert it into a docking station.
