This question already has an answer here:
I'm currently looking for a possibility to stop my T480 from deep discharging my external battery, before switching to the internal battery. It should switch to the internal battery at a percentage of about below 7%.
Optionally this should be combined with an automatic hibernate as soon as the internal battery reaches a certain threshold.
So my questions are:
- Is there an existing solution to automatically switch batteries before deep discharging them, which also automatically hibernates if a certain threshold is reached.
- If there is not, is there a way to manually switch between batteries?
It is possible to write a custom script which checks every few seconds whether the batteries reached the thresholds to switch batteries/hibernate. But for this to work, I would still need a command to manually switch batteries.
