My Lenovo T460s has two batteries. When one of them is empty the laptop does an emergency shutdown which basically makes the 2nd battery obsolete.

I already set org.gnome.settings-daemon.plugins.power use-time-for-policy false as recommended on the few posts around the web I found but this did not help.

I'm currently running Ubuntu 17.04 with the upstream kernel 4.11.12-041112-generic (due to trouble with DP). I have tlp and the resp. dkms package installed. Any pointers as to what to try to make the batteries work as intended is much appreciated.

New information:

By now I'm running 17.10 ... still no solution :-(

My laptop has a single battery so I can't test this. I found on Lenovo support forum someone who has a problem like yours.

Basically the problem was UPower causing the laptop to shut down. One user solved the problem by removing upower:

sudo apt remove upower

If this doesn't solve the problem and/or you suffer adverse side-effects you can reinstall using:

sudo apt install upower

I had this same problem with my laptop shutdown when switching from empty Battery 1 to fully charged Battery 2.

I was able to fix this by changing the two Power functions in the BIOS to Maximize for performance instead of optimize and balanced.
