When the battery is discharged completely, notebooks hibernate instead of shutting down.
To prevent the battery from getting damaged, it is important that the machine shuts down.

This happens in ubuntu 15.04, power behavior was correct in 14.04 and in 14.10.
In ubuntu 14.04 default gsettings for critical-battery-action are set to 'suspend'.
In ubuntu 15.04 default gsettings for critical-battery-action are set to 'shutdown'.
In ubuntu 15.10 default gsettings for critical-battery-action are set to 'suspend' back again.

So the critical-battery-action setting has to be 'suspend' to shutdown notebooks completely!
This seems to be a little bug in gsettings, as 'suspend' setting performs to 'shutdown' action.
It leads to unwanted behavior of machines when users change power settings by executing:
"gsettings set org.gnome.settings-daemon.plugins.power critical-battery-action shutdown"
