My system does not hibernate or suspend automatically when asked to in dconf configuration files. I have tried some workarounds and I eventually found a script that used to work however with a new fresh installation of Ubuntu the script just poweroff the whole system (Won't Hibernate when Battery Critical - answer by Goghard). I also tried to modify the grub file by myself, with no success unfortunately.
My ultimate scope is to suspend the system at a critical level defined by % battery level.
I attach also the partitions of my system, I added recently another swap partition to attempt to fix the problem.
