Hi! I seem to have the same problem on my T460s and it is impossible to suspend the laptop (lid close or systemctl suspend). As far as I can remember, the problem appeared with kernel 5 branch (bpo on buster). At that time I did not wanted to open a bug report because I was not sure of my installation (dist-upgrade from buster, plus lots of bpo kernel installation and test) and I had found a workaround for the suspend problem, using those commands after reboot: | echo reboot >/sys/power/disk | echo disk >/sys/power/state Now I have a clean Debian 11 installation and both suspend and poweroff does not work anymore. I am happy to help to debug this if needed. Cheers! Faustin
