Details

Description:
systemctl stop laptop-mode.service does not actually disable laptop-mode

It looks like systemd is trying to pass laptop-mode-tools the 'stop' and 'start' commands like this:
ExecStop=/usr/bin/laptop_mode init stop
ExecStop=/usr/bin/laptop_mode init auto

The author notes in #4 in this faq http://samwel.tk/laptop_mode/faq
"Note that the /usr/sbin/laptop_mode command does not support the "start" and "stop" commands anymore. These commands interfere with the low-battery detection code, and they default to "auto" for that reason."



Additional info:

Reason for closing:  Upstream
Additional comments about closing:  Closing tasks for the recently dropped laptop-mode-tools.

This looks like an upstream bug, we don't do any changes to the systemd startup script.

The systemd unit file comes from upstream, so please report this problem to the upstream developer: http://www.samwel.tk/laptop_mode/

Interesting. I sent him an email and he noted that systemd was new and perhaps to file a bug with you guys. Will respond back to him again.
