The answer for how to enable laptop mode is not in "man laptop-mode.conf". I fiddled with
that, and tried to run /etc/init.d/laptop_mode, and tried to run laptop_mode init.
laptop_mode status says "Laptop Mode is NOT allowed to run: /var/run/laptop-mode-enabled does
running sudo laptop_mode gives the unhelpful and contradictory:
Laptop mode disabled, active.
So even though cat /proc/sys/vm/laptop_mode says I'm in laptop mode (2), my cycle count
continues to increase at a rate of one/minute.
