I usually write hdparm -B 254 /dev/sda to the /etc/rc.local to set the APM 254 or 255, so if laptop-mode-tools only do the same unfortunately it won't be enough.

For example my harddrive is Seagate ST9120822AS. If you check https://wiki.ubuntu.com/DanielHahler/Bug59695
it shows there is no known safe APM setting exists to this hard drive. In the earlier Ubuntu distributions I tried both 254 and 255 but they didn't solve the problem for me.

For many hdd it shows solution but for mine and some others there isn't any known solution.
