Disk-idleing (aka "laptop-mode") and power states are quite separate things. https://wiki.ubuntu.com/PowerManagement
Since ubuntu by default ships with laptop-mode-tools (thus disabled) which handles all the things associated with disk-idleing,
(like mount options, hdparm options, low battery exceptions, disk-idleing on AC when on the road, etc.)
just remove the "laptop-tools" script from pm-tools.
Package laptop-mode-tools needs to put scripts in that place if pm-tools are chosen to handle power states. #244844
