The pm util power saving scripts only work when a laptop is on battery, not when it is plugged in to AC. Is there a way to make pm utils run all the time, regardless of whether the laptop is connected to a power outlet or not?

You can enabled this using:

sudo pm-powersave true

or if you want, I guess you could add the following to /etc/rc.local:

pm-powersave true

You can make a script

 sudo gedit /etc/pm/power.d/power

Copy paste the following the following in power file

#!/bin/sh

# Shell script to reduce energy consumption when running battery. Place
# it in /etc/pm/power.d/ and give execution rights.

if on_ac_power; then

# Start AC powered settings #

pm-powersave true

else

# Start battery powered settings -#

 pm-powersave true


 fi

Now you need to assign execution permission of power script

 sudo chmod +x /etc/pm/power.d/power

Now you will have pm-powersave true on both ac/bat

How do I make Powertop changes permanent?
