PM-POWERSAVE(8) pm-utils User Manual PM-POWERSAVE(8)NAME
pm-powersave - Put your computer into low power mode
SYNOPSIS
pm-powersave [{true | false}] [--help]
DESCRIPTION
This manual page documents briefly the pm-powersave command.
pm-powersave can be used to set your system into low power mode.
OPTIONS
true
Put the computer into low power mode to reduce energy consumption and extend your laptop's battery life.
false
Turn off low power mode.
--help
Show the help.
FILES
/etc/pm/power.d/, /usr/lib/pm-utils/power.d/
When you run pm-powersave it combines the scripts in these two directories and executes them in sorted order. If both directories
contain a script with the same name, the one in /etc/pm/power.d/ has a higher precedence and only this one will be executed.
Therefore to disable a script from /usr/lib/pm-utils/power.d/ simply create an empty file in /etc/pm/power.d/ with the same name and
without the executable bit set.
