Bug ID: 1080006
           Summary: Incorrect command for multi-core power saving
           Product: Fedora Documentation
           Version: devel
         Component: power-management-guide

Description of problem:
In section 4.2
[https://docs.fedoraproject.org/en-US/Fedora/20/html/Power_Management_Guide/E...],
there's a list of commands that can be executed to save some power.  The
command listed for "enable multi-core power-saving (part of the
laptop-battery-powersave profile)" is a duplicate of the previous command and
is therefore incorrect.

Version-Release number of selected component (if applicable):
1.1-0

The command is given as:

echo Y > /sys/module/snd_ac97_codec/parameters/power_save

Which is the command for enabling audio codec power saving, not for enabling
multi-core power saving.

--- Comment #1 from Andrew Aylett  ---
The RH docs[0] suggest that the command should be this:

echo 1 > /sys/devices/system/cpu/sched_mc_power_savings
