Or perhaps by these changes listed in the changelog:

  * Improve battery life on laptops (Closes: #898629)
    Thanks to Hans de Goede <hdegoede@redhat.com>
    - ATA: A new SATA link-powermanagement-policy will be the default on all
      Intel mobile chipsets. This can be reverted by passing 
      "ahci.mobile_lpm_policy=0" on the kernel commandline.
    - sound: Enable Intel HDA codec power-saving by default with a 1 second
      timeout. This can be overridden by passing "snd_hda_intel.power_save=0"
      on the kernel commandline (0 is previously default).

The hints there are meant as workarounds.  Let us know if they work for
you.  We can disable power-saving by default on specific hardware where
it doesn't work properly.

Ben.
