Or perhaps by these changes listed in the changelog:
* Improve battery life on laptops (Closes: #898629)
Thanks to Hans de Goede <[email protected]>
- 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.
