Powertop makes suggestions. We wish it wouldn't, because they're often either things the OS could get right for you, or things that actively degrade the user experience beyond their powersaving karma. This is a list of the suggestions it makes, and what we plan to do about them.

Various kernel config options

Disable the unused bluetooth interface

Enable the ondemand cpu speed governor for all processors

Disable Ethernet Wake-On-Lan

Enable laptop-mode

Disable the NMI watchdog

Enable the HPET in your BIOS or add the kernel patch to force-enable HPET

Enable AC97 powersave mode

Enable the noatime filesystem option

Enable the power aware CPU scheduler

Increase the VM dirty writeback time

Enable SATA ALPM link power management

Enable USB autosuspend

Enable wireless power saving mode

Disable the unused WIFI radio

Disable TV out
