I have a ThinkPad T400. I was running Fedora 12. I formatted the 
partition and installed Fedora 14.

My power consumption as measured by powertop went from about 17W to 
about 27W after using all of powertop's suggestions, as follows. The 
machine starts at 32.3W.

- increase writeback time
- enable USB suspend
- turn on HD audio powersave
- disable bluetooth
- enable wireless power saving
- enable runtime power management
- SATA power save

The it continually shows these two:
hwC0D1 Conexant 2c06
hwC0D0 Conexant CX20561 (Hermosa)
are busy 100.0% of the time.

What can I do to save power and get back to my former (or better) power 
levels?

Thanks,
Chris
