Fedora 18 Power Management Issues on MacbookPro 8,2

edit

Hello all,

I have a MacbookPro 8,2 that I was running Fedora 17 on and upgraded recently to 18. Since then I have noticed a major increase in power consumption. On F17 I had a relatively bad 19-20W base power consumption (I believe mostly due to using non-EFI boot and not knowing how to turn off the ATI graphics card), but now I am at an even worse 29-31W.

Looking at PowerTop, I believe the problem is that I see 100% usage for nearly all my PCI devices. e.g. here is one screen cap of my Device stats:

The battery reports a discharge rate of 29.7 W
