I have no idea how to patch Power management, and HPET, so could someone help me? Battery life on this thing is just hideous on Mac. 40 minutes for Mac doing regular things, compared to 3 1/2 hours in Windows. I'd be happy with 2 1/2 hours.

It doesn't seem to be working properly, I don't get the message about Turbo ratios in the kernel.log anymore, and I still get crappy battery life ^_^

Could it possibly be the GPU that's hogging all of the power?

Been using VoodooBattery for my battery indicator for a while ;)

EDIT- Apparently the attachment didn't go through.... sorry about that. Here is the output from kextstat-

Do you have brightness & sleep working?

I have a Samsung Q310, and I wondered if any of the fixes you have applied could be applied to mine?

I do have the Speedstepping working on mine with the patches you describe, and I still get crappy battery life!

I don't think I have Speedstep enabled, and I think the GPU is using up all the battery... And the brightness was done with changing a value in the binary of AppleIntegratedFrameBuffer.kext, I can't seem to find the article right now :) I'll let you know if I do find it.

And I really don't remember what I patched for sleep... lemme have a look in my DSDT

Thanks, although looking at your specs our machines are very different!

I have an old Core2Duo while you have an i5!

You never know though? :D

They are pretty different, and Samsung most likely used a different board for it. But knowing Samsung, brightness is whacked up because it's controlled by the graphics card, which is why getting brightness control is a pain in the rear. When I did a fresh reinstall of Windows 7, the brightness switching didn't work at all, until I installed the nVidia driver. Changing that value apparently relinquishes control from that kext back to the graphics card. Considering if you have full QE/CI support of course.

Sleep- you'll probably have to figure that one out yourself... what happens when you try to go to sleep? And does disabling Legacy USB support in the BIOS help?
