hello walterav, thanks for your response and I am sorry for not answering sooner but I am still testing various DSDT modifies .
My sleep worked native in 10.5.5 and not anymore since 10.5.6. Since then I was using superhai's EHCISleepEnabler.kext and sleep was working again in 90 % of the cases.

But since I installed SL I have no "sleep" at all ( my system won't go to sleep everything stops except the fans, the green power-led remains still and I have to reset the system from the reset button) Also when I reset the system from sleep it screw my bios settings.


I am still testing the audio ( no luck until now) by the way, in bios I try to set both way (hd audio and ac97) in the onboard device conf and nothing changes regarding the Headphones so I was wondering what did you put there hd or ac97 ?

I also intend to reflash my bios on 1202 ( I now have the latest 1305 I think)
