vasir15 Posted November 5, 2012 Share Posted November 5, 2012 Hello, Just upgraded to 10.8.2 and sleep works with plain DSDT if I wake the machine up via power button. Now I also have a DSDT that used to wakeup the machine via KB in 10.7.5 but now if I use it for 10.8.2 the machine wakes up but blank screen. Any ideas?

p.H Posted November 5, 2012 Share Posted November 5, 2012 ATI card ? If it's, maybe you have to edit the framebuffer manually. Link to comment https://www.insanelymac.com/forum/topic/284163-dsdt-wake-only-via-power-switch/#findComment-1865122 Share on other sites More sharing options...

Hi, Sorry forgot the system spec: GA-P35-DS3L Nvidia ( apple ) PEG 12 GIG RAM Worked very well in 10.7.4 but 10.8 I am having issues.

p.H Posted November 5, 2012 Share Posted November 5, 2012 it is black screen ... system is all powered up but thats about it. I've met this before. But my hack in running on ATI card. As I've already said before, I had to modify ATIframebuffer to make it work. I guess you may solve this problem by assigning correct value to Nvcap in dsdt.

eep357 Posted November 5, 2012 Share Posted November 5, 2012 double check power management settings in bios, since gigabyte they most likely got reset if you tried sleep without AppleRTC.kext patched. Patch AppleRTC.kext then use modified DSDT Link to comment https://www.insanelymac.com/forum/topic/284163-dsdt-wake-only-via-power-switch/#findComment-1865198 Share on other sites More sharing options...
