steftrikia Posted October 5, 2011 Share Posted October 5, 2011 Hi everybody, I'm using Lion 10.7.1 on a mini-ITX Asus Moca-ar motherboard, with nvidia 8400GS graphic card, and a T7200 core 2 duo. Everything works fine except wake from sleep. When I try to wake from sleep, the fans wake up but the screen stays off. I have to force shutdown with the power button. I can't even access to the computer via ssh. I have tried to : -patch my DSDT with _WAK fix -change my graphic card (same problem so I don't think it's the cause) -change all versions of sleep enabler -change processor (same problem with a core duo) The computer boots without disabler.kext and speedstep is active. Only the C-states aren't recognized (the command 'ioreg -lw0 | grep CSTInfo' returns nothing) I tried everything from my poor knowledge, and I've read lot of topics about this problem, but I never found any solution. Now I really need your help please. Thanks for advance Link to comment https://www.insanelymac.com/forum/topic/269619-black-screen-after-wake/ Share on other sites More sharing options...
