dodox Posted September 26, 2012 Share Posted September 26, 2012 Hello, I have a interesting sleep problem. I installed Mountain Lion and if I activate the sleep the following happens: 1. The Screen turns off (at the exact time) - The computer fans and drives are still running. 2. After a time (minute to 1h) the computer goes into sleep! (I can wake it up normally). So any ideas ? Thanks Gigabyte Z77 DS3H (F8) Intel i5 2500K 8Gigabyte RAM 480 Watts Power Supply EVGA GTX 460 ML 10.8 Edit: If there is a topic with a similar problem - please tell me the link instead of saying "use the search". I google for over 2 weeks now to get it run ! Link to comment Share on other sites More sharing options...

ctroncosor Posted September 26, 2012 Share Posted September 26, 2012 Check PRW and PSN in DSDT Link to comment Share on other sites More sharing options...

fantomas Posted September 27, 2012 Share Posted September 27, 2012 Mac Pro 3,1 is for LGA775 socket and you have a LGA1155 ! You have an Ivy Bridge config so use an appropriate SMBios ! Try iMac 12,2 SMBios; you can use Chameleon Wizard to edit your actual SMBios or to create a new one ! Link to comment Share on other sites More sharing options...
dodox Posted September 27, 2012 Author Share Posted September 27, 2012 I read this, too. But it doesnt help I dont understand why its just me with that problem. Windows has no problems with sleep. Any other ideas ? Link to comment Share on other sites More sharing options...
