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

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 !

Board has UEFI - does not require DSDT :(

Updated to 10.8.2 - still the same problem :(

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 !
