Since I installed Mountain Lion, my macbook pro (middle 2011) does not come back from a deep sleep. It start loading but in the last part it's freeze and a sound came up (beep,beep, beep...) constantly. I had to force a shutdown and then power up again.

A normal suspend work just fine, and all my prior software too.

What could it be???

 

Many thanks in advance.

    3 beep code on waking from sleep.

    Did a fresh install that did not fix the problem.

    sudo pmset hibernatemode 25 worked for me. 

    Even hybernates faster now and sticks over reboots.

    I'm sure we will see an update from Apple within the next week.

    I suspect now that some widgets, and apps are setting bad hibernatemodes.

    I used pmset -g, and it said I was in hibernatemode 5. I set this (sudo pmset -a hibernatemode 0) closed the lid, and it came back up. I set it to 3, and the same. I moved over to my widget, and set it. Checked my mode, and it was back to 5.

     

    I used `man pmset` it said to only use mode 0, 3, and 25! No others! I again set it (sudo pmset -a hibernatemode 25) this time to 25, and it seems to work fine.

     

    I suspect Apple made changes to their power managment, and disabled older modes. They should have set this correctly in our upgrades, instead of letting us figure it out.
