How do I disable the hibernation setting on MBP

I have a MBP 13'' Late 2011. Since I upgraded from Lion to Mountian Lion my Mac goes into hibernation and will only wake when I hold down the power button for 4-5 seconds, release it, then press the power button again. I didn't have this behavior prior to Mountian Lion upgrade. Prior to the upgrade I would just wake by pressing the keyboard or mouse. Now once I do get it to wake with the procedure mentioned above. The screen is dimmed, a little progress indicator shows near the bottom of the screen and it takes about 40 seconds before my Mac is usable from this state.

MacBook Pro, OS X Mountain Lion

System Preferences>Energy Saver. Adjust your settings. Set Computer to sleep to Never.

I had that problem with a beta version of ML. When trying to awake from sleep, neither using the keyboard or trackpad would awaken my computer. If I pressed the power button for a few seconds, I would get a gray screen (dimmed) with a progress indicator at the bottom of the screen and my machine would finally wake up. Is that what you're experiencing?

I haven't had the problem since the GM release - thought that it was a bug that had been tackled. Apparently not. If this is what you're experiencing let me know and I'll file another bug report.

I understand that setting, however, my Mac is not sleeping, it is in a hibernating state or a deep sleep. I would like for it to save power by sleeping but not deep sleep because it is unavailable to my network and the wake from network activity does not bring it to life while in that state. If I choose as you suggested then it will never do a minimum power saving. I also have a MacBook Air and a Mac Mini both of which seem to not have that problem after they were upgraded. It is something directly related to the MacBook Pro.

Your system is not working properly. You can try reinstall ML over your present installation(backup first). This won't touch any user data or settings. You can also completely disable hibernation & only use standard sleep:

Launch Terminal & copy paste the following, hit enter:

sudo pmset -a hibernatemode 0

You can turn off the Hibernate feature. Google search turn off hibernate in OS X. It is a terminal command.

But hibernate is only supposed to kick in when the system is sleeping and then runs low on battery power.

Hi, I have the same problem with my iMac. It was fine for like a week now but it came back again. My iMac goes to Hibernation right after I put it to sleep, although I have set hibernationmode to 0. Any thoughts? Thanks.
