I have a early 2011 macbook pro with mountain lion 10.8.2 installed in it, I have sleepawake installed and disabled energy saving option all set to forever.

energy perferences

the problem is the system is still going to sleep randomly without any sort of common behaviour , I reinstalled ML and still no luck, this problem was there before but it happened maybe once in several days, now it is much more frequent and can be triggered even by spacebar press or nothing at all, what can be reason for this.

here are list of kexts in my system

Does it happen while plugged into an external display? –  segiddins Jan 6 '13 at 21:50
    
no monitor or any external device is involved, except mbp with it's magsafe adapter. –  Vaibhav Mishra Jan 6 '13 at 22:07
    
Try installing and activating Caffeine, and tell me if it still sleeps with that on. –  segiddins Jan 7 '13 at 1:21
    
caffeine or any other such program has no effect. –  Vaibhav Mishra Jan 7 '13 at 5:53
    
Have you tried resetting the SMC? –  segiddins Jan 7 '13 at 12:13

I hunted that for a while on my MBA 10.9.2.

To my shame it was the Hot corners setting :(

hot corner

So when ever the Mouse was there it obeyed the command.

I had this exact same problem and it completely befuddled me for a WHILE. Apps to force it to stay awake, like (I assume) caffeine had no effect. Finally while looking at the logs, I saw that what was happening was not that it was going into sleep but rather that it was going into clamshell mode, meaning it was doing what it was supposed to do when one closes the Macbook. I took it into the Apple store since it was under warranty and told them all of this and sure enough it was a problem with the magnetic sensor in the case that detects whether or not the clamshell is closed. They were able to test it quickly without needing to open the case with the use of a magnet that they waved over the case.

I'm sure you could test for it this way yourself but if you don't want to go see Apple (which I actually suggest that you DO because you're going to need a new sensor anyways) you should check the logs to see what's actually happening when it is doing this. It sounds to me very much like this is probably what is going on and if you check the logs you'll know for SURE; if it says it's going into clamshell mode then it's the sensor and it simply needs replaced.

Replacing the sensor solved the problem completely.

If it is not going into clamshell mode then I do not know what to tell you except that at least it didn't hurt to take a look at the log, right?

MBP Mid 2009 thinks the lid is closed permanently - this is a link to someone who had the same problem; they posted their logs if you wanted to see what the log will say.

Hope this helps.

check system.log here's a link on how to view log files tech-recipes.com/rx/3521/os-x-how-to-view-log-files –  Ron Kyle Oct 29 at 23:09

I have the same issue. I even installed Caffeine, and it still would go to sleep randomly. Screen "goes black" while I'm using the Macbook Pro early 2009 with OS X 10.8 with present day updates. If I touch the trackpad while the screen is black I hear some noises like the computer is waking up again and it comes back on. Randomly, could be minutes, seconds, or hours it happens again, sometimes several times in a row.

PRAM reset and SMC reset did nothing as well, I even reinstalled OS X and it was doing it during the install, tried the hardware test, everything passed but it was even doing it during the hardware test.

It never happened until I updated to 10.8.

Someone mentioned typing this in the terminal and resetting the computer

sudo rm /private/var/vm/sleepimage

I'm going to try that and hopefully it works.

hey, I am also having same issue, does sudo rm /private/var/vm/sleepimage worked for you? –  Awais Tariq Jul 31 '13 at 18:36
