MoraleStopsHere Level 1 Level 1 (0 points)

Hello all,

 

I'm having trouble with my MacBook Pro going to sleep randomly. I will be working on the computer, and everything will go black. I can still here the computer running. When trying to wake it up from what seems like sleep, no buttons will work. The only thing I can do is do a hard shutdown, holding down power button, and then turning it back on.

 

This originally happened about 2 months ago, and only once. Since about 2 days ago, it has been happening about 2 times a day. It occurs when the temperature of the computer is cold as well as when it is warm. I am not running too many programs when it happens. I have reset the PRAM.

 

Any ideas / comments would be appreciated and helpful. Here are my system specs:

 

15 inch Macbook Pro
2.4 GHz Intel Core i5
4 GB 1067 mHz DDR3
Mac OS X Lion 10.7

 

Please let me know if there is any other information I can provide to help diagnose the problem.

 

Thanks again.


MacBook Pro, Mac OS X (10.6.5)

    Hi MoraleStopsHere!

     

     

    Could you please open your Terminal an enter the following command:

     

    pmset -g

     

    And go back here and paste the results of it. Ahh! We need also the results of the following command:

     

    pmset -g custom

     

    You could already try this command, to change your sleeping settings:

     

    sudo pmset lidwake 0

     

     

     

    greetings from Munich

    I've been suffering from this ever since I bought a MacBook Pro 17" a couple of months back. Screen goes off but MacBook seems it's still on? Hear the music etc? Have to hold down the power button to restart and lose your work? Found some forums were people were thinking it was a faulty hinge on the screen.

     

    Was using the laptop last night on the battery and then switched to the powercord, I noticed the little green/yellow light on the charger was showing fully charged when I knew it wasn't. Did some testing and found the charger thinks the MacBook is fully charged when it's not and thus not charging (when I pressed the battery check on the side it showed the battery was empty and then suddenly the powercord kicked in and started charging for a while). Using a simple app seems to be okay, start running something that need juice and thats when you get the problem...

     

    I'm guessing something wrong with the battery or charger, will once again go to the shop, will have my own parking space soon. Annoying that the Macbook doesn't warn you the battery is about to go flat...

    I've also been experiencing this problem but only since I upgraded to OS X Lion, before that this was never an issue. Also Lion seems to take forever to sleep the Macbook Pro when the lid is closed.

    I believe I have found a solution. I reinstalled my original operating system (Snow) and have had it happen only once...over the course of about a week and a half. Given, I ended up completely wiping out everything, but it seems to have solved the problem. I'm going to try and reinstall Lion, and will post if it begins to happen again.

    Hello MoraleStopsHere,

     

     

    is this probably due to a charging problem, as Puppington describes it here? If yes, you could try to reset the SMC  (= System Management Controller):

    I've noticed that my problems has stopped with only one change, I stopped playing Civilization 5. Since I've stopped playing that it's been running like a dream. So can only assume that software had some bug that screwed around with the Mac.
