I've had my MBP 2011 for less than a week. This happened once before, but I shrugged it off, and now it's happened a couple times just today. This happens when I close my computer and it goes to sleep. After I open it, instead of waking normally and functioning, it either
a) does not wake from sleep, screen stays black (so far I've simply closed it again for a few seconds, and opened it again and then the screen will come back)
b) wakes from sleep, goes to normal screen for a second, then the blue screen for a second, and then comes back to normal

Any ideas why this is happening or how to fix it?
Thanks in advance.

Macbook Pro 2010, Mac OS X (10.5.8)

    I have the same issue. Apart for closing the mac and going to sleep, I plug an external display (dvi), and then when unplugging it and opening the mac, it happens the same. Also I noticed that sometimes it does actually wake, but the brightness is messed up, the meter says it's at half but the screen is not really on, and if I increase the brightness to the max, the screen will only top to the half its max.

    I've read and looked for possible solutions, reseted the SCM, PRAM, and finally reinstalled the system. I haven't plugged in an external monitor after the reinstall, but when I close and put the mac to sleep, at least it wakes normally now.

    Thanks for your response! In resetting the PRAM and SCM, are there any risks to losing anything on my computer (sorry, I've never had problems with my macs before getting a MBP so I don't know anything about fixes)? Am I better off seeing a genius about this?
    Thanks again.

    I'm relative new to macs also, I just looked for in the internet, and it seems that there's not risk at all of resetting the PRAM or SCM.

    But again, these 'solutions' didn't work for me, so I had to go further and reinstall the system.

    So yeah, I plugged in an external monitor yesterday, closed the lap, and then unplugged the monitor after some time of work, opened the lap again and no brightness... The screen was working, but no brightness on it. I checked the console log and got the error:

    <Error>: kCGErrorIllegalArgument: CGSGetNumberOfDisplayModes


    So no, reinstalling the system didn't work at all. Sigh...

    I have the same problem. I have a 15" mbp 2011 connected to 27" ACD.


    Also unplugging the power from acd doesn't help. Once in this state the mbp doesnt start even after holding the power button. Only by connecting the mbp power supply I am able to start the mbp. Wondering if acd is causing the problem.


    Bought mbp last month.

    I have the same problem. 2011 15" Macbook Pro 2.2GHz Core i7.


    Pressing the F2 (brightness) key once fixes the problem. Apple needs to fix this!

    Hi guys!

    First I want to say I am new in this Mac World and I am glad to be one part of the family!




    I have the same problem with my MacBookPro 13" i5 2011 MacOS 10.6.7. Sometimes when I close the lid and open it again I get a black screen. Last time it happen I tried to hit Space and my computer made a sound. I am not so familiar with all the sounds in MacOS yet but I think it was a problem sound. I had to push the power button and restart my computer.


    I think I was charging it and then I closed the lid, unplugged the power and then open it again or plugged in the power and then open it again. I don't remember but I got black screen. Sometimes it very slow to before it come back. If I don't remove the power contact I think it wakes up normal directly. 


    I will try the stuff you have write here and see if it's working.

    Hey all,


    I had the same exact problem on my 2011 MacBook Pro. For me it was every time the computer went to sleep. The only way I could get the screen back was to close the lid, wait, and open it again.


    For me the problem was without a doubt my installation of "Air Display" by Avatron Software. If your not familiar with what it does than that is probably not your issue, but it allows you to span your screen to an iPad on the same WiFi network.


    As soon as I uninstalled Air Display my problem went away and the second I reinstalled it the problem came back. So if you are having this problem and have Air Display installed try uninstalling it to see if that helps.


    To uninstall the Air Display support software on Mac OS X, launch the “Uninstall Air Display” app in Applications > Utilities.

    My experience is the same. With Avatron's Air Display installed I have two issues (below), when I uninstall Air Display they go away.


    I have a new Macbook Pro, 2.3 GHZ Intel Core I7 running OS X 10.6.7. All system (and firmware) updates installed.


    I mentioned two issues when I have Air Display installed.


    1. During the boot process the screen briefly shows what appears to be corrupted video memory. See this image of the screen.

    2. I have the black screen on wake issue as described here and elsewhere.


    I don't know that they are correlated but it seems reasonable to expect they are. In any case, both issues appear to go away immediately when I uninstall Air Display using the provided uninstaller.


    I have tried touching the Extensions folder, booting in safe mode, etc. I have spent many many hours (more than I care to remember) trying to narrow this down, and I think this is it. I will leave it uninstalled for a few weeks and see.

    I have similar issues but I don't have Air display installed. this problem has been become serious after I upgraded to 10.6.7. I can't connect to external monitor at all with lid closed not. I'm pretty stuck if I can't figure a resolution.

    It work for me too. Firewire external disk close and reopened. I don't think this is not good for data.

    Sorry, I do not have the solution, but I hope Apple read this

    I noticed that when I got the black/sleeping screen my MBP was not plugged to power source. I simply connected it to power source and the screen brightened up and showed the login (my MBP had got locked).

    I think it's something to do with screen brightness. Next time I am gonna try the F2 key solution suggested by HTowner . I have a feeling it'll also work as F2 key is for increasing the brightness.

    Ok, please copy & paste this command in Terminal:


    pmset -g | grep lidwake


    If the number is a 1, then your fine that's not the problem.

    If it's a 0, then there's your problem.

  • PVerro Level 1 (0 points)

    Thank's AussieDJ,


    That was not the problem, nice to you.

    It's a rapid verification to all to try.
