External Display doesn't wake from display sleep

My display is set to sleep after an idle period (computer itself set to not sleep), when I return to the computer and wake the displays the external display most of the time does not "wake" or come back with picture. I need to disconnect the adapter and plug it in again.
Anyone else experiencing this?

Guys, please read THIS thread:
http://discussions.apple.com/thread.jspa?threadID=1760586&tstart=0
EVERYONE is experiencing this bug if you're using your new MacBook Pro with an external display. In the thread above, I detail how to fix it without having to unplug the DisplayPort adapter.
The symptoms you're experiencing are:
1.) Bizarre interference all over the external display when either a) waking your notebook from sleep, or b) turning screen on if the screen is set to turn off after x minutes.
2.) External display not actually turning on at all after either a) waking your notebook from sleep, or b) turning screen on if the screen is set to turn off after x minutes.
The fix is listed in the above thread. It's only a temporary workaround, and Apple REALLY needs to address this issue ASAP.

  • Since Lion, primary monitor doesn't wake from long sleeps

    Since installing Lion, my iMac doesn't wake properly from sleep when it's been off for a while.
    I have two monitors and the second one wakes fine, but the main one - the iMac itself - doesn't return unless I reboot.
    Any thoughts?
    Thanks

    Try turning off hibernation mode - run the following in terminal:
    pmset -a hibernatemode 0
    You'll likely need to do that from an admin account using sudo.  The reason why this happens, I think, is that you close the lid and sleep the machine while the system is in the middle of doing something (updating the hibernate sleepimage, locking the screen, etc...).  then when you open the lid, the system is still going through the close-down process and the monitor wake call gets lost in the shuffle.  turn off hibernate mode to speed things up, only turn it back on when you need it (like when you're in a situation where you'll need to switch batteries without a power cord). 

  • MBP (early 2009) won't wake from Display Sleep

    My MBP has started to not wake from Display Sleep (the machine is not sleeping, only the display). The only way to get it back is to force power off by holding the power button down.
    The weird thing is, when I power it on, it shows the 'loading RAM from disk' progress bar down the bottom of the all grey screen, as if the battery ran out. But I have it connected to a power source. Once it loads the RAM, the screen goes blank and it hangs. Another force restart and it boots to the login screen as per normal.
    One thing I have noticed is that when this all happens (ie, when I try to wake it and nothing happens) the fans are on about medium speed and its very warm, as if there is some process thats causing high CPU usage and preventing the display waking. I usually have a few browsers open, iTunes, etc, nothing out of the ordinary.
    I might try connecting via screen sharing next this happens to see if its responsive over the network -- i'll post my findings here.
    I have screen saver with password protection turned on, and its connected to an external apple display.
    Has anyone else experienced this?

    Try a SMC reset.

  • My iMac 24" late 2006 refuses to wake from deep sleep,

    My iMac is refusing to wake from deep sleep or from a shutdown, will start if I persist in either using safe mode or command mode (cmd + s)but can take many attempts, have repaired permissions and verified disk, on permissions it is constantly changing the permissions on preference panes as listed below, but this is a shortened view, there are 23 lines like this.
    permissions differ on "SystemLibrary/PreferencePanes/Displays.prefPane/Contents/Resources/sk.lproj/Di splaysPref.nib" should be drwxr-xr-x they are -rw-r- -r- -
    Would it be ok to trash the Preference Pane folder and let it rebuild ???
    Any help welcome

    Helio, you can mostly ignore repeated Permission Repairs.
    To remove Prefpanes, right click on one & nchoose Remove.
    One way to test is to Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, Test for problem in Safe Mode...
    PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive
    Reboot, test again.
    If it only does it in Regular Boot, then it could be some hardware problem like Video card, (Quartz is turned off in Safe Mode), or Airport, or some USB or Firewire device, or 3rd party add-on, Check System Preferences>Accounts>Login Items window to see if it or something relevant is listed.
    Check the System Preferences>Other Row, for 3rd party Pref Panes.
    Also look in these if they exist, some are invisible...

  • 890FXA-GD70 Will Not Wake From S3 Sleep

    890FXA-GD70 will not wake from S3 sleep; the power comes back on and the fans run but the video never returns and the system hard locks with a POST code of 22 or 24. Other than this issue the system is rock solid.
    Windows 7 Ultimate 64
    AMD Phenom II X4 955 Processor
    Sapphire 5870 Graphics
    Crucial M4 SSD
    Corsair DDR3
    No overclock
    I have reproduced the issue on two 890FXA-GD70s motherboards and I am convinced that this is not a result of a failed motherboard. I also was able to move my fully installed SSD hard drive, processor, memory and graphics card to an Asus 890FX board and successfully wake from S3 sleep proving that my OS and driver installation are working correctly.
    I know how to properly set the BIOS as I have installed many 890GXM-G65 motherboards for S3 sleep without issue. The problem seems unique to the 890FXA-GD70.
    Is there a fix for this?

    I have identified the cause. The "Extra RAID/IDE Controller" must be "Enabled" to use S3; otherwise the system will hang on the wake event. This is true even if the "Extra RAID/IDE Controller" goes unused. The "Extra RAID/IDE Controller" must be set to "Enabled" for S3 sleep to wake.
    This would seem to me to be a bug since none of the other MSI boards I have used require the optional IDE controller to be enabled in order for S3 to function properly.

  • Macboor air 13 late 2010 freezes when wake from deep sleep

    Hi. I have had this problem for a few months and still havent found a solution. This macbook air freezes and is totally unresponsive for five or six seconds when it wakes from deep sleep. I have tried:
    1 Apple hardware test, which came up negative. No hardware problem detected
    2 reset the SMC several times. No fix.
    3 repaired permissions in disk utility, and also verified and repaired disk. Still no results.
    4 restarted many times.
    5 tried booting in safe mode, but it made the machine hang.
    The only thing I havent tried yet is resetting the PRAM. in the event that that doesnt work, does anyone have any ideas. I only found thre

    I think it might just depend on how often your machine does this. My MBA 13 has done what you are describing one or twice, but its a rare event. I'm not too worried about it, but you might want to contact AppleCare and see if they have any more information...

  • My macbook pro doesn't wake up after sleep

    my macbook pro doesn't wake up after sleep

    I'm having the same issue. I've had my logic board replaced twice now, which I did last week and then Monday I had to take it to a Genius Bar again because my hard drive cable was malfunctioning. I don't know why it's happening but I'm really starting to get frustrated with my machine. I bought my MacBook Pro brand new last year in September and ever since I've dropped it in November, it's been really glitchy. After I dropped it, I had to replace my Logic board, graphics card, and hard drive and they covered it.

  • Display no longer wakes from sleep after latest updates

    G4 Quicksilver 933, nVidia Ti, 1.5GB, 20in Cinema Display
    I applied the latest updates that were pushed out recently (10.5.2 and the "Leopard Graphics Update") and now my Apple display will not properly come up when I wake the box from suspend.
    That is, it starts and runs fine, but if it goes into sleep, upon waking it will (sometimes) flash the contents of the desktop, and then go black. The litte green light is on. Happens from a logged in session, or from the main login screen.
    I have to hit the reset or power button (or login via SSH and issue a shutdown) to get it to work again.
    I only have a single monitor.
    I tried:
    o Powering the monitor off and on, both from the switch and by pulling the power cable
    o Pulling the DVI cable and reinserting it
    o Resetting NVRAM
    o Re-applying both the 10.5.2 combo installer and the Leopard Graphics Update 1.0 in order
    o Waving a magic wand... I mean, fixing permissions
    o Changing the display resolution a few times
    o Running fsck a few times (only because all these unclean shutdowns are making me nervous)
    o Hitting the "Detect Displays" button in the Displays Prefs panel...
    Aha! Hitting that button causes the display to flash and then go dark. I have to power cycle the unit to get the monitor to come up again.
    I do have the special build option of the faster video adapter which was available all those years ago. It's quaint now, sure, but it was a fast card back then.
    I'm stumped. It's surprising how something like this can turn a perfectly reasonable desktop into a boat anchor.

    This Discussion is marked as Answered, but with my apologies to the other respondents, it is NOT. There is a problem. The software/hardware do NOT work as they are supposed to. Apple needs to address this problem immediately. Mac Book Pro will not wake from sleep when connected to a Cinema Display 23". The problem lies in the most recent operating system updates. Before the update the products worked as advertised, since then they do not. Period.
    With all due respect, I am the one who posted this, and I marked it "answered." Yes, there very well may be a problem with the Leopard Graphics Update 1.0 (what a mouthful! I dub it "LGU v1.0" from this point on.), but this is so far only a hypothesis.
    I found an immediate workaround which suits my purpose. If this does not suit the purposes of completely foreign (to this discussion) symptoms related to Intel-based Apple laptops and external displays, then so be it. I recommend splitting off your own symptoms to a new thread.
    Certainly, my reading of the symptoms described after I posted mine mostly do not sound like what I ran into at all. For example, I never once said that my computer had problems waking from sleep. I said the /display/ had problems waking/starting up after sleep, and this is probably related to the "detect displays" mechanism that the OS uses to find attached displays when it comes out of suspend. Even if this is my misunderstanding it does not matter, since this is how it comes across to a reader. This may indicate that someone may want to clearly and carefully describe /exactly/ what they are seeing, and the steps they took in order to come to any conclusions they might have.
    This will help Apple, and it will certainly help others that search these threads with their own similar but different issues they need solved.
    If there is a common reproducible issue related to displays and the most recent update(s), then Apple already knows about it, or soon will. As far as my immediate needs are concerned, this is answered.

  • Cinema Display won't wake from sleep

    After reading lots in the forums I've concluded lots of people have the same problem that we are mistakenly thinking is specific to a particular monitor or Mac or behaviour.
    Problem: Display suddenly does not wake from sleep - incidentally after an OS update and Cuda update.
    Hypothesis: This definitely seems like a software problem as I've solved it in so many new ways. (Some people are replacing hardware!) Once fixed, the problem recurs the next time the display goes to sleep. However solutions rarely work a second time.
    Solutions:
    1. Zapping PRAM fixes it.
    2. Deleting all displays preferences fixes it.
    3. Safe boot and clear caches may have fixed it.
    4. Pulling the Mini DisplayPort cable and blowing on it has fixed it. (I thought it was dusty since it worked. It may have just been pulling the cable.)
    5. Deleting a power management preference in System/Library/SystemConfiguration/ fixed it.
    6. Moving the power plug from one slot on a power bar to another fixed it. (***!?!)
    7. Creating a new user account fixed it.
    8. Now I'm stuck.
    Please can help me think of a new way to fix it? If I can get it going again, I will simply keep the computer and 2nd display awake forever.

    I have a new fix!
    8. Launch Magic Bullet Looks app and fiddle with the display settings!!! Woohoo! I got it back again.
    As long as the display never goes to sleep and is never unplugged (tried that) I can keep using the monitor. Sadly this means never lettting the new iMac sleep. 

  • MBP15 Retina: Cant wake from Display Sleep

    I've bought my MBP15 with Retina a week or two ago.
    You know how your display turns off after a minute of leaving you Mac idle?
    When I touch the trackpad or any key on the keyboard to log back in, the display turns back on for 1 second, then goes black again.
    It continues to do this everytime I touch a key or the trackpad. Turns back on for 1 second, then turns off again. I can't log in, and have to force-shutoff the Mac to get back in.
    This is very unfortunate, as I'm from Guatemala. We don't have Apple Stores here. So I can't just walk in and get it serviced.
    Anyone has a solution? I've already done a permission fix on the Disk Utility, to no avail.
    + If I close the lid to make it sleep, then open it up again, it turns back on no proble. It's only when the display sleeps.
    Thanks so much everyone.

    Hi Nikolaus
    I have the same issue. Having got myself in the habit of a quick swipe across the Magic Trackpad to reawaken my external 27" display from display sleep, this bug is very annoying. It happens for me when connected to AC power, so the problem is not restricted to running off battery power.
    I shall report this as (another) Lion bug here: http://www.apple.com/feedback/macosx.html
    Please feel free to add your own complaint, too - the more the merrier

  • Help! 2010 imac 27" - Display doesn't work after long sleep

    I just recently started having this problem. I've had this iMac since 2010 with zero issues, but it seems like ever since I downloaded Yosemite, the screen won't work after the computer has been sleeping for a while. I have to hold the power button and do a hard restart to get it to work again. If the computer has only been sleeping for a while, it wakes just fine. It's only after it's been sleeping all night and I go to use it agsin. I've checked power connections and all is good. Any ideas??

    Hi Punisher8522,
    Welcome to the Support Communities!  The resource below offers some troubleshooting steps to try when your computer won't wake from sleep.
    OS X: When your Mac doesn't sleep or wake - Apple Support
    http://support.apple.com/en-us/TS5357
    Your computer cannot wake from sleep
    Make sure your computer isn't powered off by pressing the power key for one second.
    If you're using an external display, make sure your display is not powered off or unplugged.
    If you are using a Mac desktop:
    Make sure the AC power cord is connected securely to the computer and outlet.
    Make sure the AC power outlet it is connected to is working properly.
    If your computer is plugged into a power strip, make sure the power strip is not turned off. Check to make sure other items connected to the power strip are receiving power.
    Your computer is slow to wake from sleep
    If you see a progress bar when you wake your computer from sleep, this is normal. The computer is waking from safe sleep.
    OS X Recovery and sleep
    The system software your computer uses when started from OS X Recovery allows display sleep. Your computer does not go to sleep on idle while started from Recovery unless you are using a Mac notebook that is not connected to AC power.
    Additional troubleshooting
    If the steps above do not resolve your sleep-related issue, try these additional recommendations.
    Reset SMC
    The System Management Controller (SMC) is involved in managing power on your computer. Reset the SMC on your Mac if you are having difficulty sleeping or waking your computer.
    Reset NVRAM/PRAM
    Nonvolatile RAM (NVRAM)/Parameter RAM (PRAM) stores some power-related settings.Try resetting NVRAM/PRAM if you are having difficulty sleeping or waking your computer.
    Test with external devices disconnected
    Some external devices can prevent your computer from sleeping. Try disconnecting items other than your Apple keyboard or mouse from the built-in USB, Thunderbolt and Firewire ports on your Mac. If this resolves the issue, try reconnecting your external devices one at a time until you find the device preventing sleep or wake. Check the documentation that came with the device, or contact the device manufacturer for more information.
    Try Safe Mode
    Check to see if the issue still occurs when the computer is started in Safe Mode. If this resolves the issue, it could be related to a third party software item such as:
    a login item
    a startup item
    a third party kernel extension
    Try another user account
    Try creating another user account, or log in as guest. See if your computer sleeps and wakes properly from the additional user account. If it does, your issue may be related to one of the following:
    a login item
    an app open in the original user account
    You can disable login items from the Accounts pane of System Preferences. Try opening only one app at a time in the original user account to determine which app is preventing sleep. If you isolate the issue to a particular app or login item, check its documentation, or contact the developer of that software for more information.

  • Macbook air doesn't wake from sleep

    Since upgrading recently to Snow Lion my late 2010 Macbook Air won't wake from sleep mode. I have a second monitor. After sleeping I hbave to hit the ctrl-alt-power to get it to boot up which is does as a normal cold start. I have power sleep turned off. Ideas?

    Later today I disconnnected my 17 inch monitor and put the mAcbook Air to sleep from the Applpe menu. 1st thing, it didn't want to go to sleep. Finally it did. About 3 hiours later I opened the lid or hit space (I forget which) and the screen lit up to where I had left it.
    That woukld seem to suggest that somethihng is going on with the monitors preferences, or whatever, as before updating to Mountain Lion I had no sleep problems. What now? Reinstall Mountain Lion or?
    TIA, BIll

  • NEW iBook and doesn´t wake up after sleep mode!

    Hi,
    I´ve just started to use my new iBook G4 3 days ago, added my user information, and for a little while the wireless internet connection. Then, I closed the display to put it on sleep mode.....and.............it DOESN´T WAKE UP!!!
    The hard disk seems to start up correctly (the fan is on and the disk noise is ok), the Caps Lock on the keyboard is on too, but as soon as I reboot the computer, a strange beep (like a phone tone!) starts up, then the sleep light signal flashes but the screen stays black.
    I think that by now I´ve tried the most solutions (as far as I can having the black screen) I´ve read on the troubleshooting page and the recommendations posted in this Discussion chat... The iBook remains partially dead.
    Help!!!

    ummm, even when its not plugged in to the power adapter? i find that when my ibook annoyingly doesnt wake from sleep, its usually because i connected/disconnected something while it was sleeping. even plugging in the power adapter seems to affect it. the way i fix it is to put it to sleep again, and then open the lid. its worked every time so far.
    oh, and apprantly 'manually' putting the ibook to sleep does the trick (ie from the apple menu)
