IMac :: Black Screen Display When Wake Up From Sleep
Dec 21, 2010
For the past few weeks it has been going to a black screen when trying to wake it up from sleep. Either I've put it through too much work lately editing all these photos and its really tired. So, often it wakes up normally and functions fine, well, not really. It is seemingly very slow. It requires a lot of time (more than before) to open up a program or it gives me the "spinning wheel of death" when trying to go to a different page on the internet or open up a folder on my desktop. Amongst other things that require it to think. So It's just a lot slower in general than before.

I've noticed that when my rMBP (late 2013, Mavericks) turns off the display automatically while on battery (as configured via Energy Saver) and I try to wake it immediately, I get a black screen with the cursor, rather than my password/unlock screen. It remains a black screen, with the cursor moveable, for 5-10 seconds or so, and then the password/unlock screen will appear as usual.Â
This does not happen if:I don't try to wake the display/computer immediately after automatic display sleep (e.g., I wait 5-10 seconds and it's fine)I turn off the display using a hot corner and immediately wake the displayI put the computer to sleep by closing the lid and immediately wake it by opening the lidI select Sleep from the System/Apple menu and immediately wake it by pressing a key or clicking on the trackpadÂ
Why automatic display sleep is causing this temporary black screen? I currently get around it by setting the time for automatic display sleep while on battery to 10 minutes instead of the default 3 minutes to minimize the chances of needing to immediately wake the screen. I'd like to keep it at 3 minutes if possible to maximize energy savings, but the temporary black screen is really annoying if I didn't really want display sleep and consequently have to wake immediately.

I have very recently upgraded to Lion on my late 2009 Intel Core 2 Duo iMac. When the machine goes to sleep on wake up - instead of going to the log on screen, the display remains black but when I move the mouse the display creates a grey pixel trace wherever the pointer should be. I also end up with the desktop clock in the top right.
To log on, I have to literally "colour in" the area where my profile icon should be which enables me to input my password. Also, on wake up, any applications that I had open like Safari, Word, iTunes etc are all closed and not open in the dock. On a separate matter, when this happens I cant wake my imac up to access my itunes library for home sharing on my ATV3 and 4S.

When I wake from a long sleep, my screen comes on but everything is black. If I move my mouse around, the tiles behind the pointer switch over to whatever app is open. When I invoke expose/spaces, the screen fixes itself and displays everything.

In the last 2 months or so, I have seen my MacMini 2011 OSX 10.7.3 crashing withing a minute of wakeup, after sleeps of more than 2-3 hours.Â
Sometimes the Black screen occurs almost immediately, sometimes it takes up to a minute after the desktop appears (after logging in). This did not occur until I got 10.7.3 and only within the last 2 months.

I'm using an iMac (late 2011) with 10.7.3. I'm doing things on the computer or some process is going on when the screen instantly goes black (no dimming first). If a video was playing, I can still hear it playing, but pushing keys on the keyboard or mouse or pad does nothing to wake the screen. Sometimes pushing the power button a number of times will get the screen to come on, sometimes it won't. When the screen goes black, if an external drive was running and then stops, I can sometimes get the screen to come to live. Sometimes this black screen happens when I'm burning a DVD; when the DVD is finished, I can bring the screen to life. I thought one of my two external drives was bad, so I disconnected it. That seemed to help (though verifying the disk revealed no problems). But a few minutes ago, the screen instantly went black again; no dimming first. There have been times I thought this was associated with a new bit of software, but then it returns even after I delete the suspect software. Sometimes I have to use the power button to shut down the iMac then restart it. Once, I had to unplug and replug the iMac before I could get the computer to respond and the screen to return to life. I don't know if this is a hardware problem (internal or external), a software problem, or some combination...or something I haven't thought of, at all.

When I need to go somewhere or just eat lunch, I put my iMac to sleep. After that, when I come back to wake it back up, it stays black.

This just started yesterday (May 31st). I keep everything updated as it comes out and nothing new has been installed in the last couple of days.
When I need I wake up my iMac (now requiring a keystroke or mouse press instead of just moving the mouse), the screen comes up black, but the cursor is there and moves around fine.Â
It stays black for a while (15 seconds or longer, but it feels like forever) and then it finally comes up completely.Â

After my 27" i7 wakes up from a long sleep (roughly over 1.5 hours), something very odd goes on with my color profile and/or screen. Approx. 5 second or so after waking, the screen color appears to wash out quite a bit. You certainly have to be quick to notice it, but something is definitely going on.

I came back from work to wake up my iMac. It made the noise but the screen stayed black. I tried restarting by holding the power button- I can hear it start and the chime but still have a black screen. I tried resetting the pram, and unplugging the cord but I still get a black screen. I can hear the chime though; I'm not sure if that means anything. I just had the hard drive replaced in February so I hope it's not that. just wanted to clarify that when I restart, I get the chime but the screen stays black- I don't get to the grey screen. So I'm assuming right now that my display may be shot?

I have a 2 month old 13" MBP which I absolutely love. The only hitch is that there is an oddity when connected to my Dell 2008wfp display. It only happens when I wake the MBP from sleep. A number of things happen sometimes. Usuaully, when I wake the MBP from sleep, i get a black screen on both displays and all I can see and control is the cursor. Sometimes the main display will be black, but the MBP display will show the desktop wallpaper, but again, I can only see and control the mouse cursor. It should also be worth mentioning that the keyboard is rendered non-functional as well.
Sometimes, OS X will appear on both displays, with mouse cursor active, keyboard inactive, but I am unable to click anything or interact with anything OS X.
Anyway, I'm at the point where I need to mention this because it happens quite frequently and its getting rather annoying. The only way I can get out of this hang, is to cold reboot the machine. It happens everyday and at least 50% of the time I wake the MBP from sleep. When not connected to the display, I never get this occurrence. Also, this display worked perfectly when I used to own the classic 15" MBP, so its hard for me to pinpoint what exactly is the anomaly that is happening.
Anyone else experiencing this same issue? I am using a mini display port to DVI adapter to the Dell display.

Only way to recover is hard restart. Just downloaded Lion two weeks ago - problem started shortly after.Â

I recently purchased a Mac Mini at the Apple store. I'm using an Apple bluetooth keyboard and trackpad. Problem is, when the mini goes to sleep, it won't wake back up. Nothing I can do apart from a hard restart by pressing the start button will wake the computer up. I don't know what to do to fix this. Is it something in settings?

I have an early 2008, 24-inch iMac. This problem started after I installed an OS X Mavericks update (and has continued). Basically, after the screen is asleep for a while, if you come back and move the mouse / tap the keyboard, the desktop never reappears. The screen stays black but the mouse cursor shows up and you can drag it around. I've seen some similar issues that said they could get the app switcher, but that never happens for me. Just mouse cursor and black screen, no matter how long you try to wait it out or tap buttons. The only solution is a cold restart, although I think in the past I was able to fix by turning off energy saver settings for putting the display to sleep. It doesn't happen every time, I'd say it happens over 50% of the time. The problem actually kicked in with one particular App Store update of Mavericks. I believe it was 10.9.3 if I recall correctly.

I have an Early 2008 Mac Pro with an ATI Radeon HD 2600 XT graphics card. Yesterday I could not get the display to wake from sleep in the morning, and even after a reboot I had nothing to look at. Then I (eventually) moved the card to another PCI Express slot and everything worked! Then after a reboot no video again. I moved the card back to slot one and it worked! Rebooted again, no display. Move card again, everything is fine.

I have an early 2011 MacBook Pro (2.0 GHz i7, 4 Gig Memory, Lion.7 with all upgrades) that has just started behaving strangely. When I put it to sleep by closing the lid and wake it up by opening the lid, the display is normal for a moment or two, then goes black. The keyboard is lit, and clicking on the trackpad gives me an alert sound, but it seems impossible to get the screen to light up. The only way I can get the screen back is to restart the computer. Putting it to sleep by clicking on sleep in the Apple menu works fine (it wakes up normally), but closing the lid doesn't.

I have a 17" MacBook Pro Early 2011. I have noticed some strange behavior when I am charging the laptop.Â
For whatever reason, when I close the lid and put the machine to sleep, no matter how long the machine has been asleep when I open the lid again the machine wakes up just fine and the login screen shows, and then the display goes right back to sleep. This is not the entire machine - just the display. To wake the display, I have to unplug the Magsafe adapter. The screen comes back immediately after doing this. Plugging the machine back in does not cause the laptop to go back to sleep.All updates have been performed (Software Update gives me no available updates), and other than this issue there are no other problems with the machine. To my immediate knowledge, I don't know when this started, though I do know that it has been intermittent for some time. I was hoping that the firmware updates that came a few weeks ago would fix the issue, but it seems to recently have gotten worse. I cannot pinpoint anything that would be causing this... and environmentally nothing has changed. The laptop is in near perfect condition from when I bought it, I keep it in a sleeve and a padded backpack when I'm not using it.. and unless I have something open that I am still working on I actually shut my laptop down whenever I'm not using it (living in Texas this is a habit I developed due to old laptops being damaged due to the heat build up in a trunk. I don't actually leave my MBP in the car though especially if it is hot out...)Â

I have noticed on my Macbook Pro purchased in September 2013 that the display will take a long time (~30sec) to awake from sleep. I can see the mouse pointer on the dark screen but the monitor will not wake. If I close the laptop, and open it, the screen will come back to life.Â

I have a MacBook Pro (13'', Early 2011) & iMac (21.5", Mid 2011) using a Thunderbolt Cable to Target Display. Everything was working find and I could Command F2 to Target Display as expected.However, about a week about this stopped working. Now when I try to Target Display the iMac goes to a Black screen (like it's switching to Target Display) and the MacBook Pro does nothing. The iMac will be at the Black screen until I Command F2 again (or disconnect the Thunderbolt Cable), then the iMac goes back to the normal display. I have tried another Thunderbolt cable with no luck. I have perform all software updates on both machines (now both running 10.7.3) and fixed Disk Permissions. I have also found that restarting my MacBook Pro allows this to function as excepected (Command F2, Blue Flashing Screen, Target Display on the iMac). However, this is not an ideal situation since having to restart my computer is time consuming. Â

So for the first time in over a year since I purchased it, my iMac crashed twice.The first time was this morning, i went to do something and the screen went black, and my secondary display got black and white lines. I had to restart. And the boot screen with the apple logo hung around for a while.
Then, later on the screen went whacky after trying to wake it from sleep (not full sleep just display sleep) and had a bunch of moving lines and then I couldn't see anything. So luckily I got a picture. After restart, it seems fine.I'll call apple care in the morning, but thought i'd try my luck here.

Just got a new Mac pro and installed an SSD as the boot drive. I was downloading some apple software updates and left the machine alone to download for an hour.Came back and it was asleep or hibernating (is there a difference?)At that point I clicked the mouse and I could hear it start back up but NOTHING came on the screen, just black.I could press a key on the keyboard and hear the error type noise so the desktop was active, just not being displayed.
I disconnected my mini display port (I have a 24' Apple cinema LED display) and plugged it into the second mini display port on the back and it came back on.Anyone know what this could be?A result of an SSD boot drive or do I need my LED display plugging into a particular mini display port out of the 2 on the graphics card?

I have a MacPro 1,1 (2006) 2.66GHz that it is always working as a home server. Â
After some time working idle the screen goes black. When I want to wake up there is no response. The screen turns into safe energy mode blinking his LED light power indication. I have to force shutting down pushing phisically the power button for some seconds. Â
Graphic Card problem? I have another one but I don't test it for now. Â Â
I have made a PRAM reset and SMC reset shutting down the MacPro, unplug the power and push the power button for 10 seconds. No results at all.Â
Even putting Energy System Preference on NEVER (computer sleep and screen) after some time (2-3hours) the MacPro goes to black screen.Â

I'm on Mac Pro os x 10.5.4 and having a problem with my computer waking up from sleep or as it is booting up.
As it wakes up from sleep, the screen becomes blank or shows weird, pixelated bars all over the screen. When I try to move the mouse or press something on keypad, the computer freezes after and I would have to force shutting it down by pressing the power. It doesn't always happen, but quite often these days.
Also, when it's booting up, it sometimes will freeze with a blank screen in the middle and won't show the desktop.
Everything worked fine until a few days ago, and i'm wondering what's suddenly causing this problem.

My screen on my 2 week old iMac comes up pixelated leaving square trails mimicking the movement of the mouse. I have had consultations twice with Apple support junior team members, looking forward to a senior team member reviewing my case. It looks like some sort of eraser wiping the blank dark screen revealing the login screen underneath.
Oh by the way my first iMac was sent back due to dead pixels, how unusual is that?

Having some trouble with my iMac (the version right before the intel iMacs came out. further info can be provided if needed). Running all the latest software updates etc. When I put the iMac to sleep, it goes off as normal. With the usual white light. However, when coming to wake the iMac it won't respond to the keyboard or mouse. I have to shut it down at the power button, and then turn it back on.
