Mac Pro :: Black Screen And Can't Wake Up Then
May 30, 2012
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

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?

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.

I slept my MacBook Pro last night and can't wake it? I have rebooted and no bing sound is made. The screen remains black. The volumn keys blip. It is as if it is still locked in sleep mode!

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

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.

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.

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 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 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.

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.

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.

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 Quad Core Mac Pro running Snow Leopard 10.6.4. I've been having this issue for the past couple of weeks. Basically I have my monitor set to turn off after after 15 minutes of inactivity, my Mac Pro is always on. After 5 minutes of inactivity my screensaver comes on and stays on until my monitor turns off. When I move my mouse to wake my monitor, sometimes an image from the screensaver appears onscreen for a few seconds and then disappears when my desktop appears.
I have repaired Permissions, rebuilt my drive using Disk Warrior, installed the 10.6.4 Combo update but the issue remains. An image from the screensaver doesn't always appear when I turn on my monitor, this issue is sort of random. Usually my desktop appears right away with no static image from the screensaver.

I have a MacBook Pro. Sometimes my macbook might fall asleep while opened, and when I try to wake it up it doesn't respond.. I can see the backlight on the keyboard light up but the screen isn't responsive? My only solution when this happens, is to restart my MBP.

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.

This has happened 2 times (rarely). Basically, when I wake up the macbook pro, the screen would remain "blank". I know the screen is on because I can see the mouse pointer but the whole screen is black. I'm assuming Finder has crashed?
I don't know how to restart on the macbook (ctrl + alt + del didn't work, using option didn't either) so I just held down the power button for 4 seconds and restarted that way.

i have had my macbook go to sleep an not fully wake up, the keyboard, cd drive wake an the screen would just turn the LED on, it brights up but does not show anything.i do NOT think its hardware, i believe the os is just not turining on the screen or speakers. it has done this 2 times an had to hardboot. before i hardboot it, i let it sit for a few minutes to see if it would wake up fully , an tried to close the lid again. also is there a short cut to restart or put it back to sleep so i dont have to hard boot. i dont expect to have this happen again , but if it does a key would be nice

This happens randomly. I don't know if it's the new hard drive I put in there, which I doubt.
The screen flickers from time to time (nVidia issue.) Don't have the time to take it in right now, but I will.

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.

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?

I am looking at purchasing an Ibook G4 but the description of the item includes this:"When you switch it on it begins to load up i.e. the blue screen with the Apple logo, but then the screen goes black or flickers. Said friend has kindly wiped the hard drive for me so now when you switch it on it makes the �opening� noise then you get a blue screen with alternating �?� and the Finder logo."
I have a feeling this may have been a temporary fault with the screen connector being loose and possibly damaged.But i assume the alternating "?" and the "finder logo" is simply a lack of OS?

I was trying to install Windows XP Pro, but for some reason the it wasn't showing another HDD to install Windows on. So I quit the install, and restarted my computer. Now all that happens is the normal grey screen appears (with no Apple logo), then it goes to a black screen and has the blinking cursor (Kinda like DOS).

So I have a DYNEX 21 inch HD TV conected up to my MBP via the VGA connection route. My problem is that when I want a program (or more specifically in this case a game) to go into fullscreen mode it automatically goes to my primary monitor and turns the other screen black. I know I can switch the primary monitor from my actual laptop screen to the TV however I just want the game to be full screen on the TV while still having access to my dock and everything on my laptop.
