MacBook :: Screen Intermittently Turning Itself Off And On / Sleep And Wake Occurring
Aug 8, 2010
I bought a new unibody Macbook around 4-5 months ago and I've generally been very impressed with it. It's my first Mac and considering all the problems I'd had before with Windows PC's, it's quite a relief.Anyway, here's the issue. When hooked up to my 24 inch Dell monitor there are numerous problems. Originally it just started with the screen intermittently turning itself off and on, and there being a sleep/wake issue. I did some research then and discovered that this was by no means a problem confined to me. Knowing this I was prepared to wait until Apple fixed it with a firmware update or something, as the problem was annoying but not devastating.
However since then the problem has got significantly worse. Not only are the screen flickering, sleep wake/issues occuring much more frequently, but there are other problems. For instance, the menu bar and the dock sometimes fail to show, and I've been having a very weird problem with the Logitech mouse I use. Even though I can move the cursor generally I can't click, and when I can, only the right mouse button works.The same is true with the trackpad, so it's not a problem with the mouse.
When these problems occur the system generally seems to be very slow. I've checked the 'activity monitor' and the use of 'system memory' seems to be very high. For instance, at the moment (I'm using my Macbook by itself) I'm running a few applications (Mail, iCal etc.) and I've got 1.09 gb of free memory. Last night I was running exactly the same applications and I must have had less than 0.4 gb of free memory. The pageout numbers were fairly high as well.
It's strange because when disconnected from the external monitor the Macbook seems to work seamlessly. I just don't understand how some of the problems I've experienced (such as the mouse issue) can arise from problems relating to the external monitor setup. What do you think? Should I be worried that these issues are perhaps indicative of a greater problem? Either way, the problems are becoming hard to deal with. Very disappointing.

I'm having a regular problem with my MacBook screen. Every time I put it to sleep, when it starts back up again the screen stays blank / black. The way to remedy this issue is to close the lid and open it again immediately. Then the screen comes on and no further problems.

It's a 2008 aluminum 13" MacBook with snow leopard 10.6.4

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.
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 trackpad
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.

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'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.

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?

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.
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.

Last week in the middle of my work day nothing special, the system started playing the camera shutter / screen capture. I started timing between the shutter, every 30 seconds, very annoying - the camera shutter sound - same as the shift-4 screen capture sound and same as the sound that occurs when you press the back button in terminal. I have a 15 inch mac book pro. 2009 model.
I wondered whether someone had installed a hidden shell script or apple script program and is capturing my screen and maybe sending it over the net. I don't know where to look or how to turn this off.
I have checked activity monitor and did not notice any programs running like "screencapture" or anything else like that. I have also turned hidden files visable on, but i can't find any screen capture directory or files: .jpg, .pdf, .png files I should be seeing lots of them for every 30 seconds per capture.
I have also installed little snitch, nothing strange seems to be going out by way of connections. Only dropbox, i have deleted that but the noise still keeps going. I will have to reinstall again..

Found this issue on many forums, but unfortunately I cannot find a solution. Taking to an apple store for repair is not an option. If I'm going to spend $300-$400 for repair, I might as well purchase a new PC. I am not that attached to this mac, and now with operating issues, I'm even less so. At least with a PC I can ctrl+alt-del and start all over. I was expecting more than 4 years out of a $1200 imac, so if I have to replace repair every few years, I'm thinking I'd rather start with a clean slate for $400 every few years with a new PC. Very frustrated not being able to find a solution online about this problem, seeing that it seems so common.
While working on imac and surfing the net, my screen will intermittently go to sleep. I can wiggle the mouse and click it and it will come back on right where I left off, internet connection and all. Once it happens, it continues to happen until I shut down and walk away for a good length of time (overnight). Problem seems to happen when the imac has been running for many hours at a time. I have set up the activity monitor, but I don't know what the numbers mean or what to look for.
This initially started happening this past summer, and I thought it was a heat issue, but now that it's happening mid-winter, not so sure. Also, in the summer this seemed to be prompted by streaming online, but now it is just from surfing. Not sure if it would shut down if I was working in Pages or Numbers, as I do so infrequently. Doesn't matter if it's Safari or Firefox and it's not a hot corners/sleep issue. Also noticed my fan runs loud sometimes, but not always. Not sure if it's a related problem. Does not sleep because of fan, no consistency in shutting down, etc.

Apologies if this has been posted before, but rather than trawling through the thousands of threads, and before hitting the Genius Bar.... thought I would run this by the experienced MBP owners first.Got my first MBP (crossed over from PC back in April), and within the last couple of weeks, noticed that the screen is flickering intermittently.
Wondered if it's a glitch stemming from the switch from Graphics card as/when needed, or if it's an indication of something more serious and warrants taking it in to the Genius Bar... (don't want to part with it for days unnecessarily).

I have a MacBook Pro 2.33 GHz Intel Core 2 Duo, running Tiger 10.4.11. It has an issue where it takes a LOT of tries (10 - 20 tries) to get it to start up. When I hit the power button, it will turn on, the hard drive spins, the fans go, the usb ports work (I had a laptop cooler hooked up to it that would spin when I turned the computer power on), BUT the screen stays black, no chime. If I keep trying, by holding the power button down for 10 seconds and then hitting it again, it will usually start up on the 10th or 15th or so try.
I've tried varying amounts of time between tries, five minutes, ten minutes, overnight, etc. I haven't done any recent software or hardware updates. Once the computer starts up, it works just fine, aside from running quite hot (typically 60+ sometimes up to 80+C when I'm running photoshop or illustrator).

I have a macbook pro (identifier MacBookPro 5,1) which I have been happily using for about 18 months, however recently the screen has been acting up. It will occasionally display lines one pixel wide, but over the whole screen (it's quite difficult to describe so I've attached a photo). This happens seemingly out of the blue, probably once every few hours of normal use, and the only way I've been able to get it to go away is to close the laptop, then open it again - Sometimes it only takes a few goes for this fix to work, sometimes a a lot.

My macbook, 3 years of age, always turns on whenever I put it into sleep mode. It gets REALLY annoying. So I close the lid, and a few seconds later, you hear the macbook turn on, then a few seconds later, it goes back to sleep mode. This happens endlessly and it gets really annoying.

I'm a Mac Pro guy and this is my first Mac laptop. How do I make it so nothing happens when I close the lid? Not using external display or anything. Sometimes it's just nice to be able to close the laptop when moving from place to place, I just don't see the need to sleep the machine when I do so. I do this on my Acer laptop all the time.

I put my 3 day old MBP to sleep last night with a 90% battery level (with the A/C adapter unplugged). I had calibrated the battery the day before. This morning, when I opened the lid, nothing happened. I thought this was odd. I then pressed the power button and heard about 1 second of the startup tone and then nothing. I repeated this twice more with the same result. I then plugged in the A/C adapter and the MBP booted up. The battery level was 86%. What do you think has caused this? Do I have a defective battery or something more serious?

However, twice now when I've run the battery down (as recommended to keep the battery healthy), and then put it to sleep and plug it in, when I try to wake it up later, it won't start. Powering on and off just lead to a little "click-whirr" and the power light pops on and off, but no action. I called applecare and they said to unplug it, take the battery out, leave it out for a bit, then put it back in, then plug it back in, and restart it. It worked (although the second such crash, it took two tries for unclear reasons). Needless to say, this is a bit frustrating. Is this a known problem? Should I do something to avoid it? Is it a lemon?

Everytime I sleep my MacBook for more than say 15 minutes, I start it back up, login, it works for about 20 seconds at which point it gets really slow, then I get the spinning color wheel and it doesn't stop spinning, forcing me to do a hard restart. I am running Leopard 10.5.2.
