MacBook :: Screen Randomly Turns Off?
Dec 5, 2010
At least, it seemingly randomly turns off. I can be surfing the web or whatever like normal, but then after a period of time the monitor goes black. I can see that the computer hasn't shut off, but it's as though the computer is on its lowest brightness setting. It can be temporarily fixed some times if I lower the brightness all the way via F1, then put it back up, but if it goes up more than 3 or 4 boxes it goes black again.
It also goes black if I were to move the monitor any time during this whole thing. I've heard things like an inverter cable and board, but I have no idea what's going to fix this. This is my only computer, I use it for all my school work, if it breaks permanently I'm screwed.

Anyone else noticing their new macbook air freezing randomly and the screen just turns completely black? The back light is still on but nothing is on the screen.
None of the buttons work, can't force quit anything, i have to hold power button to turn it off then back on.
It has happened to me twice already, first time when i was installing the adobe suite, second time is when I was working on a school assignment with a simulation app (not cpu or memory intensive AT ALL).

My Mac will freeze at random moments (not while running any particular app or program) and go to a blue screen, after a few seconds it clears up by itself. Sometimes it will happen several times in a row, sometimes 10 - 15 minutes in between.

This is a strange issue I have had with my Macbook Pro for a while now. Whenever I am in a situation where I am only using my computer for say, listening to music purposes, I like to turn the brightness all the way down. Whenever I turn the brightness all the way down, however, after a few minutes it will go back up 1 pip of brightness on its own. Once I come into contact with the trackpad, however, it goes back down. Then it will go back up 1 pip on it's own again, and go back down when I touch the trackpad. It continues to do this and it's quite annoying.

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.

lately, my mba has been behaving a little weirdly. its screen would suddenly become a little dimmer when the brightness in the room has not changed a bit. after a long while(15 min?), it'll turn brighter again by itself, and again without any change in the lighting of the room. the change is not big but obviously. any idea? can it be some software? or setting? or a defective light sensor?

I just bought a refurbished macbook pro and at first the screen wouldn't turn on when I started it up, the little sleep light was on though. I pressed and held down a key for a few seconds right after pressing the power button and the screen worked. My question is, should I be worried about this? I got the computer from a company I later found out is really difficult to deal with so I don't want to have to return or exchange it, but I also want to get my moneys worth.

I've installed OSX successfully many times but this one, with a new WD disk gives me trouble. After the gray screen is gone and the installation menu starts, the back-light turns off and I can't do anything about it. Any idea why that happens and how I can deal with it? I am working on a Mid 2009 13" Macbook pro with 2.26ghz and 8GB of RAM.

I can hear the chime going off, but the display turns on you cannot see through naked eye, you have flash light onto to the screen to see very little, can you tell me why this is happening and how to fix this issue. Secondly, can you tell me how to fix this issue, my keyboard and trackpad doesn't work. Is it the problem of flex cable of both the keyboard and trackpad or is the related to software

having problems with my MacBook Pro. Turns on, straight into user log in. Once password is entered it tries to start up then eventually after grey progress bar has finished brings up a grey screen, then shuts down again.
I've tried starting in safe mode and resetting PRAM etc with no success.

My screen is black but my laptop is not off.. and its not that only the screen is black, my mac on sleep (i think)...When I turn my mac on, it does turn on.. The starting screen comes out.. but the moment the desktop opens, the screen goes black. And if I try to wake my mac up by pressing any key, the mouse shows for like three seconds(on the black screen, not my desktop). So that means that my mac is not totally off, it's just that the screen is black. But once in a while, when I press any button, my desktop shows for five seconds and the screen turns black again. I had yesterday was that the finder was keep restarting. I was still able to go on all the apps except that I could not open any files on my desktop.

my MBP is really screwing up these days. Basically the best way I can describe it is that randomly once in awhile (no matter what I'm doing, usually surfing the net) the screen flickers a few times, then most of it turns black (except usually for a small part on top that stays on whatever it was displaying before). The section between the part that stayed the same and the bottom is sort of "multicolored".
The computer does not respond to anything except holding the power button down for 5 seconds until it shuts off. If I try to adjust brightness or sound level, nothing happens. Anyway, I took it in to apple and they claimed it was the motherboard, so they replaced it. But today I had the problem again! What else could it even be? Any chance its the RAM/screen/hard drive?

I bought a brand new Dell U2713H monitor (resolution is 2560px wide) so I had to get a dual link adaptor. I plug it into my Macbook pro 17-inch, Late 2011 and it works beautifully for about 10 minutes and suddenly the screen turns to static and i get a dvi symbol on top left. i then turn off and on the monitor and i get another 10 minutes. I was sure it was a faulty dual link cable - but i am trying the monitor on a macbook air and it is working perfectly.
perhaps the AMD Radeon HD 6770M 1024 MB card is not good enough? but i was told by apple support before i bought the monitor it is fine as long as i use the dual link cable.

I was using my MacBook this evening and navigated to a webpage that wouldn't load (perhaps due to excessive load) when my screen turned off and refused to turn back on. The white "sleep" light remained constant. I shut the screen and the light started to blink after the optical drive made it's noise and then I opened the screen again. The display turned on for a few seconds turning back off and the light on the front reverted to it's constant state.
I repeated pressing keys, the mouse and closing and opening the screen a few times before holding the power button down and forcing it to shut down. It's working fine now. I am wondering what caused this sudden behaviour though and how to best stop it from happening again, if I was working on something that needed to be saved, I'd be buggered. Perhaps it's an issue Apple needs to service, but how do I reproduce the effect then?
At the time I had a few applications open:
Mail
Safari
Mercury Messenger
iTunes (not playing)
Last.fm helper app (but no songs were currently playing)
I was thinking it could possibly be related to the Last.fm app, but why would it turn my screen off and then cause it to continue to not respond/turn off? Should I be looking in the Console for a log before shutting down tonight, would that reveal something?

I was reading a recipe the other night and my Macbook started ticking, the screen went black, then a white screen came up with a blinking envelope with a "?" in it. This happened once before when the computer was about a year old. I took it to the Apple store and they repaired it. The problem is that store is 2 hours from me. Does anyone know what this is and how to fix it? I have hit different keys and nothing takes me out of that screen. My biggest concern is my pictures and music are on it. I plan to buy another computer (anything but Apple) if I can't come up with a fix for this. Is there any way to get my music on my Iphone onto another computer?
