I had this happen to me once because my cat walked on the keyboard and turned the brightness all the way down. None of the three solutions worked for me, but I found a solution for my case. I tried hooking up an external monitor and Windows 7 worked fine on the external monitor but still would not come up on the Macbook Air screen the screen also worked fine when running the Mac OS.

Using the external monitor, I searched around the control panel for the brightness control, and it was set all the way to the left. I moved it toward the middle and it worked. Note that you have to do this separately for both plugged in and not plugged in options. That solved the issue, but the brightness and volume keys still did not work. Not sure exactly how this happened, although my son turned the brightness way, way down using the keys in order to listen to something on my computer overnight, and this happened the next day.

May or may not be related, but I would guess yes. Hope this helps someone as I did not see this solution anywhere else and it took me several days of experimenting to find it. The third option for the black screen worked. Thank you so much for your assistance. I was in desperate need of the machine this weekend, and I had no time to return to an Apple Store.

Thanks again. Yes, the 3rd one worked for me, too. Twice now it has worked. Thanks for this great trick as it saved me money to send the Mac Pro back to Apple for no idea how long. Life saver! I tried all the other suggestions and the password reset kept popping up.

Thank you, This totally worked! Thank you! Thank heavens for generous people who share the solutions they find!!! I found a similar fix. Had someone call my phone — which is tied to my iCloud account on the laptop. As soon as they hung up, the screen turned back on. This seems like a stretch, but it did really work for me. I had tried many other things to no avail…. I had a black screen, but keyboard lit, caps lock light came on when pressed, and chimes. I tried everything PRam, reset, tapping spacebar etc. Then I reset the Apple password on another computer while looking for a solution.

I then wrapped the computer in a blanket like a baby for about 5 minutes while it was on. I opened the laptop, and was looking for another solution when suddenly it flickered and came on! The thing is last year work gave my husband an Iphone, which he logged into the icloud. They then took it back 2 months later. I tried all three suggested solutions, but the password reset kept popping up. I then clicked the shut down button, waited 15sec and rebooted the MacBook… It restarted as if nothing ever happened! OMG thank you so much!!!! I tried all of their suggestions and none worked but this totally did!!

Thank you Thank youThankyou!!! Many thanks. Probably will purchase the panel from ifixit to replace it myself. Thank you so much for the resolutions. The first option, reset the SMC, did the trick. Immediately it booted to a lighted screen. Thank you, thank you!!

The screen seems to be functional, but the backlight on the display is not lighting up. I can see that the computer is fully functional when I put a flashlight up to the display screen there is a fully operation LCD with no backlight. I have attached a peripheral display as a temporary fix and it works fine. I sent it out to the shop today with horror estimates that the entire display may need changing, or If I am lucky it may be a connector, a fuse, a capacitor, or a resistor that has gone bad or come loose on the logic board. I did not read this article until I had already sent it out to the shop, but I called the tech and told him to hold off on working on the problem until I can retrieve it and try these solutions..

My question to you is, do these resets commonly work when it is the backlight on the display that is not working, but the LCD is still functional except for the backlighting, and when plugged in, the peripheral display is fully operative? But I had to touch keys precisely. Many thanks! We tried all 3 options and others with no success even hooked up an external monitor. We were just ready to give up after a couple of days of trying. All of the sudden, without touching the keys, we looked over and the screen was working. Not sure why, but perhaps it had something to do with allowing it sit with no screen for several days.

Not sure. Has anyone else had this happen? Did you let it run or did you shut it down? After the second boot chime my mac brought up the white screen and password box. It then went to a loading screen and then into a black screen with my cursor for a while. After that it required me to log in again which brought up all my screens where I left them. Hey, I am a freshman in highschool and I have the most trouble with computers.

I thought I was going to have to buy her a new laptop.

PRAM worked for me!! Thank you so much, I have an exam in two days and all my notes had been on there. Any others ideas? Thank you, thank you!

PRAM worked for me, it keeped resetting for a few mins and it turned on out of nowhere. I had tried so many different websites and i was about to give up! The black screen happend 2 me 2. At first I tried all the above tricks to no avail. I have had my Macbook Pro for a few years now. This is the second time in the past few weeks that I have had this black screen issue.

The first time the SMC reset worked perfectly. The last time my screen went black, I had to try all three solutions several times, and finally the SMC reset worked. This makes me feel that there is something wrong with my Mac that needs repaired. I have never had this issue before a few weeks ago, and never on my previous Mac.

The article says that this is rare, but it has happened twice now recently. Would upgrading to El Capitan help? I held it down 8 seconds, and it should be done before seeing any light source in the display. So hopefully no more issues! Maybe a DC board problem? I had the same issue. I carry my laptop to and from each and connect via the display ports. One day, i walked away from workstation for an hour or so, came back and saw my laptop screen was black.

I figured it went to sleep, so i just closed the lid, packed it up and went home. When I got home, I opened up my laptop and did not get an image, just a black screen. After about an hour, of troubleshooting and reading forums Including this one , I figured the GPU died. I figured it was surely dead now. I got a hunch to reconnect it at my 2nd workstation, the one I had left it the night before, and bam. Picture came up on the retina! It was scrambled, very bad picture, but at least it was a start.

I disconnected and reconnected the display ports, but no luck. With the connections in, I closed the lid and reopened, but still no luck.

Restarted in Safe Mode press and hold Shift key while reboot computer until you get to Login screen and had my laptop connected to our TV using an HDMI cable so I could at least see if the computer was working, which it was, but just not my laptop display.

So I installed the update, restarted computer, and voila! Try this out as an option before taking it into an Apple Store. Hi thanks for this! The last option worked for my daughter after trying all the preceding solutions. Happened to me before on Yosemite with my Mac mini. Apparently I too, as a way of troubleshooting,opted to sleep the Mac followed by a forced shutdown and voila, back to business. Neither of these solutions worked for me. I would like to know if anyone has a another solution that has worked. Maybe you can check if booting an OSX installation pendrive, to see if the graphics start to work.

The display works just fine until the OS starts to boot then it goes to black with a white cursor immediately. Did you ever find a solution? Not sure if this caused the problem I had on the Macbook Pro but what worked like a charm was the first solution in this article. Connect to power outlet. The computer chimed and when it booted WaHoo, the screen was back. I did this connected to a secondary monitor so I could see what was happening. The laptop screen booted first, as usual. Thank you Will!

None of these. Worked for me at all: Any last suggestions? We are on vacation and I need to login for work! None of these worked for me at all: Try booting with an external display connected. Your inbuilt display may actually have failed. I had this issue with a white iBook a while back…. I am not sure if this is connected but prior to my initial upgrade the boot up to the log on screen took 25 seconds or so, with the password entered the main screen was a further 3 seconds.

After the upgrade it seemed to work the other war around, the log on screen was there in seconds, enter the password and it took 20 seconds to get to the home page, following the recent upgrade it has changed again, a black screen with the progress bar taking 15 to 20 seconds to get to the log on page, the password is entered and the home page is 2 seconds away.

I will try the suggestions posted above. I got the black screen but it booted normally otherwise. Black screen, white progress bar. I actually thought i looked cooler than the normal boot. If it works, leave it alone. Since the upgrade to YOSe and second ed, nothing bad has happened apart from the odd sudden shutdown during web surf … otherwise stable during heavy editing on iMovie brilliant new version for me… always found FCP a tad OTP for my professional needs and chuffed with all other apps in use… well done guys for the constant upgrades and as usual user friendly improvements …… Maje.

This is now a frequent problem for users of Mavericks and Yosemite, I tried everything with my Macbook Pro but nothing worked.

Even reloading Yosemite using one of the recovery tricks. Finally I decided to Pay for Apple Support and was pleasantly surprised to find that there is no charge for help with this problem on these two operating systems. The first technician took me through all the things I had done, trying to boot into Safe Mode, trying to boot into Recovery Mode even getting to the failure point and entering my password in case it was just hidden. He then got a senior tech on the line and she said she could fix this in 10 mins as it was a known issue. She had me power on and hold down the command and S keys.

Keep holding the keys until the screen fills with a lot of Dos like code. At this point she dictated 3 lines of text with things like plst and library etc, sorry I cannot remember much of it. Then we powered on and off and again the screen went black but she told me to just keep hitting a few random keys and lo and behold the system came back up and is now OK. The problem as I understand it is a corruption in some plist logon type files which she had me delete and on the next boot the Mac rebuilds them correctly.

Good Hunting! I am reading through my error logs, and I am seeing this same plist error. I just do not know how to fix it. Guess I will call Apple and hope that somebody there gives 2 chits enough to help me fix it properly this time! Thanks for the post! Thanks for the suggestions, but none of these methods have helped.

I decided to do a new clean installation of Yosemite and then restore my userdata. Everything went fine and I was happy with my newly installed MBA until a couple of days ago.

You are my life savor!! The only result that worked for me after searching all thru YouTube and Google for help! Thanks Jeszica!! You Rock! After trying all other suggestions as they come, yours work like a charm. Just had a customer who had this issue, turned on the MBP The flashlight on the screen in a dark room reveled the login page as others sites have stated, once I entered the new password I created on other attempts to fix the issue I was directed to the Keychain page where I entered the orignal password in the update Keychain password supplied by the customer and viola, straight back in and restarting as per normal.

No other issues and the laptop screen lights up as usual on startup and sometime when taken out of sleep mode but goes dark again within minutes. Tried all of the resets, no go. Any other suggestions out there?! Thanks OSXDaily! There are a few factors to the problem listed above, and the solutions for each of those should definitely be tried at least three times.

I was panicking when none of the solutions worked, and then I realized my MacBook was severely overheated. Nearly scalded my hands holding it. I started it up, removed all peripherals, put it to sleep clamshell mode and left it on the floor for 5 minutes cos all the cool air-conditioning made the floor really cold. Then when I picked it up again after it was all cooled, the screen just… worked. No flaws. Here are some points to consider:. Turn it off, or turn it on and put it to sleep. Apply something cold not ice please, more like blow at it with a fan or something to the bottom of the MacBook.

Again, check your MacBook and take care of it. Try all of these at once when your MacBook is at optimal working temperature. Then schedule a day to bring it to an authorized Apple Service Provider.

A Solution for MacBook Pro Booting to a Black Screen

Yes, it got that bad…. But I learnt to understand and fix this MacBook on my own. Surely, prevention is better than cure. This aluminium unibody does a horrible job at ventilation. So the air comes out from the keyboard, apart from the exhaust in the joint. Keyboard covers are the one-way ticket to suffocating your Mac.

Way to go Apple, sacrificing so much for aesthetics. This happened to me today. I went to the Apple store and they had a two hour wait. I was so tempted to just toss the computer in the trash. I got on my iPhone and found this solution. Works fine now. The second sequence worked for me. Thank you very much for the the. So here it is, and from the bottom of my heart: Same issue, took me a few days to resolve.

Try this sequence, stopping whenever you get the white screen and chime to display upon boot up. Get it back to grey screen and follow these instructions: Repair until you get the OK, then go back into disk utility apps repair and run it in there a few times. It worked for me, I doubted it but it did. Once i just smashed my keyboard after a few hours and that somehow worked too… do not suggest that last one. Upon getting it to load, have a hard drive ready and start grabbing the important stuff. Best of luck. I tried rebooting with option command p r and it made the chime.

Any suggestions? Hi- have tried all and this is not working for me. My MacBook pro was purchased in so very old. It starts but black screen. I have tried all suggestions above.

Omg thank you so much Jessica it finally worked for me! Unusual to have problems with Mac!! Obviously a fault with the Apple software!! Thank you Jeszica!! I tried all suggestions and nothing worked until I pressed power and then held option, command, P,R until the power sound came on about 3 times and then finally the screen restored.

Had to get a torch to shine it at the screen though to get through the secure login! What is previously black becomes just about visible. It worked!!! I refer to the original suggestion of control option shift power button, followed by normal press of power button.

Lately it just kills itself to black. Many thanks, especially as am about to go on a work trip and need my computer! Rebooting the PRAM worked for me! Thanks guys! I was wondering what the heck as my Macbook Air is only two days old!! Thanks again! I was wondering what happened to my Macbook Pro is only 15 days old!!

The tech said the code just sets your computer to find the last working startup. Hopefully it will continue to work: Good Luck! Mischa, Thank you so much! Your code here just got me my computer back!!! I had a black screen and could see pointer, but that was it. I followed your instructions and bam, the login screen came up!!! So excited!! The above method worked for me.

Nothing worked. I even reinstalled Yosemite from the recovery option twice and nothing. But this last option worked. Thank you a million.

Nothing had worked and was loosing hope until I found your post. Thanks a ton. After fiddling with brightness had that issue before I found this article and tried 3 solutions one after the other. Thank you so very much I went through all three of the props that was display and the last one worked appreciate you a great deal.

I had the same thing happen and tried all the steps, 1. Still, black screen. Black screen. Still the black screen. Still black screen. Back to recovery mode, reinstalled mavericks. Still, no success. In conclusion, I have tried everything but the apple service, the black screen arrived out of nothing and remains here, tormenting me.

Ok, so as I said, non of the 7 solutions above worked for me, here is what did: I found this solution on another troubleshooting forum which dealt with the same problem. Here are the steps that brought me back everything exactly how I left it: Turn off your Mac by pressing the power button until your Mac shuts down.

Reader B. That gap caused periodic screen blackouts. Pressing on the affected spot could restore light temporarily. While he replaced the screen, the problem came back. Waking it would re-activate the backlighting, at least temporarily. Running it with a dimmer setting for screen brightness also worked. Tye found that an Epson printer that used Wi-Fi for network connections appeared to cause an iMac blackout.
