Possible solution to the black screen problem

My macbook air is 13-inch, 128GB
OS is os x 10.8.4
My problem is:
After closing the lid, the mac goes to sleep. And after a time which is longer than the value of standbydelay setting (to know what is standbydelay plz refer to https://developer.apple.com/library/mac/#documentation/Darwin/Reference/ManPages /man1/pmset.1.html), open the lid, then the screen goes black directly, no login screen, but the backside logo is lighting, the keyboard is lighting, and the screen has faint light, not complete dark.
My solution:
The following is useless or just temporal
1. Reset SMC or PRAM
2. Select startup disk
3. Reinstall OS X
4. Delete sleepimage file
The following method is not good, so i don't give it a try
pmset -a hibernatemode 0 (disable Safe Sleep, which can result in data loss)
The following is what I use and useful until now
Click System Preferences
Click Power Saver
Click Lock to lock it
Import plz Note: If u reboot it, u need to Lock it again. Because the system unlock it after a reboot or shutdown-start.
Apparently, it's another OS bug which is so ugly. Does apple have a test team?
Try it and check it for a few days
If it works, plz post it to let others and me know

Second day and no freeze from sleep.

Finally a SOLUTION for the black-screen problem!

It took me almost a MONTH to find a solution to this wide-spread problem - and I had to do it by myself.
I've got a Qosmio x300 (about 18 months old) and started having the black screen / lock-down problem about 6 months ago but it was sporadic. When it started getting worse, I took it in for repair, made sure it was cleaned religiously, had both a cooling pad and household fan directed at it to eliminate any possible overheating issue, made sure all of the *Toshiba* drivers were up to date according to their site, etc... The problem kept getting worse - to the point where I couldn't even open a browser without the dumb thing crashing. VERY frustrating to say the least.
Finally I gave up - I removed the nVidia driver that ran the GeForce 9700M GTS video card and used the standard VGA driver. No more lock downs, but it limited what I could do because the on-board memory wasn't being utilized. I re-installed the *Toshiba* drivers for the card and presto - lock-downs again.
Fed up, I went directly to the nVidia download page and chose to have it automatically detect my card. Now, granted, it says to try to use the OEM versions of graphics, but Toshiba's drivers are FLAWED! I installed the driver suggested directly from nVidia, and what do you know? Full use of the card again and not a single crash!
I hope all of my frustration, and the solution that resulted from it, can help someone else not have to waste time, money, and hair on their heads as it did with me. =) The sad part about it all - this is a TOSHIBA flaw that affects a wide range of systems and models - and nothing has or is being done about it.
Good luck! =)

Which version of the nVidia driver did you use?

Possible solution to the N97 screen freezing

Hi everyone,
I decided to open a nokia account to explain how i solved my troubles with the n97. First of all, sorry in advance if I don't write a correct english.
My user experience with N97 wasn't bad at all at the very beginning. When everybody seems to have problems, my firm 12 and 20 worked fine, no serious issues (however not perfect). It all begin a couple of months ago, my n97 didn't have the response i was use to. The screen didn't work, it was almost permanently freeze, as the menu key. I couldn't even switch off the alarm every morning and enter the pin was a hard work. The last couple of weeks i thought it had a hardware failure, but i've done several hard resets and mass memory formattings, and then it worked fine again, but only for a few minutes...And then I got it....It worked fine until i connected it to the Ovi Suite and some "help software" was automatically installed on the C: of my phone.
That is the point when my phone begins to have several performance issues. So I tried to unistall all this amount of software and my phone seems to work fine again. I don't remember the whole list of programs, i remember something like "Contacts DS group", "SMS DS..", "Controller service",etc... In fact I uninstalled everything I had in C: except "API Bridge" (The only program i had before connecting N97 to Ovi Suite).
I don't know if this is a general solution or if it's my solution to this kind of troubles, but if I can save the pain to somebody, this post has a point!
Thanks and greetings!
PD:By the way, if anybody from Nokia reads this: I see that lots and lots of people have problems of any kind, also, the phone has lack of RAM, lack of C: memory, even working fine the screen response is often annoying, in some areas the N95 was better, the loudspeaker is terrible, etc.... I think that a few apology words from the vice-president is not enough at all. If they HAVE BEEN PAID with all our money and the device is not by far what they claimed to be, and simply DOESN'T WORK, we need something else. Take responsability, you can sell a mistake, but then DO SOMETHING!!You can't DO NOTHING!Offer a discount on a new model, an exchange, whatever, use your brainstorming team!It would be a clever and polite hand played by nokia that customers would appreciate. I know that this is a way to acknowledge the failure of that device, but ...wouldn't be nice a little of honesty facing the evidence?

Second day and no freeze from sleep.

Can anyone tell me a solution for the freeze screen problems?

Mostly when I'm using the Internet and have various tabs opened, like you tube or online videos, the screen freeze and starts to fade and disappear till it goes white. During the process i can't move the mouse so I can shut down the computer properly. This also happens, but not as common as when using internet, when i turn on again the computer after having shut down with the power button, the only choice left when this happens.

you seem to be referring to an ongoing issue

How to How to install ATI Radeon HD2600 driver on bootcamp 3.0 windows 7 partition w/black screen problem

Ok....so i've posted this question in a different way, and i gotten several "scratch the surface" answers from people just saying to install "Ati catalyst", or insert the os x dvd and run set up.exe, and update to boot camp 3.1 or 3.2...while these all seem like great suggestions, I am finding myself needing more specific direction or "hand holding" so to speak.....here is the MAIN problem...
The Background/history
I used boot camp (3.0, and i found updates for 3.1 for imac and for windows, but can't find for mac pro, AND they all are ".exe" files which run on windows..which as you'll see is the big part of my problem...So I recently updated my mac pro (with the ATI Radeon HD2600 graphic PCIe card with 10.6.7 from 10.5.8. I created a single partitioned drive to install windows 7 professional 64 bit. The download software function didn't work (Thanks, APPLE for that poor level of support) so have to select the option that i have already downloaded, or have other media with the drivers already on it....i restarted with the windows 7 disk in....
The installation of Windows 7 Pro 64-bit
So the installation of windows 7 seemed to go flawlessly, was able to use my existing 23" hd apple cinema display (so somehow it has drivers that work with the graphics card, or maybe the motherboard's on board video components) and i select english, and install now, custom, blah, blah, blah...installation causes a few reboots, then restarts ultimately back in os x since that is the default boot os i use on this desk top and have to do the "opt" button to select booting in windows....so when i try restarting in windows, now using the actual boot drive on which i am installing it, it ran through another reboot or two, but then after that, my display goes black.... in the communities, the solution sounds super simple... "go download the ATI catalyst for the black screen problem....windows 7 doesn't have device drivers that work with the ATI radeon hd2600...no problem, just go download and install...."
The problem, re-emphasized : I cannot even finish the install for windows, because of this driver problem....i cannot see anything....I have tried to reboot in safe mode, and that then seems to invoke whatever basic drivers that do work, likely through the motherboards onboard video vs the actual graphic card, and the screen works and says that it's wanting to complete the installation, so i'm thinking awesome this is gonna work....and then.. "windows installation was not completed and cannot be completed in SAFE MODE, need to restart, blah, blah, blah" pops up...and forces reboot...so Safe Mode allows me to see, but won't allow me to finish the install of windows 7...and without completing the install i can't run (ranther I DONT KNOW HOW TO) any of the various .exe files everyone is telling me are the solutions to my problem...like update 3.1 and 3.2 bootcamp...they're all .exe files? not sure why, because bootcamp runs in 10.6.7 i thought, but whatever...it needs running Windows to execute...then the ATI radeon hd2600 driver for windows 7 that i downloaded from the site has an installation program that is an .exe file, which needs windows to run... Does this make sense, why i can't just use these fixes, that seem to be the only fixes out there....so can someone school me step by step here (not just the highlights) of how to update bootcamp, and how to install the ati radeon driver without having been able to complete the windows 7 installation because the monitor goes and stays black????
This is so very frustrating for the record...and any substantial help "not just go download this..." would be immensely appreciated.
Some other things i've been told to try that i've tried and nothing seems to happen as i'm told it will....
---I've been told to install the osx dvd and run "setup.exe" - AGAIN...it's an exe file...and 2 - when i put in the os x file it just wants to re install 10.6...so need more help if this is even a real solution to understand how to make it work...
---I've been told to update boot camp to 3.1 and/or 3.2 from 3.0, using Apple Software Update....Well, my software update is saying everything is up to date and there is nothing new to download at all, and when i reverify the bootcamp version it is still only 3.0.2...and again downloading the updates from www.apple.com/support/ for 3.1 and 3.2...all of those are .exe files...need windows to run them...again, refer to the problem described in detail above...
---I've been referred to the black screen on imac early 2011 thread saying it should fix my problem...and reading it it SEEMED like the most promising resolution...it involves creating a boot flash drive for windows 7 and an xml file that sets the imac drivers to auto install during the windows installation..and it got me farther than anything else..but still ultimately ended up in the darned black screen...my assumption is that it's because it's for imac and not mac pro so not ati-radeon specific drivers....ok....that's enough..please...anyone who thinks they can help...your help is desperately needed...thanks so much in advance!

hey Hatter, thanks so much for getting back...so just to be super clear...is there no way to install the drivers using an exe file given my current state? no way to do it with command prompt or something? if can make work with existing card, i'd prefer it...now when you say it's 'toast' how do you mean? it works well with the os x partitions and always has...so i'm not sure i follow, just want to be clear...
Now to your point of starting with only the one drive installed...so i would put that bootcamp drive in bay 1 and disconnect the rest...i'm not totally sure what you're suggesting the effect should be of doing this? just that i'm just installing windows without the bootcamp deal...but if windows 7 doesn't support the ati radeon hd2600, it still will go black screen no? or you're saying it will run video through the motherboard if it's the only bootdrive, and will run all the way through the windows install without trying to switch over to the hd2600? (slrry flr these questions..just really want to make sure i understand what you're telling me..thanks so much for your patience and help by the way...it's very greatly appreciated...your support is priceless!
So now, assuming none of the above is possible...referring now to the ati 5770 that you referred to...you mention it works with 10.6 well, and that windows 7 supports it ...2 questions on that
1) Windows 7 supports" meaning, out of the box windows 7 supports it? or will i have to install drivers still through some update, because again, if that's how i have to do it, then won't work, cuz can't start windows to see anything to install any drivers or run any thing at all...so it would have to just work with initial installation.
2)hardware wise for my Mac Pro 3,1...intel dual quad core xeon, blah blah....will this card work? it's a PCIe and should fit on my board no prob, etc?

Black Screen Problem on my Toshiba Portege M800-A330

I own a Toshiba Portege M800-A330 for more than a year now. Whenever I have problem on it, uhmm.. for example: virus, or corrupted operating system, all I do is to format my laptop or recover it using system recovery from the hard disk or using recovery disc which is inserted in the DVD drive. But, recently I'm having a problem with my laptop. My problem starts after I compressed the Drive C:, but I don't think that may cause the black screen problem that I'm encountering since then.
Here goes my problem: When turning on my laptop, the first thing I can see is the "TOSHIBA" logo and then after it fades it just gives me a black screen. I don't know why it's just black screen, perhaps its system has been corrupted. I've tried using the system recovery for the Nth times, but sadly the ability to run the system recovery from the hard disk partition also FAILED and just gives me a black screen again. When pressing "number 0" it does not direct me to the recovery features of the notebook but instead it only put me on a black screen. Likewise when I use the recovery disc, it also put me on a black screen upon entering in the DVD drive, and so as when I'm trying to reformat my laptop with Windows7.
I can't even access the safe mode options of my notebook. All I can access is the CMOS/BIOS setup features of the notebook when pressing F2.
Please help, I don't know what or where the problem maybe and what could be the possible solution on this. Any help is greatly appreciated.
Thank you,
Selene

I dont know how can i recover the the HD partition with vista installed.. do this mean I really have to send my laptop to Toshiba service center? It will cost a lot of money, my laptop's warranty already expired.
while i understand that the outlooking symptoms may appear the same, you report that you compressed your C drive but the poster in the linked thread does not... sadly, the underlying problem may or may not be the same even though the surface symtoms appear to be so...
unfortunately, i don't know what to recommend and i feel that i must leave further answers to other support members who have better knowledge than i :?
in my own case, i've finally determined that i must purchase the reload disks from toshiba and hope that they are able to restore my machine to the original factory condition... in you case, i can't say that this is the way to go or not... it really sounds like something either BIOS or OS oriented... since the BIOS reset didn't take care of the problem, it may be something deeper (ie: video broked) or something else...
have you tried booting a *nix live CD like ubuntu? the idea here is that if a live CD of another OS boots, then there may be something wrong with your HD...
along those lines, have you tried running memtest86+ and/or a HD testing util for the drive in your unit? it is possible that memory has gone uuck or the HD may have a section of bad sectors...
=================================================================================================================
I'm a user, just like you but i'm here on a volunteer basis without compensation from toshiba or anyone else... my crystal ball is in the repair shop and i cannot look over your shoulder to see what you are doing. the more specific you are, the better the answers can be

Black Screen problem on Acer Aspire 5733Z.

The screen on my aspire stays black on switch on. I am able to use a remote monitor. On the odd occassion whilst using the laptop the screen wil suddenly come on, but does not come on again following a switch off?? I have posted this problem before, but in attempting to thank a subscriber's answer using kudus the solution case resolved ticks showed in error. Therefore I still have the black screen problem. Have tried the suggestion of uninstalling adaptor with no success. Any further suggestion much appreciated.

Barnov,
One of the easiest ways to attempt to rule out a hardware problem........is to save all of your important files to a USB backup drive. And then reset your computer to factory condition. It can be a pain to do something like that, but it can save you hours of troubleshooting.
Your computer should have pre-installed Acer software that allows you to reset your PC. There's several videos on this website and also on Acer's YouTube channel that shows you all the different ways to reset your computer.
You should also make a USB recovery drive too. It shows you how to do that too.

Black screen problem and file size

Like others I have been having trouble with importing from iPhoto to iMovie. At times everything works just fine but on my most recent project I have been having a terrible time with the preview screen being black. I have used this discussion forum to try and resolve the problem. I've tried many of the recommedations but the problem continues.
In one thread it was mentioned that file size might have something to do with the problem. I think there may be something to this. I've noticed that any file that is 1MB or less shows just fine in the preview window. Files between 1-2 MB seem to have an erratic pattern of loading and files above 2 will hardly ever load.
Unfortunately I seem to have a lot of photos in the latter category (taken on a recent trip to New Zealand). I'm hoping someone can give me some hints on how to reduce the size of these files in a "batch" fashion. Perhaps via Photoshop?
Also, has anyone else noticed any connection between file size and the black screen problem.
Thanks.

Matti,
Thanks for the reply but that isn't the problem I'm having. I've read plenty about not emptying the trash and have not done that.
The problem I'm having happens before the picture is even put in the timeline. When I click on media, go to iphoto and highlight a picture that I want to place in the timeline I will get a black preview screen with the scrubber arrow running across the bottom. Through a rather tedious process I think I have determined that the problem is related to file size. If the jpeg file is greater than 3MB it will not load. Jpeg files under 1MB load wonderfully. Those between 1-2MB are erratic in whether they load or not.

I bought my Mac Air 13' in August. Black screen problems constantly happens. I asked some of my friends who also use Air. They share the same experience. Overall, it is a pretty good computer. But it bothers me when I do work and it suddenly goes black.

without more information, I assume you mean a blackout from sleep issue.
Go to system preferences > energy settings > raise the "turn display off" setting up to as needed, say 5 mins. or 10 mins.
AND ...
unchecked the "Put hard disks to sleep when possible" in both the battery and power adapter tabs.
test it and check back

What is the technical 'cause' of the infamous iMac black screen problem?

Can anybody shed some light on what technical malfunction exactly causes the infamous iMac black screen problem? The common solution seems to be a logic board replacement. But what exactly is broken on the logic board? Is it the Geforce chip? Some kind of external driver circuitry? Or something completely different?

I was referring to the many problems also described in this thread (and also in many other places):
http://discussions.apple.com/thread.jspa?threadID=196774&tstart=0
In specific I am referring to machines where all of this applies:
- internal monitor stays black after power-on
- computer boots normally
- external display works normally
- internal display backlight works and can be adjusted in brightness, but all pixels are black
- PRAM reset doesn't help
- NVRAM reset doesn't help
- PMU reset doesn't help
- reinstalling OS / booting from CD doesn't help
- machines with this problem sent to repair come back with a replaced logic board
I'm looking for more information on the technical cause of the exact problem as stated above. So I can attempt to repair my iMac

There is a problem on my mac mini. I install windows7 in my mac then i cancelled the installation did not finish..after that i saw the black screen on my monitor untill now the monitor is black..

It maybe trying to boot from the incomplete install.
Try starting your Mac while holding down the Option key, it should then list all the available boot drives including the Mac OS X one. Boot from the Mac one and then you can wipe the damaged PC one or set the Mac to stay booting in to OS X.

I'm sorry to learn that your phone is having problems starting up, marinema08. I'm sorry if this is incorrect, but are you using the original HTC Droid Incredible or a later Droid Incredible model? Please try placing your phone in Safe Mode to see if you are able to move past the Droid eye. http://vz.to/1kdQWVI If you are able to enable Safe Mode, please try deleting any recent applications you have added.

How to fix Imac 8.1 on Windows black screen problem?

Firstly when I originally got this machine it seemed (about 4 years ago), sometimes had my Pc forget the keys shortcuts for the Mac)
Anyway over the last year I have the problem where I'd be in the middle of doing something on the Windows side then randomly go black. Strangely this doesn't effect the Mac side on my Boot Camp.
After some testing on the Windows side I noticed this screen doesn't force the black screen when I'm either watching a video using 'Media player' or playing a game like 'STO' or 'KOTOR'. Also I wouldn't mind the black screen if it was temp but the thing is it stays black until I hard-reset the Imac.
Anyway does anyone have any idea's on how to fix this? It's been a problem for the Windows side for a while, haven't had much luck trying to fix the issue so the video playing 'idea' was always a temp solution till I can find a way to fix the issue. (The problems exists on both Windows 7/8 but now using windows 8 again because had to replace my broken hard drive recently).

Anyone else getting the BLACK screen of death after Kitkat 4.4 update?

Ever since the update, my phone is wacked, like everyone elses. I got my Samsung Galaxy S4 a month ago. Beautiful, loved it. Update happens: I want to pitch this thing as far as I can throw it.
The phone rings. I go to answer it but all I have is a BLACK SCREEN which is LOCKED. I have the lock on the screen, but if the screen is black, you can't see it - and you can't answer the phone! One day, I got a message, and could not get to that. Why? the BLACK SCREEN OF DEATH.
Someone told me to turn off Samsung Watch On and that has helped with some of the issues. But I still get the screen occasionally, and my battery life is GONE.
How do we get rid of this update? Should I just call Verizon and get a new phone with the OLD software? I hate this. I feel like I was the victim of bait and switch.

ltg123 - did you resolve the problem yet? If so, let me know how.
My (hopefully temporary) solution was to turn off my "Lock Screen" ... to do this, go to Settings, My Device, Lock Screen ... and select None.
The only issue is that you would no longer have any security for your phone and would be vulnerable to someone stealing your phone and having full access to whatever is on your phone that does not require a separate id and password. Dangerous, yes ... but, for me right now, it's better than not having any access to my own phone!
The Android update simply sucks ... some heads should roll for allowing such a crappy update to get (no pun intended) rolled out.
