Cannot wake up after screen goes black occasionally since update to maverick

Cannot wake up after screen goes black occasionally since update to maverick. I have to wait a few mintues and press power button to restart. Any one has similar issue?

I've found the problem!!
Mavericks for some reason overheats the GPU.
I downloaded a free 3 day trial of Temperature Gauge Pro http://www.tunabellysoftware.com/tgpro/
It showed a GPU 0 diode temperature of 122 degrres C. I think that's about 250 degrees Farenhiet. Insanely hot. No wonder the poor thing was crapping out. TGP alows fan control and so I set them to maximum and watched the temp come down quickly.
After all these months of frustration it turned out to be a simple fix. So I bought the program for $10. Sure a lot cheaper than having the Apple Experts replace a GPU or CPU like some have sugested.
What I still can't figure out is why Apple won't fix the problem from thier end and just update the fan parameters on Mavericks.

Screen goes black occasionally when using

When I am using Ipad 2 The screen goes black, an apple soon appears, about 3 minutes ,
Later the slider appears and I can open. I have tried resetting , but it always returns,

What are you doing when you get the black screen? Any particular app or game or site? Any commonality with crashes can lead to an idea of what is messing with your device.

Screen freezing/blacking out since update

Since the 1.0.1 update my phone is freezing sometimes. It froze a couple days ago right the middle of setting a wallpaper. I had to reboot it. Then yesterday the screen went black for about three seconds for no apparent reason. My phone was in sleep mode so I hit the home key. Then before I had a chance to unlock with the slider, my screen went black. Then a few seconds later it came back.
Never had this happen before. Anyone else having these kind of freezes or blackouts?

If the iphone starts to freeze the best thing to do is to power down the iphone.
It sounds like that is what you were trying to do.
If the freezing continues to happen, you might want to restore the iphone.
If you decide to restore the iphone, this article from he apple support website will help.

Iphone G3 screen goes black after ending every call.

My iphone screen goes black after ending a call. Shouldn't I have to hit the "end call" button? I'm having to re-boot the phone after every call I make. Anyone else have similar issues?

Nathan C.,
I know that and it is not the problem nor an explanation.
Here is the issue I am referring to:
When someone calls, still during the conversation when I remove the phone from my ear (in order to access the key pad, for example), or in order to hand up, the screen goes black and the phone freezes.
In other words I cannot terminate the call or access the keys,as I remove the phone away from my ear it shuts down.
Any help???

Cannot view movie, screen goes black

Download movies from itunes (usually with difficulty...doesn't seem to want to transfer on 1st or more tries). Once I get the movie, the screen goes black part way through viewing. At this point, video folder also shows a black screen. Took ipad back to apple store, they were not sure what to do so gave me new ipad. Same problems. Is it my itunes account that is a problem? Is it a bad ipad cable? I can sync music and apps easily...am I doing something wrong? (movies are HD-SD and no warning comes up that they cannot be viewed on ipad).

I read your other post as well that was directed to me ...
"Question to Demo....I have same problem and tried your suggestions. Instead of black screen when I open Video folder or by searching for movie name, I get small white text at top of black screen and searching circle in middle of screen...this disappears after approximately 5 seconds. No movie."
I have no idea what the small white text might be, but in your post above you mention that moving the movies from the computer into the iPad has been difficult and/ or problematic, so I suspect that the problem with the movies has something to do with that scenario.
I don't believe that the problem lies within the cable if you can sync and transfer other content. You could try another cable if you have one and see if that helps.
Do you by any chance live in the U.S.? If you do, movies (most movies that is) can be downloaded again at no charge as long as you use the same Apple ID that you both them with. So my suggestion would be to delete the movie from the iPad and download it again - but download it directly on the device and not use iTunes at all.
If you are in the U.S. you can go to iTunes on the iPad and tap on the purchased tab. Then tap the "View" button in the upper left corner and bring up "Movies". If your purchased movie is in there, delete it from your iPad and download it again. You can delete the movie by going to Settings>General>Usage>Storage>Videos and then swipe across the movie to bring up the delete button. Then go to iTunes and download it again.
You should not have to use another media player in order to play the movies from iTunes.

Re: Satellite Pro A200 - Screen goes black after BIOS screen

Hi,
I'm new to the forum and have quite a big problem. So any help is welcome and appreciated.
My Satellite Pro A200 goes black after the BIOS screen and a black screen with a blinking cursor. Also just before the screen goes black a bleep can be heard which shows windows is booting.
I can access the toshiba set-up screen but not the safety mode set-up.
Kind Regards

Hello
You wrote that you can access the BIOS but have you checked if the HDD is recognized properly? Maybe the computer cannot boot because HDD isnt recognized so you should check this.
If the HDD is recognized I would try a recovery installation from Toshiba recovery disk. It seems that Windows isnt able to start and if you reinstall the whole system it should help to get rid of this. Just go in boot menu and select CD/DVD drive as boot device.
Check this!!!

My 3rd generation ipad even though my battery is at 100 % the screen goes black after sitting for more than 15 mins. The only way to get it to come is by resetting the ipad. Is there a fix for this. It all started after the last two updates.

Screen Goes Black During Startup (after login)

Hello,
I have a 2005 Mac Mini PPC OS 10.4.11. This is the first problem I've had since purchasing the computer. This problem popped up out of nowhere. The screen goes black during startup just after I login into my account. I can hear the hard drive spin like it is finishing the startup process. The monitor power button blinks green.
I'm using the digital video cable. I tried switching to the VGA cable but the screen then goes black before the login screen.
The computer will startup in Safe mode.
I've tried Disk Utility (repair disk and repair permissions), Techtool Pro, Drive Genius, ColorSync Utility, Reset Pram, installed latest OS updates, and even re-installed the System twice (once because I removed all the Extension files and then the computer would not startup at all).
I've also tried removing cache files, plist files, startup files, preference files, and some or all of extension files.
The only applications I have recently installed were QuickTime Pro and a .flv movie player; both about a week before this problem started. I tried to uninstall them but could not figure out how.
What is the problem? How can this be fixed?
Thanks.
Richard

Howdy. I have Had the same problem as you in regards to a ViewSonic Monitor and the Mac Mini. This is my post:
Monitor failure when switching resolutions
Using Displays with the Mac mini, Apr 1, 2008, Replies: 2
Running 10.5.2 on Mac Mini G4 1.42 Ghz with ATI Radeon 9200, 32 MB VRAM and ViewSonic VX922
When switching resolutions from 1280x1024 to 800x600 or vice versa, the monitor will cut to black and the power light on the monitor switches from solid green to flashing green. Only by combinations of powering down the mini and starting it up again with the monitor on or off will bring the monitor back to life. This problem makes it difficult to play World of Warcraft amongst other games. Any feedback in regards to this problem would be appreciated.
Thank You!
At this point, I am unable to switch Monitor resolutions. If I do, the monitor goes black, and I have to power everything down and wait a while before I can restart.
I've resigned myself to not switching resolutions, but I'm wondering if you've had any luck.
Thanks for your time!

Windows 7 boot camp screen goes black after windows startup screen!!!!!!

A few days ago when I tried to start my MacBook Pro in windows 7 (enterprise) I encountered a completly black screen after the startup screen.
1) Choose start in Windows 7 from boot camp menu (holding option after starting up computer)
2) Windows start up screen would appear and finish
3) For a very brief second my cursor pointer would appear and login screen would flash onto the screen, then the screen would go black
BUT
I CAN boot windows 7 in safe mode
The computer is still on when screen goes black (fan still running and i can use keyboard commands to shut down the computer)
I've been searching the Internet for DAYS to no avail
PLEASE someone help me....... ive already tried the sfc /scannow and dskchk commands in the command prompt window

Win 7 Enterprise is not supported by Boot Camp, you may or may not get it to work reliably, (I would not bother to try)
Read this document then pick a supported version of Windows for your Mac.

I havent had the exact same problem as you but I am having a similar problem where lately I noticed when working in Pro Tools (mainly because I use my mac pro for audio work) or even when on the internet whatever it may be that my screen has been flickering a little bit or gets slightly glitchy.
Yesterday upon startup for the first time the screen went black. Had to do a force shutdown. Unplugged all external devices. Reset everything as well. Slowly checked everything was on the phone with Apple even during the process. Seemed to correct the issue. Then of course I get off the phone, restarted my computer and it goes black randomly again.
Rebooted fine. Checked all my hard disks internal and external, verified and repaired permissions on main drive and clone. Since then nothing yet...But I still feel its either the Video Card or the Monitor as everything else is fully operational.
I plan on taking it in to look at as my applecare is up in November but I cant point my finger on it. And really am trying to avoid lugging the mac pro and monitor in at the same time...(Not the easiest thing with lack of parking in nyc..)
If the display was dying I feel like it would have konked out already.
The funny thing is I have had to replace video cards and monitors in the past but this time I cant quite figure out what the **** is going on.
I am leaning towards the video card as I noticed it flickered a little when opening plug in windows in pro tools or multiple windows in sfari but it doesnt make sense.
Worst part is I cant do a hardware test cause for some reason this computer doesnt have the software installed. It does nothing when I hold down the D button...
I totally baffled but the randomness of this.

IMac screen goes black after 1+ hours of use and we can't get out of this.

I have a mid-2007 iMac. When anyone is on the computer for approximately 1-1.5 hours, the screen goes black and we cannot get out of this. There are no time restrictions or power-saver settings on. Can anyone help me with this issue?

You cannot do anything with the iPad until you do as instructed by the iPad and connect to iTunes on a computer.
You probably need to restore the iPad and the only way to do that is via iTunes on a computer.
Take it to an Apple Store and ask for help at a Genius bar or take it to a friend's house that is running iTunes on their computer and try to restore it.
You will lose all of your data and settings now because you never backed the iPad up in the past.

Screen goes black, shut the lid for a few minutes, open the lid the turn on chime comes on and the screen comes back to life. The computer itself has continued to update just no screen. After a few minutes goes black again. Is logic board going bad?

Screen goes black, shut the lid for a few minutes, open the lid the turn on chime comes on and the screen comes back to life. The computer itself has continued to update just no screen. After a few minutes goes black again. Is logic board going bad or graphic card issue? Trying to decide if computer is worth repairing as it was made in 2007.

It does sound like you might have a faulty video connection. See if you can make a Genius Bar appointment at your local Apple Store.

Why My Screen goes BLACK after gaming????

*My Screen goes BLACK after gaming, or exiting Full Screen Mode*. The music keeps playing, but doesnt do anythin! It only shows the mouse pointer so i have to force shutdown. how can i see my desktop and windows??? And it isnt the batteries. Help me thks

I suspect that your game has a bug when switching between full-screen and window mode. When or if this happens again while you are still seeing the black screen press the following three keys: option, command, escape (hold down all three at the same time). You may or may not then see the "Force Quit" window. In any case, release the optioncommandescape key sequence and press the return key. This should quit the game and return you to your normal desktop. You may have to perform the "Force Quit" more than once, two or three times being the most I would expect (that is, if the first time doesn't work).

Things you may want to try as well. When you start your computer move the angle of the screen and see if it still has the problem. If the problem goes away you are looking at a cable or connection issue.
If the problem stays the same then you may be looking at a driver or motherboard issue.
