• OSX Update 10.11.3 iMacs causes gray screen of death Mid 2011

  Hello everyone,

  I'm new to the forums of apple, so I don't know exactly if it was to go to the right place. This isn't any question that it's a PUBLIC service announcement.

  Basically, a summary of my post is that OSX update 10.11.3 causes both 27 "& 21.5" mid 2011 iMacs is not start properly. After the update installs and the iMac restarts, the startup sequence seems fine, showing the Apple logo, then the progress bar. However, when you expect your login screen to appear, instead you are greeted with a dark gray screen and movable mouse... and he the system is still a little sensitive. If you press the keys on the keyboard you hear the sound of "bum" as if you had to press a key when you weren't supposed to, and if you press the power button (do not want) the system will switch to standby (and wakes up if you press it again). So this isn't really frozen, it's just nice... it.

  Puzzled, I went to Google, hoping to find someone with a similar problem. I have not found much. I found some people with similar problems (gray screen is a bit more general), but I have found others with 27 "mid 2011 iMacs have this problem (links below :))

  Cannot install the update of El Capitan 10.11.3 (Stuck in gray screen)

  iMac mid 2011, gray screen of death!

  gray screen with the pointer to the login screen

  What I read, some iMacs have been recalled for the failures of graphics card, and that's what some people have responded to in the positions as a possible cause. (This is also what comes mainly from back when you search for "27" iMac screen gray) But this doesn't seem to be the issue here. The above posts are fairly recent and seem to coincide with the update 10.11.3 put in place, and they are the same symptoms that I have experience, but with no working solution.

  Once I have restore my backup time machine last before updating 10.11.3 is installed, the system works perfectly. Unfortunately, if you have not a backup time machine to restore, it seems that reinstall OS x is your only solution (until you reinstall the update)

  I'm not an expert of OSX, but I tried everything under the Sun to try to get the system to boot properly again, like resetting the PRAM & SMC , single-user mode, safe mode, none of this works. The system does not just start.

  I don't know if this has affected everyone with mid 2011 iMacs, but I just thought I'd let people with iMacs 2011 who are having problems with this update that you are not alone, and I hope that someone at apple can be seen. If you have an iMac 2011 that has not been updated to 10.11.3 again, I will not do.

  Thank you

  It is not material, it's software.

  My keyboard came with my Imac aluminum had a problem that I thought was material, but order the update of the post 10.11.2 v works again.

  Simply click near the center of the screen when it is grey and type your password.

• Only get a gray screen after upgrade of El Capitan. What can I do?

  I tried to install an upgrade, but only now have a gray screen.  The installation seems to have stopped half way through.

  Please take each of these steps that you have not already tried it. Some of them are not applicable to your model or your situation. Stop when the problem is resolved.

  To restart a computer is not responding, press and hold the power button for a few seconds until the unit turns off, then release, wait a few seconds and press again briefly.

  Step 1

  The first step to respond to a startup failure is to secure data. If you want to keep the contents of the boot drive and you have not already at least a current backup, you should try to back up now, before we do anything else. It may or may not be possible. If you don't care the data changed since the last backup, you can skip this step.

  There are several ways to back up a Mac that is unable to boot. You need an external hard drive to store backup data.

  a. starting the partition recovery or an hour Local Machine backup volume (button option key at startup). When the OS X Utilities appears, launch disk utility and follow the instructions in this article to support. You'll be 'restoration' the boot on the backup volume volume.

  (b) If step 1 fails due to disk errors, and no other Mac is available, then you may be able to save some of your files by copying them in the Finder. If you already have an external hard drive with OS X installed, the start of it. Otherwise, if you have access to the Internet, follow the instructions on this page to prepare the external hard drive and install OS X on it. You will use the installation program of recovery, rather than download it from the App Store.

  c. If you have access to a Mac, and it work and have both the non-working Mac FireWire ports or stroke, start the Mac non-working in target disk mode. Work Mac to copy the data to another drive. This technique will not work with USB, Ethernet, Wi - Fi or Bluetooth.

  d. If the internal drive of the non-working Mac is replaceable by the user, remove it and climb into a docking station that is pregnant or an external drive. Use another Mac to copy the data.

  Step 2

  If you have booted from an external drive, make sure that the internal boot volume is selected in the pane of the system preferences Startup disk.

  Start in safe mode. Note: If FileVault is enabled in OS X 10.9 or an earlier version, or if a firmware password is defined, or if the boot volume is a software RAID, you can not do this. If you do not see the words "Safe Boot" in the start screen, you did not start in safe mode. Ask for additional instructions.

  Safe mode is much slower to boot and run as normal, and some things don't work at all, including the networks without wire on some Macs.

  The login screen is displayed even if you normally connect automatically. You must know the password for the connection to connect. If you have forgotten the password, you will have to reset it before you begin.

  If the startup progress bar gets stuck for more than a few minutes, or the system stops automatically when the progress bar appears, the boot volume is corrupted and the player is probably defective. In this case, go to step 9. If you have another problem with the player, replace it immediately.

  If you can start and log in in safe mode, empty the trash and then open the window of info on the boot volume ("Macintosh HD", unless you have given it a different name.) Make sure you have at least 9 GB of space available, as shown in the window. If you do not, copy as many files as necessary on another volume (not another folder on the same volume) and delete the originals. Deletion is not complete until you empty the trash again. This, until the space is more than 9 GB. Then restart as usual (i.e., not in safe mode.)

  If the boot process hangs again, the problem is probably caused by third-party software you have installed. Ask for additional instructions.

  Step 3

  If the startup process stops at a gray screen together with a mobile cursor, then the logon dialog box may be active but not visible because of a bug. You may be able to connect by using the arrow keys or the cursor to select the password field and type your password as usual.

  Step 4

  Case of failure of step 3, the boot volume can be complete. If you saw previously implemented guard space drive is low, it is certainly the case. You might be able to start in safe mode , even if you cannot boot normally. Otherwise, boot from an external hard drive, or well technology for step 1b, 1 c or 1 d allows to mount the internal drive and delete some files. According to the documentation from Apple, you need at least 9 GB of free space on the boot (as shown in the Infolog) for normal operation volume.

  Step 5

  If a Mac desktop (without the built-in keyboard) crashes on a gray screen together with a mobile cursor, the keyboard may not be recognized. Hold down the button on the side of a wireless Apple keyboard to make it discoverable. If need be, replace or recharge the batteries. If you use a USB keyboard connected to a hub, connect it to a built-in port.

  Step 6

  Sometimes, a startup failure can be solved by resetting the NVRAM.

  Step 7

  If there is an integrated optical drive, a disk may be stuck in there. Follow these instructions to remove it.

  Step 8

  Press and hold the power button until the unit turns off. Disconnect all devices wired except those needed to start and remove all aftermarket expansion cards. Use another keyboard and/or mouse, if these devices are wired. If you can start now, one of the devices that you disconnected, or a combination of both, the origin of the problem. Discover that it is a process of elimination.

  Step 9

  Launch the utility disk in recovery mode (see step 1). Select the boot volume, and then run the repair disk. If problems are found, repeat until that clear. If disk utility reports that the volume is not repairable, the drive is defective and must be replaced. You can choose to tolerate such malfunction in the reader's life. In this case, delete the volume and restore it from a backup. If the same thing happens again, replace the drive immediately.

  It is one of the rare situations where you must also run repair permissions, ignoring the erroneous warnings, that it can produce. Look for the line "Permissions repair complete" at the end of the output. Then restart as usual.

  Step 10

  If the boot device is an aftermarket SSD, it may have an update and/or a forced "garbage collection". Instructions how to do this with a Crucial SSD of brand have been posted here. Some of these instructions may apply to other brands of SSDS, but you should check with the technical support of the provider.

  Step 11

  Reinstall the OS. If the Mac has upgraded an earlier version of Mac OS X, you need the Apple ID and password used to upgrade.

  Step 12

  Do as in step 11, but this time clear the disk utility boot volume before installing. The system should automatically restart in The Migration Wizard. Follow the prompts to transfer data from one Time Machine or another backup.

  Step 13

  This step applies only to models that have a battery logic-board ("PRAM"): all of the Mac Pro, MacBook with a removable main battery and a few others (models not updated). A flat battery logic-board may cause a boot failure. In general the failure will be preceded by the loss of the system and boot disk clock settings. Refer to the user manual for replacement instructions. You may need to take the machine to a provider of services to have to replace the battery.

  Step 14

  If you get this far, you probably deal a hardware failure. An appointment of 'Genius' to an Apple Store, or select another authorized service provider.

• Gray screen after update

  It gets frustrating after each update all the getting is a gray screen when the Apple appears, any suggestions

  Try running in Mode without failure.

• Black screen after start - "Video_tdr_failure atikmpag.sys.

  Original title: black screen after startup

  A few days ago I accidentally dropped my laptop I was trying to pick it up. It froze and I used the power button to stop it. The next day, it worked very well, I played a game, but then the screen got all blurry and it froze again. Therefore, whenever I started it normally, I would get a blank screen. But in Safe Mode, it worked fine.

  I assumed it was my hard drive, I got a new and it seemed to work very well, I had reinstalled W7. Until I tried to install the updates and it the screen went white again. I used the system restore and got it to do work. Then decided to move to W10.

  After the upgrade, the pc restarted with a white screen, I have it connected to the TV with an hdmi cable while you try to start it, then the screen worked fine. He stayed very well until I tried to install the updates. It would not just start up. He gave to the page «Video_tdr_failure atikmpag.sys»

  I returned to Windows 7 and now it always starts with a blank screen.

  * the screen works very well throughout the boot process

  And works fine in Safe Mode *.

  Chances are, at least (if not more) there is now a default in the video circuits.

  Be aware, the laptops are very delicate animals.  This type of accident will most often mean end of system life.  The biggest problem is the cost of the repairs in such a situation.  The pieces are almost all owners - read overvalued.  Repairs made by technicians who are not deeply experienced in the setting of your particular brand/model are often insufficiently.  Which leads you onto the OEM repair service that is overvalued.

  The result is that once a laptop is spent on the brand of 3 years, repair of such a system in such circumstances: the replacement more often.

  Well consider a desktop computer type for a replacement.  They are cheaper to begin with, usually more powerful - sometimes by a factor of 2, are easily repairable using components of off - the shelf that are commonly available and one made by several competitors.   Desktop computers usually hold up well almost two times longer.  From an ergonomic point of view, laptops are considered experts machines of 20 minutes.  Use of meaning beyond that time can be bad for your health.

• Window remains white screen after starting windows screen. the system hangs after Mup.sys on safe mode

  The title pretty much everything said.

  The problem occurred on a fault that Dell Vostro 2510 with the additional option should only do the downgrade of Win Xp (from Vista).  As noted, on normal startup, the system will remain in a blank screen after the Windows Xp "loading" screen.  And on safe mode, it will join Mup.sys and then hang there.

  The closest thing that I got from a web search was a thread in forum saying that the official info from Microsoft was that it was a question of Win Xp/motherboard (http://www.hardwareanalysis.com/content/topic/31874/?o=40 halfway to a post by Bobb Fwed).  The poster provided no link, so I don't know how official his info was really.

  Thank you

• Pavilion G6 1010SA: Blank screen after start upward

  Unless I leave my laptop on sleep I get the following problem: when I then start it starts (power light & fan on and I hear cd rom as it starts) but there is no display on the screen at all, it is only black. Either by the way, the blue light caps lock shift flashes once every five seconds then stops, then continues the cycle. I went through all the normal fixes (remove the battery press button start for 30 sec etc etc no luck) and after perseveering attempts of 40 or 50 by pressing F8 repeatedly at the start I finally get a result.  and I am offered beginning of normal startup mode / safe etc. and then windows 7 log on screen performance. Evertime I get the screen back, I noticed that the date is returned in May 2009. Other small things like no sound setting when I click on the desktop icon are also apparent. Restore to an earlier time makes a difference in the way.

  Is this all along the CMOS battery? I know it's in a nearly inaccessible spot on this laptop!

  Also, I tried to reload the BIOS on the HP site but it has no effect (despite the fact that there is an update this year apparently).

  Help?

  Hi @WaterlooSunset ,

  Thank you for visiting the Forums HP's Support and welcome. It's a great site for information and questions. I looked in your question about your HP Pavilion g6-1010sa Notebook and the problems dated back to 2009. Try to check the RTC battery. Could be low and causing the time clock (RTC) incorrect real which would cause the error of the internal battery. Here is a document to show you how you can replace that.

  Hope this helps you.

  Thank you.

• White screen after starting the desktop computer

  Original title: Windows 7 white after the start of desktop screen.

  When windows starts my desktop appears for 5 seconds and then the screen become white. I can't do any of that except the computer restarts.  When I do this, white screen closes and I see my office, but which also closes and the system restarts with the same question.   It seems that something is loading right after my office that does not... I can't access to my office to see what is on... Any thoughts on how I can fix this, other than a system restore?

  I have a solution

  First of all causes of white screen most of the files exe as spyware or viruses is the best way to solve this boot

  on winpe CD or DVD from winpe, the research of malicious software which load at startup

  If you don't know what file is it tries to start the Task Manager when connecting

  to do this, go to system32 and then make a copy of cmd.exe and rename the copy sethc.exe and replace the current sethc after this restart let it connect normally, then pass the user pressing a win + l and then press SHIFT 5 times then a command prompt should appear then type taskmgr.exe and then find the process and kill it and remove via msconfig or winpe sorry for my bad English

• DON'T LOG ON THE SCREEN AFTER STARTING UPWARDS

  Hello

  When I woke up, my computer was in hibernation, and then when I turned it on, everything was different, including my personal settings. Then I started to download my themes because I couldn't find my personal stuff. Then I managed to get my themes, I rebooted my computer, and then all my personal stuff was back to normal. I had downloaded a log on-screen softwear before restarting the PC.

  After the reboot, everything worked well. So I decided to restart, just to make sure that everything is fine, then it starts up normally and loads normally well, but after that the screen is not black, no log on screen for detection of face or password. I've been close and turn my PC for the last two hours and nothing has changed, please help, I have a request that I need to present and I need your help

• Blue screen after starting on Satellite A60

  Hello

  I hope someone can help me on this: I haven't changed anything on my A60, but all of a sudden, I get a blue screen saying there is a problem with the atidvag.dll (?).

  I can only start the computer in mode asaved now. Thanks to google I found others who had the same problem and which may help to a new version of the bios. When I try to install the latest version of the bios on toshiba website it gives me a message as it could not load the driver...

  Thank you to anyone to help me with this, because I don't know what to do at all.
  BR,
  Bernhard

  Remember that the file atidvag.dll is part of the graphics driver.
  So, everything seems like a graphics driver or graphics card would be a malfunction.

  The best way to know what might be wrong is a use of the Toshiba Recovery CD!

  But if it is not possible to install the OS on the recovery CD, then you must contact the ASP in your country.
  Maybe the graphics chip is dead

• I have a black screen after start up, but the mouse behaves normally. What's wrong?

  Hi, today I turned on my Pavilion DV9500t off for an hour. It would normally start Windows 7 64-bit (the Welcome screen was during more than usual), but instead of going to my office, the screen went black with the cursor has normally and only flashes do not. No keyboard function works well.

  I started from the install disc and from there I fixed start-up (no problem found) and restored to the previous points several times without success.

  There is no error message and I have not noticed a strange behaviour, with a view to this. Any suggestions as to the cause and the cure are greatly appreciated.

  I suggest you reboot your device and pressing F10 to enter the BIOS. While in the BIOS, I ran the disk hard self test in the diagnostics tab and see what the results are.

• After overlaying Air SDK 3.6, iOS projects show a blank screen after start-up.

  Hello

  I recently covered 3.6 Air in Flash Builder 4.7.  My projects use stage3D via Starling.  The use of the 3.4 built SDK that is installed with FB 4.7, my projects, compile and run fine with the debug and release.  After that just overlap the SDK 3.6, the projects work very well in the Simulator and on Android, but when I run the projects on iOS, I get a blank screen.  I returned to the 3.4 SDK and my projects work very well on iOS.  But, I'd like to be able to have access to the features of 3.6, any suggestions would be very appreciated.

  Thank you for you time.

  Chris

  Did you follow the exact guidelines?

  http://helpx.Adobe.com/Flash-Builder/KB/overlay-air-SDK-Flash-Builder.html

  (They have changed recently and are updated for Flash Builder 4.7)

  For step 4, all you have to do is create the folder empty tape - do not need to copy the other files with 4.7 and AIR SDK 3.6.
