• B540 TDR and black screen on startup

  Hi all, I bought a B540 in April a power works fine until end of July when it began to show the error "display driver has stopped working and has recovered." a few days later I let him (I have need as a wifi station to connect devices remove) and after a few hours of work, when I came back, the screen was off and there wa no way to turn it on. I press the power button for a few seconds to turn off the pc and he died. When I turned on, the computer started but the screen is off (not the 'lenovo' logo was shown on the eve) but everything else seemed to work (play plug/unpluging usb external hard drive the sound of the carachteristic). I turned off again and wait ten minutes before the market again, this time above the 'lenovo' logo was shown, but it seems that the pc failed to boot win 8. I unlplugged everything, removed the power cord, wait an hour and after that all started ok but the error message "display driver stop" was still there. After this date the computer randomly starts ok or with the screen. Given that I do not use it intensively Isuspected some windows update to cause this strange behavior and I'm trying to use a point of restoration, until July 17, but the problem was still there. Then I removed all recent windows update of June on, and I realized that in one case, it was not possible (i.e. the "remove/uninstall" button not showed that KB). I googled around and found the subject KB has been reported to broken system and the only way to react was to use a DOS command to reatore a new installation of the system. I did and actually everything works ok for 2 days (one day, I actually use the PC all day to upload stuff to iternet it to work). Unfortunately, after that day, everything seems to repeat: new 'pilot not resposinding to display' and a black screen at startup.

  Please consider that the system is quite new and clean (only 3/4 months of life) and everything works fine until end of July. What do you suggest me?

  
  

• Black screen problem.

  Hello!

  While I was watching a movie from Itunes on my iphone and took a screenshot. As I looked in my album, I ended up getting a black screen. There is a desire for this?

  

  I guess this is supposed to work this way because you don't own the rights to the film.

• iPhone 7 more stuck on black screen with the spinning wheel

  How can I fix it? I tried to reset, go into DFU mode, recover from iTunes. Nothing works. I can't use iTunes because he wants me to grant access from my iPhone is not responding. DFU mode doesn't work, the screen does not any combination of seconds I hold down the buttons to. This has happened more than an hour. Should I just wait for the battery to die? Please note that I do not live in the United States or the U.K. or anywhere with an Apple Store, I can take it to.

  Thank you

  Hello! I think that I may have a solution to our problem of the black screen with the circle of rotation.

  I came across this post today because my iPhone all nine 7 (which I've upgraded to the latest ios) also got stuck on a black screen with the circle of rotation. I tried to update some of my apps, when suddenly the screen froze. I clicked once on the home button and the screen become black with the subsequent appearance of the circle of rotation.

  I have tried everything - simultaneously press the home button and power (does not work). connected to itunes to do a restore (it won't let me not because my "find my iPhone" was turned on - but I could not turn off because my phone was insensitive).

  In any case, a very useful Mr. Damon (Senior Advisor to Apple) helped me via chat to solve the problem.

  Here's what I did:

  1. make sure that your iPhone is disconnected from the socket or the computer.

  2. hold the POWER button and the VOLUME DOWN button at the same TIME. If it works, the screen should turn off almost immediately.

  3. connect your iPhone to the computer. (when I have connected to the computer, my iPhone automatically on and was ready to be reused).

  The steps below are for those whose iPhones did not turn with the above steps. The following steps are designed to allow you to disable remote your 'find my iPhone', so you can do a manual restore from iTunes.

  4. go to www.icloud.com.

  5. click on Find iPhone

  6. given that the phone is turned off already, he won't be able to find it. On the top bar, click DEVICES.

  7. click on your iPhone.

  8. click on "delete account".

  9. go into your itunes and do a restore.

  I did have to do steps 4 to 9 more, because as I said, my iPhone automatically activated after step 3.

  This really worked for me. I hope this works for everyone else too! Have a great day!

• iOS 10 wheel black screen

  Been using iOS 10.0.1 for about a week on an iPhone 6 and it is buggy. The questions below are only occurred since the upgrade to iOS 10. Please fix in the next version or offer a solution.

  1 random black screen with the spinning wheel. The upgrade went very well, so not this black screen. But at least every day my phone stopped responding and displays a black screen with the spinning wheel. After 5 to 10 seconds, I invited me to enter my password as if the phone has rebooted. I'm not the only person knows - and even managed to capture the image below.

  2 - I activated the option 'open finger rest' in respect of the accessibility of the home screen, but this does not always work. Once again, about once a day, to rest my finger to open the results in me being invited to press the home button to unlock. Whenever this happened I checked and confirmed that 'rest finger to open' has been enabled.

  

  Thank you

  I have the same problem.  3 co-workers have the same problem.  I opened a discussion with the Apple support, however, they said it was just my phone and that I should backup my phone and do a factory restore.  This is pretty extreme, especially considering that 100% of my immediate peers with iPhone devices 6 face the same frustration.

• MacBook (2010) starts with black screen with flashing Apple logo

  I recently got ahold of a Macbook Pro 2010 running very slow so I did a reinstall of the operating system (which was a living nightmare, Macintosh is not as easy to manage as it was at the time of PowerPC) once I got to the top and running, I decided to upgrade to the latest version of El Capitan (an update (not an upgrade I already had a version out there) once I rebooted and let the computer do its thing he began to start up normally, but after finishing the progress bar, he went to a black screen (with the screen still on) that flashed the boot from time to time Apple logo. I forced shut down the computer and start in safe mode with success (that's how I'm typing this post now).

  Thanks in advance.

  When you reinstalled, did you remove any third-party system before reinstalling.

  A Mac that runs in Mode without failure, but are generally not normally indicates some incompatible system changes.

  Software common problems are things that are intended to clean, protect, optimize, accelerate, or otherwise maintain your Mac.

• Black screen for 10 seconds and then lock screen after ios 10

  I am facing a problem where my iphone 6 randomly shows a black screen with a loading circle in the Center for about 10 seconds and then wakes up to the password lock screen.

  Called in support and they mentioned to install ios 10 via itunes instead and a new device settings and do not restore the backup to diagnose the problem.

  Is anyone else having the same problem? Any suggestions that might be faster than the one mentioned by the Apple Support

  Colleague and I have this specific question. Getting really boring. The app I was on lost its place, its similar accidents are happening

• I need help on my macbook pro i5 13inch mid 2012 model when I open all black screen

  I stopped just my macbook pro, when I open all the black screen but it has power... can I bring it to apple store to fix. How will they charge?

  The cost will be dependent on what may be wrong.  It could be the GPU or the screen is who is several hundred dollars.  It could be the connection of the screen, which will be very little costly to repair or even for free if only the connection is loose.

  Foe a final quote, bring the product to an Apple store genius bar.

  Ciao.

  Bring her back. It's new, it's at the shop for sorting or replace it, not you to try to fix it.

• phone calls disconnected with black screen cannot close

  my iphone screen 6 turns black while talking and calls disconnected - cannot disconnect caller or turn off the phone

  I cleaned the (sensor area) and removed the protective shield - I also 'reset statistics' under cell which worked for a few days but now turns black screen while calls speaking, be disconnected or conversations break up - can not turn off the caller's phone - I have the latest update 9.3.5

  "Protective shield"?

  Its existence on your iPhone is maybe a problem.  You can try to use the iPhone without this "shield" because it can hinder the iPhone proximity sensors.

• 10.11.6 - black screen with cursor in security update 2016-001

  Hello

  After installing safety day 2016-001 10.11.6 and reset as part of the installation process, I get a white apple logo, the white line will blink twice and then I get a black screen with white cursor. The cursor moves with the mouse but nothing happens and I do not get the login screen. This happened on my MacBook Pro and my iMac (retina 5K, end of 2014) (2015).

  Any help is greatly appreciated.

  Best regards

  Same problem with iMac 5K, no problems with MacBook 2016 if. Very glitchy update indeed.

• iPhone is disabled (titled in a black screen)

  days, my broken iPhone screen, so it worked without me touching even it... then he entered my password randomly and then disabled... and was unusable until I have fix it... now I set the screen and everything... and I KNOW my password... I even put it into restore mode for update and then hope to get the screen "enter in the access code"... but even after the entry "update" and update to the latest firmware he signed again an iPhone is disabled in a full black screen even if I don't want to lose anything since I know my password and I don't want to not erase completely to its default... Thank you for helping...

  Once the device is disabled, there is no way to recover the data, or access a screen to enter the access code. You must restore it to try to recover, and then you can restore the device to your last backup. Right now, data on the device is not accessible.  If you have forgotten the password for your iPad, iPhone or iPod touch, or your device is disabled - Apple supports
