Hi everybody.

I have a problem.

Sometimes after the starting chime and the apple logo grey screen, my mac would show for a few moments a strange screen with little white "rectangles"  filling the grey space. (see image).

Then, once that's what happened: I left my mbp in sleep mode but when I lifted the screen to activate it, the computer would not respond. The LED went off. After a few second I was prompted another very strange image.

It seems to me that a similar image appeared when, using Safari and opening or closing a new tab, the graphic card switches from one to the other (I have gfxCardStatus v. 2.0.1).

 

Does anybody have any hint or idea about what is happening?

 

BTW I am completely under warranty (It is less than 2 months old). Moreover I tried to perform the Apple Hardware Test (both "normal" test and "deep" test). Nothing wrong was found.

 

PS: I am writing here because it would be quite annoying for me to take my laptop to an Apple center and have it checked. I need it. That would be the real least resource for me.


MacBook Pro, Mac OS X (10.6.7), Early 2011

    Greetings,

     

    That certainly is a video issue of some kind, although if it only happens occasionally it may not be a hardware failure.

     

    Questions:

    • How often do the white squares appear at startup? (Every time the computer is turned on...every 5th time etc.)
    • Do they happen only at a cold startup (when the system has been powered down for over 30 minutes) or does it also happen if you turn the computer off and then turn it back on within 5 minutes?
    • Have you added any memory / changed the hardware in anyway since you received the computer?
    • Do you have any peripherals connected when this issue occurs?
    • How much free space do you have on the internal drive and do you have an external drive which is formatted for Mac OS available?

     

    Troubleshooting:

    1. Reset the SMC and then test: http://support.apple.com/kb/HT3964
    2. Reset the PRAM and then test: http://docs.info.apple.com/article.html?path=Mac/10.6/en/26871.html

     

    Cheers.

    These white squares appeared three times if I am not mistaken, not at cold startup but one after the other.

    I have added no memory or other kind of hardware.

    I don't remember if I had an external Hard Drive connected all the times. But definitely at least once, because I tried to boot from it, in order to install Snow Leopard on that drive. But when I chose the drive (Mac Os Extended Journaled Formatted) the "loading gear" after a while would freeze and then I had to force the shutdown and restart... thus, after selecting the internal hard drive for startup, here it comes the squares...

     

    At the moment I have a bunch of free space, 183 GB.

    BTW: after SMC reset and PRAM reset it seems to have improved a lot in performance. The stickies now load immediately. Before they had an annoying delay.

     

    Do you think this operation can help with my problem?

     

    Moreover I have installed and uninstalled different softwares since I bought it. In order to try the performance as well. And I needed the external mac os bootable drive because DiskWarrior has shown a 30% of "things" to be ordered.

     

    1) Why do you think my external HD won't load? (it is a 2.5" HD taken from my previous MBP early 2008 now put inside a very minimal HD box connected with 1 USB cable).

    2) Why has SMC so bloodily improved the performance?

     

    Thanks a lot!

    I'm unsure why you would need to install software or run disk warrior to "improve performance" on a brand new computer?

     

    Don't run Disk Warrior on a regular basis.  It is useful for recovery of a damaged drive but its method of repair is highly invasive and can do more harm than good if used all the time on a healthy drive.

     

    Reseting the PRAM clears the drive cache so it might be of minor assistance in general drive responsiveness but again, this shouldn't be done often and more importantly should not be necessary.

     

    Keep an eye on this video issue to see if it re-occurs.

     

    As to your external drive, it's OS may not be fully compatible with this model of Mac as the OS installed on it came from a different Mac.  You can try repairing it and see if that helps: http://docs.info.apple.com/article.html?path=Mac/10.6/en/8492.html

     

    Otherwise I would suggest you reformat that drive (after taking anything of importance off of it) and then you can reinstall an OS on it if thats your goal and put whatever files you took off that you wish to keep back on.

     

    Cheers.

    Alright. You're definitely right! Why should I run those Diskwarrior & co...

    Actually, the SMC reset really put things back to normal and fine. If anything should happen again, I'll contact the Apple Service.

    Cheers.

    Thank you so much for your help.

    Best

    Ok. Today I've taken it to an Apple Premium Reseller near my home. They'll let me know asap (1 week).

    I've never been so like as you have, dear Joni, but I hope that they can at least fix it well and for free.

     

    Cheers.

    I also have the same problem. Sometimes, the scrambled screen appears during startup after the spinning wheel and Apple logo have disappeared and right before the login screen appears. This scrambled screen appears for a few seconds, and then it goes back to normal, and I can use the computer.

     

    Other times, I have had the scrambled screen appear after I wake up the computer from sleep, and then stays scrambled, and I cannot use the computer and have to force reset it.

     

    Right now the computer is still usable, but I will probably take it to an Apple Store to see what they say.

    I've taken my mac to an Apple Reseller Premium. They've changed the logic board. But they would not give an explanation (not one!) why they would have done it. They would simply say what they'd done. I would have much appreciated a new one instead, in exchange for this with some polite excuses for such annoying matters.. after all I had bought it very recently, 35 days ago or so. Besides I had to buy this new macbook pro, because the old one had to be repaired... I should have payed around 700 € for installing a new logic board... ***! Right? So I hope it will work well... nothing more to add, honestly. It really costs a lot... just hope it works!

    Hi! I went to my local Apple Store, and the Genius immediately asked me if I had Air Display (the application that allows one to use an iPhone or an iPad as an additional display) installed. Turned out that I did have Air Display installed, and this was causing the screen problems. I uninstalled Air Display (you have to use its uninstaller to remove it completely), and the problem disappeared.

    Hi again.

     

    Great news: In Mac OS X 10.7.2, Apple has fixed compatibility with Air Display on all but four particular MacBook Pro models. We've just issued a new version of the Mac support software for Air Display that enables the drivers on all of the machines that work on Lion. If you have Air Display installed, please select "Check For Updates" in the Air Display menu. And update to Mac OS X 10.7.2.

     

    The Air Display 1.5.1 virtual video driver will still disable itself on these MBP models:

    • 15" MacBook Pro (late 2008 and mid 2009)
    • 17" MacBook Pro (early and mid 2009).

    Hi,

     

    The similar problems have iMac 2011 with AMD Radeon 6970M Video Card,

    http://support.apple.com/kb/TS5167?viewlocale

     

    in the service of Apple computers, they said they have 1-2 such cases every week. Apple to have not yet admitted, but it is the same problem as with the iMac.

     

    Tim Cook, we like yours new iPhone, but we are MacBook Users and we are angry!!!

     

    Apple, why do not you respond?
