    Tonight I heard of another problem with the discrete GPU on an early 2011 model - I think that they use the same AMD Radeon 6750M in my late 2011 model? I don't know if this is going to blow up like the mid-2010 NVIDIA card fiasco, but I would definitely take the machine into an Apple Store or an AASP and see if they are hearing of similar glitches.


    Good luck,

    I actually got the service info from my AASP, but they never heard of issues like mine. The fact that all of the references to this issue are localized around the end of January is curious to me.

    Can anyone check in the Apple Store? Maybe it's a known issue by now.

  • Neshill Level 1 Level 1

    I'd be curious to know (question to everyone affected): when you experience the issue, does plugging/unplugging the monitor in help remedy it for a short period?

    I will try again in a few days (some of my work uses 3d graphics and I discovered yesterday that I will need more than the integrated card to keep things stable), but the last story I was told at the Apple Store was that they cared about this issue on the 2010 models (and were doing free logic board replacements because it was a wide spread issue)... but there was no such flag in their system for the 2011 models.


    As for your second question, this only happens on my laptop, and I don't use a secondary display so I cannot unplug it or plug it back in.  Sorry!

    I'm having exact issue. Early-2011 model. After installing SMC Firmware 1.7 update discrete card stoped working properly. I found it while working in xcode (running Simulator switches to discrete card I guess) and launching HD video. Plus I'm having vertical 1px line sometimes (but it could be fixed by tapping the screen).

    Probably the solution would be to roll back to Snow Leo/Lion or waiting for another SMC update from Apple (if they aware of it)...

  • abelliveau Level 1 Level 1

    My problem started way before the 1.7 firmware update, so I'm not totally conviced we are experiencing the same issue.  In any case, I bit the bullet and brought the MacBook Pro into the Apple Store to have the logic board replaced.  The 2.2 Ghz board cost $502.55, plus a $39 hardward repair charge and tax.  The Apple Store I brought it to quoted me a one week turn-around.


    Definitely a costly repair, but considering the price of the laptop itself... It hopefully will be worth it in the long run.

  • Neshill Level 1 Level 1

    Sigh. Best of luck, I'll probably do the same next week.

  • mnemon1c Level 1 Level 1

    So the problem was with whole logic board (not just with the Radeon card)?

  • Neshill Level 1 Level 1

    You can't actually replace only the radeon chip, you need to replace the whole logic board :/

  • cyberdude3k Level 1 Level 1

    I think it might be the 1.7 SMC firmware update, I had all the symptoms and AppleCare. The computer just stopped booting after the grey screen so I had them replace the logic board, when I got my Mac back the 1.7 was available, thinking that was not the issue I installed it and now I have the same issues and the computer won't even boot up after the grey screen.


    I am going back to the apple store, let's see what they say!

  • mnemon1c Level 1 Level 1

    Thanks fro the update. Please let us know how the things go.

  • Neshill Level 1 Level 1

    Unfortunately these issues started happening before the 1.7SMC for both of us. I actually hoped the SMC would fix that.


    An update is that I got my MacBook back from service. They soldered in the graphics chip again and stress tested the laptop a great deal, so now we have to wait and see if this helps. It's cheaper than replacing the logic board so it might be a good solution for those who don't have the budget.

  • wilersonoliveira Level 1 Level 1

    I've been having these issues as well, since the end of January. I was running Lion at the time. Since then, I have upgraded to Mountain Lion and applied the 1.7 SMC update, but the crashes continued happening. I have installed gfxCardStatus and as long as I keep the computer using only the integrated card, nothing happens.


    Neshill, have you soldered the graphics card twice? Isn't that harmful to the laptop? I've been refraining to send my laptop to service because I'm using it for work, but I might try that later.

  • abelliveau Level 1 Level 1

    cyberdude3k, I am curious to see what the Apple Store says in your situation. That may be a different problem, though.


    On my end, I just picked up my MacBook Pro.  It took about 6 days for the repair (dropped it off last Sunday, picked it up this afternoon).  I ended up replacing the logic board and the battery (which wasn't really holding much of a charge anymore).


    While I was in the store, I tested the graphics card.  Using gfxCardStatus, I can now switched between integrated and discrete and the computer no longer crashes!  Woo!  When using the discrete card, the screen does take on a *slight* blueish tint, but it is not nearly as noticeable/strong as before.  It is hardly noticeable.


    While I was in the store, I installed the two available firmware updates (one pertaining to the bluetooth drivers, and the SMC update).  Rebooted, and again - everything seems good.  I can switch between graphic cards (or leave it on dynamic switching) and everything is working smoothly.


    The repair comes with a three month warranty, so hopefully if anything is to go wrong, it will do so within that time frame!  But it does look like replacing the logic board fixed my problem.
