    I wonder if some of these issues could be causeed by OS versions / revisions and hardware conflicts?

    I wondered the same thing at first, too. The speed with which my problems started made it seem like there must have been a bad update to my Thunderbolt driver or something. But then it seemed very much like a hardware problem while I was troubleshooting it (and given that they replaced the main logic board to "fix" it - three times).


    However, when I got the MBP back from service after the third repair, I noticed that the Energy Saver preferences screen subtly changed. When I sent the unit in for the final repair, it looked like this:



    But when I got it back, it looked like this:



    The control to enable or disable the computer to stop using the discrete GPU changed from a checkbox to a radio button. Very mysterious.

    Todd, What version of the OS did you go from/to? Do you have a late or early 2011 model?


    Mine started about an hour worth of use after upgrading to 10.8.5. It had been rock solid until that point.


    I'd put it back as close to stock configuration as I could with totally fresh install of 10.8.4 on a blank drive and no migration of my previous settings. and it's been solid all day - 98% of the day discrete and an hour running the Heaven graphic benchmark. 2% of the time manually switching back and forth between integrated and descrete.


    All last week it'd been impossible to use and impossible to boot. I really think that a driver change in 8.5 was causing my issues and boot issues by leaving the card in an unstable state? But then it would happen if it has been powered off for the day too. I'm sure it's a compex issue.


    The energy saving panel has radios in 10.8.4, I don't remember what it was in .5. I've seen that 10.9 has a check box - maybe that was introduced in 10.8.5? I've seen numerous threas about power management issues with 10.8.5.


    I've put back in my 16gb ram upgrade and it's still stable. I cloned the drive and I'm going to upgrade the OS tomorrow and see if that changes things.

    Early 2011 15” 2.3 GHz Core i7 AMD Radeon HD 6750M – screen glitches ( Image Distortion, screen blurring, freeze and shift), boot problem ...

    FIXED: reballing GPU ~ 50 EUR and now I’m more vigilant with internal system temperature:

    1. Installed FanControl – and change (in more aggressive way) relation of fan speed – sensor temperature.
    2. I use laptop with an external monitor – now my lid is always open !!!
    3. I use a simple cooling pad
    4. I use only occasionally Windows virtual machine (Parallels).

    Good luck.

    I did this today as well in Los Angeles.  Googled reballing los angeles and found 5stars computer service.  So far, so good - 10 hours straight of discrete graphics and external monitor since the repair.  It cost $150, took 2 hours, and has a 60 day warranty.  The technician suggested I get one of the USB fan trays and keep the machine as cool as possible.  He also thoroughly cleaned the ventilation which apparently was pretty congested, despite my previous attempts to clean it.  Interestingly, he also mentioned the thermal paste had pretty much liquified and put new paste in.


    It wasn't a true reballing (as I understand it) - he used the same solder and said they could only do it that way when I initially asked.


    Here's hoping this makes it another 2 years.  I must run Parallels all the time and my computer is no stranger to daily stress testing.  Will post any updates.  No news is good news.

    Good to hear this works for you. To every else, I highly recommend not doing performing this fix makeshift, short-term, bound to fail, workaround:




    "Reballing involves dismantling, heating the chip until it can be removed from the board, typically with a hot-air gun and vacuum pickup tool, removing the device, removing solder remaining on the device and board, putting new solder balls in place, replacing the original device if there was a poor connection, or using a new one, and heating the device or board to solder it in place.....Chips are at risk of being damaged by the repeated heating and cooling of reballing"







    and as for (1-4)....your GPU is now working harder - rendering for a larger display, and the thermal limit is now reduced. You are also subjecting peripheral components on your logicboard, including your CPU, to damage by altering the GPU's power's a circuit, which is now drawing more amperage than it should be. Your GPU will fail, completely, within a short period of time (I'll set the over under for 90 days).

    nbar - maybe you're right.


    1. July 2011 - purcase the computer - I used an external monitor from day one

    2. January 2013 - problem start

    3. Feb 2013 -    reballing


    Untill now (Octomber 2013) everyting is ok.

  • nbar Level 5 Level 5

    I apologize for coming off as harsh and I was sincere in saying I was glad this worked for you. My concern boils down to the fact that this thread involves many users. Given that, I felt it necessary to respond accordingly and stress the dangers of taking this route. That being said, it would be remiss of me not to qualify my comment as what it is: merely my opinion on the matter. Other followers of this thread should take it just as that.

    I have the "early 2011" model. I can't remember when I upgraded from 10.8.4 to 10.8.5. My point, though, is that when my laptop came out of service, the energy saver screen looked different than when it went in. I don't understand how that's possible unless they mucked with the software as well as the hardware at the service center.

    I hate to ruin dreams of those involved in the reballing efforts, but an authorized repair centre here tried the same thing...three times.


    JUL 2011 - purchased Macbook

    JAN 2013 - problems started, did reball 1

    FEB 2013 - problems returned, reball 2

    MAY 2013 - problems returned, reball 3

    AUG 2013 - problems returned, didn't want to reball anymore

    When it comes to reballing it may be a good idea to look for a good(!) place to perform these actions. Preferably some with industry experience (and those usually have access to replacement chips as well).

  • Neshill Level 1 Level 1

    An apple ASP (authorized service provider) performed the services, and they have plenty of experience I'd surmise.

  • matthewadams Level 1 Level 1

    Oh.. I didnt know they were performing reballing. Figured they'd go for full-on logic board replacements only.

  • maiku Level 2 Level 2

    Same thing here. Early 2011 Macbook Pro. After the 10.8.5 update, upon booting, the screen was shifted to one side with a big black line down the middle. I changed the resolution, the system froze. I rebooted to a white screen, the computer got very hot, fans running at full blast. I shut it off, tired to boot into safe mode, no luck. Recovery mode, no luck either. Tried to boot from my Time Machine backup, nope sorry. I keep getting to the same spot in the boot process where, I'm guessing, the graphics card switches over from using the Intel HD Graphics 3000 to the AMD Radeon HD 6750M. I was finally able to boot after resetting the PRAM then booting while holding Shift-Command-v (shows Safe Mode progress). Right now I've got it running off the onboard Intel graphics  and if I click "Allow automatic grahics switching..." the system freezes up.


    I have an apointment at the Genius Bar at 3:00, we'll see what they say. Could this just be a grahics driver problem? I'm hoping this is just a software problem and not fried hardware.

    What so interesting is that we are all experiencing this issue for the first time at around the same time."


    NOT TRUE...after a month of owning (bought brand new) my mbp 2011 (17in I7 2.2ghz) I started getting the "blue" screen now and again...And brought it to the local Apple store where I bought it for this and another minor issue...At the store, I was not able to reproduce the blue screen and they could not find anything wrong with it. My solution to date, when I get the "blue" screen is to close the lid, wait a few seconds and reopen the lid...Hopefully now that MANY have the same problem, I will be able to get this fixed BEFORE it gets worste (took Apple care on this laptop).

    I even read yet ANOTHER post about it on Apple Insider, which was posted Monday about how this is affecting all pf us!!
