Hi gammapoint, would you mind sharing how much that service repair cost (roughly - even an above/below X sort of thing is fine) and how you convinced them this was the issue (or did their verion of Apple Diags figure it out)?
I just started having the exact same issue as everyone else here on this thread (locked up, red [and blue] screen of death, split desktop, etc...). Any type of load causes (which causes the system to switch to the ATI) my 15" to freeze. I have to zap PRAM before it will come back. From what I can see, once my latop switches over to the AMD/ATI, a variable is set in PRAM (or SMC) to the last used graphics chipset, and because it freezes I have to hard boot (haven't attempted ssh'ing remotely), which means that the last used graphics card (AMD/ATI) is still in PRAM and every subsequent boot attempts to use that card until PRAM is cleared (again, purely based on my own obsverations).
Its gotten so bad now that I can't even plug in an external monitor at all, as soon as I do, locked up. I have not had any issues until last week, and now its gotten so much worse. I'm lucky if I get 20-30 minutes out of it.
Reflowing the GPU will only extend its life by a few months and you risk Apple denying you a free replacement in case they initate a recall.
It's only a good idea if you don't care about Apple initiating a recall and/or you need to get data off your mbp (in which case you could do so easily)
Personally, I am going to get it fixed for the flat rate of $310 and hope their replacements fail 2 or 3 times, lol.
I have same problem with early 2011 15" macbook pro.
5 days ago I upgraded the RAM to 16gb of crucial RAM. First 4 hours everything was running great. Running it with secondary screen so no problem with the descrete graphics. Then freeze with the colorful horizontal lines.
Rebooted but the lines kept coming quite fast. After some minutes. Then it would not pass the grey boot screen.
Starting in safe boot helped me rebooting again.
Most of the time I can run the computer stable when forcing the integrated card with gfxCardStatus.
Sometimes when I started up and want to force the integrated card: (It is in dynamic switching mode but on the integrated) and I go to integrated Only) it freezes also. (10% of the cases)
Once I'm in integrated mode it never freezes.
When change to discrete mode I almost have the freeze imidiatly (90% of the cases). Otherwise after some time I have the freeze.
Things that help sometimes: clearing vram, booting into safe mode. Most of the time I don't have boot issues.
I changed the RAM back to the stock ram and I'm expierencing the same problems.
I'm now trying the smcFanControl but I'm not shure if it will help. Most of the time I have the freeze immediatly when I'm on discrete card so it seems kind of strange that it can heat up that quickly. I'll keep you informed about the smcFanControl testing.
Boot ROM Version: MBP81.0047.B27
SMC Version (system): 1.69f4
Today I upgraded from 1.69f3 to 1.69f4. Same problem.
So I guess still no magical solution?
Are there people who managed to get it solved permanently (maybe with some components changed)?
Thanks! Unfortunately these are expensive options. I was hoping for a budget friendly software solution or something.
I'm now trying smcFanControl. It seem so help but did not resolve the problem completely.
Forcing the fan speed at 4000, I'm able to switch to the discrete card and stay for a long time with no crashes.
I still had the problem one time so it did not resolve completely.
I think I noticed the crash already some months ago (2-3 times). But at each time it came only once. Reboot and no problem for months (Just thought it was a software problem).
I think it is kind of odd that the crashes just start the day I have upgraded the Ram. (But it is not the ram because now I'm on the stock ram again). I'm pretty sure I changed the ram in a correct manner...
Here's something I haven't tried (and Apple still has my MBP for repair, so I can't try it)...
In releases of gfxCardStatus prior to v2.2.1, the program allowed users to automatically restore the last-used mode at startup. In other words, you didn't have to fight to get a successful boot in order to set gfxCardStatus to integrated card only - that setting would just persist if you asked it to. Apparently this caused issues for some users, so with v2.2.1, Cody removed that feature and the program defaults to Dynamic Switching at each startup.
Those pre-2.2.1 releases are still available on GitHub, so you might be able to install one of those and use the persistent integrated-only setting to get you through boot reliably. However, keep in mind that:
- there may be weird side effects from the persistent setting if you have apps that try to fire up the discrete GPU at startup
- you won't be taking advantage of all of the bugfixes and improvements that have been made in later releases
But if anyone tries this, please report back about whether it worked! gfxCardStatus isn't a permanent fix, but it has helped a lot of users, and this could resolve the issues that people have with it returning to Dynamic Switching each time you reboot (and therefore potentially compromising the ability to boot).
My MBP crashed yesterday with the 3rd logic board. It happened during a presentation I was doing for my client... it's unacceptable!!!
The machine doesn't boot anymore and it crashes with a blue screen as soon as I try to run the disk utility or start the safe mode. I lost a whole day of work since I cannot access the content of my SSD.
I'm off to the apple store in a couple of hours...
Hey there Nix,
I'm having the same issues. Could you share your repair number at Apple store?
I have to return to the Apple store, and this is getting seriously on my nerves.
I've been trying (in vain) to show Apple that this is a widespread issue, and a recall must be started!

Anyone able to get ML to not see the AMD GPU? I was able to get it done in Lion by removing the kext associated with the card, however the Kext names changed in ML as well a some assocaitions it appears. When on Lion, the system didnt' even report the existence on the AMD GPU, only the Intel HD 3000. However, ML still reports the GPU. When a window around in ML, the window moves very slowly. Opening Safari, the window flickers and is really slow when trying to load the Frequented Tabs, like it constantly refreshing. I don't want to be stuck on just Lion.
It's rediculas that Apple hasn't (I haven't read the whole 135 pages) responded to this thread.
