Q: 2011 MacBook Pro and Discrete Graphics Card
-
Jan 30, 2015 8:55 AMby jimoase,I am at a loss right now to verify your comment because my machine is out for delivery in New York.
I have two operating systems that I use 10.9 and 10.10. During the heat of the battle to get my MBP to run an extra day or two I used both operating systems. I might have not exactly describe the name of the Energy what ever in System Preferences but you found it anyway. On my system in the upper left corner was a line about the graphic card with a check box. When I clicked it the "A" came on (gfxCardStatus) so I clicked it off immediately knowing that will crater my machine.
Of course that option does not exist on this iMac, also running 10.10.2, because there is only one graphic processor choice.
Does anyone have 10.9 running on an early 2011? Is that graphic processor selection option available to you?

Mountain Lion and earlier OSX don't have check box for Automatic graphics switching.

Jan 30, 2015 4:24 PMby ajb Architect,My own formerly trusty Macbook Pro (15" Pro 2.2GHz Quad-core Intel Core i7 / Model Identifier: MacBookPro8,2). Began to act erratic about 5 or 6 months ago - suddenly displaying nonsense (finely spaced lines and dark bands) from time to time after hours of use. These episodes became more frequent recently until the screen eventually went blank.
Usually a restart (after letting it cool down) would work for a while, but eventually even this stopped working. Now I can't depend on it anymore and need to replace it - however, it's an expensive Macbook.
This is really frustrating, as this is my primary work laptop - and I can no longer depend on it.

You certainly didn't just sit there and watch the problem get worse now did you?
Besides that posting your problem at the bottom of this very long thread is certainly not the way to get your problem noticed. It almost appears that you really not interested in getting a solution to your problem.

We can never know the heart of another. I think it would be less than polite to suggest that you have a better choice for someone else's life than they have.
From all reports there is growing evidence that Apple is a poor choice for repairing this problem because so many are reporting multiple repairs for the same problem. Some are reporting that if you get to 4 repairs and experience another failure Apple gives you a current production machine. Nice unless you have a 17" than its a degrade because there are not more 17".
Apple maybe the worse place to have this problem fixed because they have, so far, only one solution, replace the mother board with another board built at the same time the epidemic of failures were built. Apple demonstrated with their immediate firmware change that the problem was heat related and slowed the chip clock. Other manufactures use the same chip at a higher clock rate without this spike of failures. Therefor the problem is how Apple builds this chip into their printed circuit boards.
There are several "cures" being attempted the least reliable appears to be the Apple cure, swap the mother board. Next cure is reflow the solder and others are replacing the chip using different solder. Its too early to know which of the last two is the best. We know that the failure rate with the Apple cure is high. I have read that most folks who had the chip "reflowed" are happy. I am having the chip replaced and will let you know how that works out. My test will be running all applications and websites that use the accelerated graphic processor 24x7 for a couple of weeks non-stop while monitoring temps.
Apple may dodge the legal responsibility for solving this problem but Apple's manufacturing will not have demonstrated that it can solve this problem in future production. That will take another bite out of the poison Apple. For history buffs look up the father of the computer and how he chose to died.
