"Baking is not a fix, baking just heats the chip up inside and futzes with the internals a little bit. The chip is still dead, and it is bad and will fail again. Baking is not a fix.

Replace it with a new one.

If we are talking about the AMD GPU problem from 2011, yes, that CPU has integrated graphics. The blanket fix is NOT about making the system use the integrated graphics, it is about heating it to 125c long enough for the chip to &&^& itself up inside that it works again.

If we are talking about the NVIDIA GPU problem from 2007-2008, there is no integrated graphics there whatsoever that you can switch to."

If you experience more problems, I would take the laptop back to another Apple store, or at least try to get another tech. Apple has become more and more generous recently with replacing these machines as it becomes obvious that the video issues are a massive epidemic. Personally I've taken at least 7-8 machines in, and I've never been rejected when there is a confirmed MacBook Pro GPU issue.

"The best solution is to reball or replace the nvidia G84-602-A2 (A1226) and it work. check my work.

This process also works in A1260 using ATI X1600"

"I would also try taking the machine to an apple authorized service provider or a different Apple store. They would just need to confirm the issue by running a Graphics Processor Test on the machine to see if it qualifies for repair.

Also Nvidia in a class action lawsuit is offering repairs on certain models of machines with the chip issue. Details are online at:
