Hi all ...
As I described earlier I'm one of the unlucky customers to have chosen an Early 2011 MBP 15" with the discrete graphics card issue.
I've been talking to technical assistance in my home country (in Portugal) and with Apple Customer Relations Europe (in Ireland), specifically with Karen S. Feel free to contact her showing your view on this issue but let warn you beforehand that all Apple representatives were absolutely helpless in their approach to resolve this issue in my case. All of them denied my appeal without any further suggestions and without the slightest demonstration of respect towards me. They were just "sorry".
We have proof that this problem is related to the discrete AMD Radeon graphics card, more specifically with the solder used, and this is unacceptable planned obsolescence and ripoff. They sell you a new Logic Board and get 600€ plus another Logic Board without a single broken component. They just need to resolder (by reballing - check procedure in Youtube or ask Google) the connections and it's up and running to be sold again.
If you can't boot the machine in any way, there is one last method for you to try
This is not a fix, it is just a way to boot the laptop and it is probably temporary. You should not keep the machine running like this for long periods of time nor should you depend on it to render demanding graphics or videos. This method boots the machine using Intel's Integrated GPU.
With your computer turned off push the power button once like you would normally do to turn it on and immediately boot into single user mode by pressing simultaneously the CMD+S keys. (gotta be before the startup chime).
If you see a terminal executing commands automatically you can release the keys, If you don't startup and try again. When the commands stop in ":/ root#" type the following 12 commands, one at a time (commands are in bold; beware to respect all spaces, dashes and letter cases; omit where it reads (press return) as it is merely informational):
/sbin/mount -uw / (press return)
/bin/chmod -N / (press return)
/usr/bin/chflags nouchg / (press return)
/usr/sbin/chown root:admin / (press return)
/bin/chmod 1775 / (press return)
cd ~/ (press return)
mkdir DisabledExtensions (press return)
mv /System/Library/Extensions/ATI* ~/DisabledExtensions (press return)
mv /System/Library/Extensions/AMD* ~/DisabledExtensions (press return)
touch /System/Library/Extensions (press return)
reboot (press return)
After this the computer should restart normally with slight possible differences in color, contrast, brightness and resolution settings.
What these commands do is position the files responsible for interpreting/controlling the discrete GPU chipset inside another folder so the system can't initiate the discrete chip and automatically chooses the integrated one. The first 5 commands deal with permissions to allow you to manipulate the files, The next 5 commands deal with changing all required files from one place (System/Library/Extensions) to another (~/DisabledExtensions [~=var/root/]) and the last 2 commands save the changes and reboots the system.
If you have the opportunity to change logic board for free or if you choose to have the GPU reballed for less than 100€ (please whatever you just don't pay for a new logic board) remember to reverse this method by repositioning all files that you've put in the folder ~/DisabledExtensions back to the folder System/Library/Extensions. To do this repeat the process described earlier with the following exception: Substitute the 3 commands after cd ~/ by mv DisabledExtensions/A* /System/Library/Extensions/
Given the mistreatment I've been witnessing in my case and many similar others I can already promise I will never buy an Apple product again and I advise you to do the same. This is daylight robbery.
Nevertheless, I will not stop fighting until I see Apple assume responsabilty for their fault. Do the same by leaving feedback here https://www.apple.com/feedback/macbookpro.html and use all means available to call for Apple's responsability.
Hope this helps.
Best,
H.
