I'm having the issue that a lot of people have with their MacBooks. It's a MBP 2011 15" and it's suffering from the dedicated graphics failure. I get the lines down the screen, screen shifting, and completely shutting down as most people report.
I tried to take it to Apple for the recall by they said it passes their tests and does not qualify for the recall. I have images and video of the graphics failure occurring and sometimes it won't even boot.
I've tried running the Apple Hardware test but with the short test it reports everything is okay, despite their being red lines running down the screen during the test!
What can I do?
