I have a 15" early-2011 MBP that ran great for 4+ years before going down to Radeongate last September with the usual symptoms. Under Apple's repair program, I brought it in and they replaced the logic board for free. It ran for about two months before it happened again. I brought it in again, and they replaced the board again with what they claimed was a brand new one. It was working well until about a week ago, when it wouldn't boot up. Rather than the typical video issues or the blank white screen, the machine would either freeze up just after login or sometimes get stuck at the loading screen and start making beeping sounds. I did some investigation and found that the beeping indicated a RAM problem, so I swapped out the RAM, but that didn't fix the problem. Suspecting the video card again, I tried going into single-user mode and attempting the workaround where I delete the ATI drivers, but that didn't fix anything either. I brought it into the Apple store yesterday, and they tried their RAM as well and didn't get it to work. They said it was likely a problem with the logic board, and that it would have to be replaced. They tried to run a graphics diagnostic, but the machine would freeze before they could do it, so even if the graphics card was the root cause, they can't test it. This is important, because since they can't tell whether this is the Radeongate issue again or not, they can't repair it for free and I would have to pay for a new logic board. I told them that they installed a brand new one last time, which they confirmed. The previous repair had a warranty of 90 days, so I'm out of luck there. I have a backup of my data, and I have another laptop I can use, so I'm OK as far as my computing needs. My MBP is basically a brick at this point though, and I'm not sure what else I can do in terms of getting Apple to fix it again or replace it. I'm looking for any advice or last-ditch efforts to get it working, even on a temporary basis, so that they can at least run the graphics diagnostic. It may be that it was just a bad logic board, in which case I probably can't do anything since the warranty ran out. Any ideas?
