Just got my MacBook Pro back from its third repair (2 motherboards, and one battery that failed prematurely) and it looks like the "fixed" machine still has the same graphics problems I'd brought to get fixed. Both motherboard replacements were repaired under their free repair program, but I'm not sure it's actually fixed -- or perhaps the part they replaced it with has already failed? (Seems unlikely). I haven't brought it back to the store to have them do their diagnosis, but visually it looks like the same problem they diagnosed in the past. First question -- does anyone know how to access the hardware diagnosis screens they bring up in-store? They're different than the ones I know how to do on my own. Second question -- what has Apple done for you in these scenarios? I was without my primary work machine for five days, but it seems I've still got the same problem. I had AppleCare on this machine, but it is an Early 2011 MBP, and I'm well past expiry on that -- though their repair program for the video card issues goes through the end of this year. I can bring it back in, and see if they can diagnose the same (or a different issue) but that likely means being without my machine for another 5 days. Colleagues of mine, after a series of in-warranty returns, have had Apple give them a new machine as a replacement. Anyone else have that experience, or can provide guidance about how best to have a usable machine from which to work? thanks.
