An update on my post from Jan. 20 2015 (page 758) indicating that I had the same graphics card problem (Late 2011 15" MacBook Pro). Like many on this thread, I was frustrated, to say the least, with the situation. Currently, I'm really happy with the outcome and feel Apple took care of me well beyond any obligation I felt they had.
Only because a previous post had urged me, I went to the Apple online support and requested a call, asking for an exception because I am way past any warranty coverage. I received a call within an hour, was asked about the problem, given some tests to preform and told that it was likely graphics card related. I refrained from mentioning that I already knew the problem which seemed to be a widespread issue. After being advised to take it to my local authorized dealer (no Apple Store in the vicinity) for diagnosis, I explained that I didn't care for the local dealer and would rather send it directly to Apple. The representative put me on hold while he consulted his supervisor.
When back on the line he said that he'd make arrangements to ship the computer, diagnose and repair it. He gave me a case number, took down my shipping info and said a box would be sent to me which I would use to send them my mbp. The last thing he did was ask me for a credit card number, saying that they would repair it for $330 without specifying the extent or limit of the actual work. I gave him the info and two days later received the shipping box which was labeled and prepaid Fedex. I backed up what I could and sent it off.
They kept me up to date with emails and in less than a week they sent the computer back. It looked and operated like brand new. Here's what was replaced according to the packing slip:
Logic Board 2.4 Ghz
Display Clamshell Antiglare Hi-Res
Battery Li-Ion 77.5 WHr
Top Case w/Keyboard
MagSafe Board
The only piece I can recognize is the bottom cover with the serial number though they did replace some missing screws. Inside is still the same aftermarket Samsung SSD and 16 gb ram cards that I installed as well as the 1Tb Hdd that I had switched out with the optical drive. Everything else is new (or refurbished). This was a four year old laptop that I had used extensively, abused, opened up many times and, at times, put back together with missing screws and parts. I had recently replaced the touchpad and battery because of issues I attributed to heavy use and wear. I wish I hadn't just replaced the battery, but oh well
I don't think I would be happier had they sent me a brand new 2014 MacBook Pro considering the upgrades and custom configuration I have. Sure maybe they should have fixed it for free, but I'm more than happy paying the money and having my computer come back with all new parts, working as new and with all my apps, settings and data exactly how I had it.
I checked my credit card account to ensure the repair wasn't more than the $330 quoted (plus tax) The charge for that amount wasn't posted until the day they sent it back to me. Needless to say I'm more than satisfied with the outcome and am a devotee once again. Thanks Apple, thanks thread.
