I have two MBPro 15" 2.4 Ghz. One of them I bought in Milan, Italy, on September 2007, for 2200,00 EUR, which is the MBP 3.1, model A1226. The other one I bought in Toronto, Canada, on May 2008, which is the 4.1 (A1260) and with this one I also bought the Applecare. Both are equipped with the Intel Core 2 Duo 2.4 GHz
On January 2010, the MBP 3.1 presented me the Nvidia issue (apple article: TS2377) with the chime on boot and the blank screen. Brought it to an AASP in Madrid, Spain, with the TS2377 article in hands. They ran the USB Nvidia GPU test, not in front of me, and they told me that the logic board replacement was going to be covered by Apple/Nvidia, the Apple's Quality Program E1. One week later I had it back and running.
On March 05, sadly, the same thing happened with my MBPro 4.1, model A1260. Although this time there was no chime on boot, only the blank screen with the superdrive and hard disk noise plus the lid light on when I powered it on. My Applecare expired last year (It was pretty much useless for me). So I brought it to another AASP in Madrid and they refused to accept it as the Nvidia GPU issue, stating that it was related to the logic board/graphic board, but not related to the article TS2377. Their decision to refuse it was based on the fact that they were not able to run the Nvidia GPU Diagnostic test and hence there was no error code to report to Apple/Nvidia. The price for the Logic Board replacement plus labor and tax: 597,00 EUR. I refused to pay for the fix and took it back.
What I pretty much understand is that Nvidia 8600GT GPU is onboard, it is part of the logic board, and I doubt that the USB Nvidia GPU test is flawless on diagnosing all the Nvidia related cases (TS23277). If you have no chime on boot, they can't even run the NVidia USB test and so they simply assume it's a logic board issue. Beside Nvidia GPU rests the Intel Core 2 Duo processor. Neither the CPU nor the GPU can be replaced easily on the logic board. I doubt that most of the AASP can point out precisely where in the logic board resides the problem if the Nvidia GPU did not cause it. They simply refuse it and state that a LB replacement is the only way to fix it. It's definitely not my problem if Apple/AASP can't diagnose/fix it properly, specially when the problem is already very well known by Apple and Nvidia.
I didn't give up and took it to an Apple Store in Madrid, on March 9, 2012. A really friendly "Genius" lady tried, to run the Nvidia USB test twice and after she was convinced it wasn't booting properly she took it and told me they were going to fix it (replace the logic board) at no cost, under the "Quality Program E1". After two weeks I got it back up and running. After some effort from my side, I cant complain
Apple solved it. Sadly, for the guy on this post, it wasn't easy, it was UGLY, inelegant and scary
It wasn't easy also for people that decided to cook their books (link below).
It is frustrating to pay 3900 EUR for two Macbooks Pro that both will only last for 3 years
3 years? Is it a coincidence or a planned durability policy? Six months ago, just before the second MBP Nvidia fail, I bought a new MB Air 13", equipped with the intel i7 / 256GB SSD / 4GB Ram, as a gift to my wife and I was expecting it to last for at least 4 to 5 years, even if I plan to buy her a new one within the next 2 or 3 years. Dont know how long it will last though. I still have two PCs running Linux (Fedora 14 and Debian), since 2006, which are lasting for almost 6 years, flawlessly. I didn't mention the small issues I was able to address myself... 85W MBP power supplier cord fraying... One Superdrive substitution under warranty (MBP A1226), I/O left board failure (it leads to no sound, no Wi-Fi and no led lights for the screen)...
I am waiting for the new model releases of the macbook pro and iMac. However, ironically, it is time to start thinking different. I am still a big fan of Apple computers, but I know I have other options and alternatives too and Im sure I can make them work pretty well for me. I'm carefully considering what are going to be my next laptop and desktop computers. MBP/iMac or PC Linux.
Further info I collected when I was having problems to make AASP recognize the issue:
