    DHL returned my MacBook Pro today and everything is working nicely again. How long that remains true, only time will tell.

    Here is the new information from About This Mac:

    GeForce 8600M GT:

    Chipset Model: GeForce 8600M GT
    Type: Display
    Bus: PCIe
    PCIe Lane Width: x16
    VRAM (Total): 128 MB
    Vendor: NVIDIA (0x10de)
    Device ID: 0x0407
    Revision ID: 0x00a1
    ROM Revision: 3175

    None of that means much tome and I don't know what it looked like before the display quit working last Wednesday.

    Hey there,

    just wanted to ask if someone knows whether or not it is possible to buy AppleCare within the warranty extension. 1 Year warranty is over, warranty extension has been granted.

    Asking since it might be possible that a LB-replacement will not solve the issue for good..

    I had the same problem last week. I shutdown my computer before leaving for vacations. We stopped in a motel at night and had free wifi so I tried to boot the macbook pro (17in 2.4 HD screen) and it would boot but with black screen. Tried resetting PMU, PRAM, safe boot, leopard dvd boot, etc... none of that worked.

    I left the machine for repair at an apple certified repair shop yesterday. Hope Apple has a new part that will not fail in 8 months... though I have apple care up to 2010.

    Shop called yesterday: Motherboard will be changed!

    After ten days I received my MPB back from repair. Logic board had been replaced due to faulty Nvidia graphics. The computer worked normally for two hours then it display suddenly blackened again. However, this time nothing worked (no sound whatsoever when pressing start button), indicating that something else than the graphic chip failed.

    I wonder if this was due to a badly seated logic board or if the new logic board was faulty?

    hi all,

    same problem here. macbook pro went to sleep a couple of weeks ago and the display won't wake up. took it to a mac genius and he tried to plug it into external monitor but no luck there either. they diagnosed it needed a new logic board.

    the computer is 14 months old and out of warranty so the store is refusing to repair it - they said there were signs of accidental damage and that i must have dropped it - load of crap! said i should have got apple care.

    everything else on the computer works fine. mac genius said he hadn't heard of any issue with graphics chips in pros but said it was most likely the graphics chip at fault although he couldn't be 100% sure.

    have had to write to apple HQ and demand a refund or i'll be taking them to small claims court. will let you know how i get on.

    everyone please put your stories on here about graphics chip failures and if you've taken them in and what you've been told it will help with my case. my macbook cost £1450 ($3000) and i'm left with nothing.

    The Blank Screen appeared also here. Nearly 3 Weeks out of warranty. It is repaired now on fair trading. And the MBP works fine for a further year? The same logic board, the same play in one year and 3 weeks ...

    Just found an article saying that Nvidia had recognized that some of their chip had a problem... and that Dell and HP has reported many of their laptop users have sent their computer for repairs related to that problem...

    http://news.softpedia.com/news/NVIDIA-Faulty-Chips-Reported-on-MacBook-Pros-As-W ell-91707.shtml

    It also says that Apple as of yet have not acknowledged that there was a problem with their computers with that chip... Hope they will soon for those without warranty anymore

    Dell has made the first step and they offer a 12 months limited warranty extension to all worlwide affected computers with the nvidia chipset

    Apple, what are you waiting for?



    I'd guess it would be signs of the problem genuinely occurring amongst a significant number of people appearing in their own service centres, hec spec. I doubt that anything else really counts for much. Hard data counts for far more than a thread or two on a discussion board, I'm sure.

    Though perhaps a rather more "normal" set of posts on such matters in places like this than the truly bizarre number of first and second time posters from a range of places almost never before seen on the Mac boards might get them a little more interested, and a little less suspicious that some people here might just be having some fun staging a "beat up".

    Then again, maybe this issue specifically affects new users from remote places. A remarkably similar "issue" (though this ultimately proved to be a load of nonsense), appeared with respect to international PB12 screens a year or so back. Again, almost exclusively people from remote places seemed to be affected. Again, those posting about their problems were almost invariably first or second time users.

    Perhaps it is time for a new shipping box?

    I might add that I am sure that some posters here, even those appearing for the first time, are genuine. Things go wrong with computers from time to time. A "blank screen" is far from an uncommon symptom. It can even be caused by a corrupted "wake from sleep" image when your battery goes flat. It can also be caused by anything from a dead PMS to a dead motherboard to a dead hard drive, and, in some cases no doubt, to a dead graphics chip.

    But lets get real about this. Sure, we know that Dell and HP have real problems with their implementation of thermal control of the NVidia 8600 ( and that they have had to put revised systems in place to deal with the matter. We also know that MBPs run these chips at substantially lower temps, just like Lenovo and some other "up market" manufacturers.

    I have just as much invested in my MBP as anyone else out there. I paid for it out of my own pocket, and the price wasn't insignificant (though , contrary to some people's comments and the general mythology of the market place, a little cheaper than quite a few other "upmarket PC notebooks" with similar specs out there).

    I've been using Macs for , literally, decades. Since 1986. When things genuinely go wrong my experience has been that in almost all cases they fix it. I've spent less than $500AU total on all repairs to ALL the many macs I've owned over that period.

    So, "Apple, what are you waiting for?"

    If anything, I'd guess a large part of it would still be something a little less ephemeral, and genuinely demonstrated in the hard numbers coming into their repair shops, to deal with.

    Cheers

    Ah yes, there I return again to add my quibbles to the ongoing discussion. I'm living in Germany by the way. After having taken my Macbook Pro to a certified provider for repairs, it turns out, they believed it was the harddrive causing the screen to remain black, although the computer would start up normal. I can log in and turn on voice over and navigate as normal. When the screen does goes on (sometimes is does, sometimes it doesn't) the mac runs as usual (without problems).

    I had arranged with Apple Care that the needed part would be sent free of charge, even though my Warranty is a couple weeks over due. The tech at the store had already ordered a new hardrive from apple, then decided to sent the new harddrive back to Apple (can't say I've ever heard of a harddrive problem that only affects the monitor while leaving all other processes untouched).

    A solution has not yet been found. Presumably, the mainboard will be replaced (which I had mentioned to the tech guy as being my assumption of the problem). This was the case about half a year ago, when my macbook pro was sent to apple because of the same issue. The motherboard was replaced then also.

    Because of his mistake, I will now have to beg Apple again to give me another break and cover the part. Even though this is the same problem.

    Either way, this has caused me to lose much time dealing with this. Our company has all macs and has always used macs without major problems. I now have to move to my pc(the only one here) and work there. Actually not a bad experience atm.....hm...maybe I'll go back to Windows in the future.

    Rod,
    maybe it's because people from +remote places+ can't easily walk into the next Apple store to get the feeling of being taken care of?
    I had a very hard time to convince the tech guy at my Apple authorized repair shop to take a look at system profiler reports and system logs from the past 6 months to see that there's a pattern of GPU problems going back to the day I bought the MBP, 1 year + a few weeks ago.

    Almost a dozen of my friends and family changed from a PC to a MBP in the past 12 or so months alone. It would never come to my mind to judge their credibility by the number of previous posts in a english language forum.

    I've seen things go wrong with Mac's for 20 years but rarely within such a short period of time with the exact same symptoms. Fortunately I didn't pay for my computer in the first place, my company did. I also had the incredible luck to get the first logic board replaced for free and #2 & #3 failed just days after having been installed.

    Today I will pick up my computer with logic board #4 and hope for the best.
    Unless the replacement board has a GPU from another batch I know what is going to happen within days. If there was an alternative GPU available for the top range model I would have bought it 3 weeks ago.

    Next week I will travel from remote Vienna to less remote London and walk into Apple store to see if they got any ideas how to prolong the life of the GPU or if I should get a desktop with proper thermal management instead.


    cheers

    And for the records in case anyone wants to compare:

    logic board #4 has:
    Boot ROM Version: MBP31.0070.B05
    SMC Version: 1.18f4

    Obviously Software Update was quick to point out that there's a newer firmware available.
    Unless Apple comes forward with detailed information what EFI Firmware 1.5.1 actually does better I refuse to install it until right before the 90 day service warranty is over.

    cheers

    As with everyone else in this topic, the same thing has happened to me. Three weeks out of warranty, the graphics chip fault arises. I went to the Apple Store way out on the east side of my county and at first the Genius said I shouldn't rely on the Apple Forums, a lot of people post things that aren't true very often. I kind of laughed and told him how interesting it was that this topic has recieved a lot of attention lately. He also said he has seen like 1-2 cases before mine as well.

    Unfortunately he was not nice enough to grant the replacement for free or anything, so I have to spend $350 to send it out. Much like everyone else has. Now let's see, is this going to be another ticking time bomb. How long do I have before this one goes? Apple is really having issues recognizing this problem. Wake up and help the customers and products you're supposed to stand behind.

    Anyways the Genius also told me that if I had it done at the store, it would cost me $1,200. But, if I sent it out it would only be $350. Which baffles me.

    He said it looked in "pretty good" shape. It's actually in great shape, I barely bring it anywhere and I clean it once a week. And I told him as soon as I got there that I thought it was the graphics card. And he said he "highly doubted" it would be that because I was relying on the forums.

    Interestingly enough, he later said I was right and that it is the graphics card.

    They really irritate me there, they like to dumb down there customers when we actually know what the issue is.

    Well we'll see how many times I get to replace a graphics card now. I can't wait.

    Final update (I hope).

    Just got my MacBook Pro back after sending it in for very expensive repairs... just outside the warranty period. New logic board + installation for around $1400 CDN. I'm hoping to get reimbursed through my credit card company which offers an additional 1-year extension on the warranty of most purchases.

    The Apple phone guys seemed quite understanding, especially after I noted this thread and several articles, including one indicating that Dell is extending their warranties for problems related to the NVIDIA GeForce 8600M card (http://www.electronista.com/articles/08/08/08/dell.expands.gpu.fail.list). Of course, they weren't so understanding as to take care of this under warranty!

    The computer seems to be working so far, but I do believe Apple should be taking better care of its customers...

    We've got two MacBook Pro's--one purchased June 2007 and the other the end of July 2007. The June model went screen blank two weeks ago-- off warranty, but new motherboard provided at no cost at genius bar. Purchased extended warranty for the second computer for $350. Same symptoms: no video, computer running (could play iTunes using Quicksilver commands, etc.) -- followed all procedures resetting and starting from CD--nothing. After the genius approved the no cost repair without any problem, I showed him a couple of web articles on the NVIDIA issues. I'd like to see a long-term (3 years minimum) automatic fix for this issue at no cost.
