Replace nvidia GPU on Penryn MBP ?

    I still have a 2008 Penryn MBP that most likely fell victim to the batch of faulty GPUs. Unfortunately the MBP was a few months out of the 3 year apple care period when it started showing graphical artefacts and the random freezing, so I set it aside. At some point I realized that apple extended the replacement policy for these issues - unfortunately, again only just a few months after that program had stopped.

    As I would hate throwing away a good piece of engineering and a (presumably) otherwise fine computer (battery needs replacement as well ofc.), what are the odds of fixing the GPU?

    I have read about people baking their books to the effect of rebonding brittle solder joints. In many cases to no or only temporary success. So that is not something I would pursue.

    Then, there are online services offering repairs (in Germany) that have received less than stellar reviews (people not getting their stuff back, getting it back without problem resolution, fighting over money ...)

    Does anyone know of a solid option on getting this brick repaired? Preferably in Europe/Germany?

    If it is not possible to repait it, what are the chances of salvaging components? I really do not want to turn this thing into material waste, even if the cost effective solution would be to dump it and get a replacement.

    Thanks.

    I think your best bet is to try to find the same model with a busted display, then the salvage the motherboard from it to put in yours.

    Then you know approximately what it is worth.

    What country are you in? Depending on where you are you may have laws that protect you beyond the warranty period. For example, in the UK, and presumably the rest of the EU, Apple are now having to state that sales regulations mean that you will receive free repairs (up to six years in the UK, excluding Scotland) if the machine as not performed to expectations. It would be worth checking out the consumer laws where you bought the machine.

    Also, try speaking with Apple. While you may be out of warranty they'll be aware of the issue and the fact that it isn't an end user caused problem. They may be reasonable and offer a repair.

    Not possible to replace GPU itself, the whole Logic Board needs replacing.

    I had a similar issue, but thanks to God Apple replaced for free the motherboard... Here is the beginning of my story... :D

    I was going to ask how much you'd take for it, but then I saw the "Germany". My logic board was replaced under warranty. I could use a new(er) keyboard and upper case; it turns out that leaving one in the workshop in winter causes batteries to swell. Who knew? :p

    well ... they sell for about $200 - but I'm not trying to salvage money from this MBP. At that price, it makes financially more sense to keep the brick and leave it sitting on the shelf as a solid reminder for whenever the iWant syndrom sets in.

    Guess I'll try my luck with the apple store and see if they can make a sensible offer for the repair.

    I suppose those chips were just birthed with the board?

    Of course you can replace the GPU itself - you simply need the correct tool for the job.

    What you specific need to look into, is BGA array (de)soldering.

    Try to bake it - I'd be hesitant to buy parts to fix it since it's just a matter of time before it happens again

    You have to be experienced at SMT soldering.
