don't invest in a product that no one stands behind the quality of
Immediately on restart after updating my OS from 10.5 to 10.7, the screen would not come on. Just stayed black, even though the machine was on, keys worked.
Apple genius claims without any testing or diagnosing under the hood that it is a bad logic board. (Actually he plugged in a hard drive to get the serial of the video card, pretending it was a diagnosis.)
I tried deleting the sleepimage as recommended on the forums. That brought back the screen. Then how is it a hardware problem? Only for some reason the black screen of death returned. So maybe it is a hardware issue that is caused by an unstable driver.
When I asked the Apple genius to explain this, he said that the update must have brought out an existing hidden problem in the GPU. He was careful not to say it was a defective GPU, but that it was an issue my machine is having.
This contradicts Apples statement:
About Mac OS X 10.5.7 Combo Update
The 10.5.7 Update is recommended for all users running Mac OS X Leopard version 10.5 to 10.5.6, and includes general operating system fixes that enhance the stability, compatibility and security of your Mac.
My Macbook Pro is no longer stable as an immediate result of installing the update! But by this reasoning the update should have made it less likely to have brought out an existing issue!
I asked the genius how could i be making screen shots of working software if the logic board had failed? He could only guess it was the GPU, at which point I realized he was willing to tell me a price to fix the machine when he did not actually know what was wrong. He had just told me earlier that the video card was working after plugging in a hard drive to determine if the card was in the specific range of Nvidea's coverage. Wait a minute... THE GPU IS WHERE?
Why did the Apple genius, after telling me the video card was working, tell me that the problem could be in the GPU? The answer is obvious, he does not know. He could not possibly know. He's just following orders. He's not a genius technician. It's all a sham to reduce expensive fixes.
It seems the logic board replacement is a catch all fix at my expense, catching the driver issue or whatever it is by replacing everything under the hood. One should suspect the logic boards are defective, at the rate they are replaced as many of these forums are evidence. And hmmmm... there is a precedence noted in the apple forums of dozens of people getting their logic board fixed free, and a lot of problems eerily similar to mine regarding the Nvidia 8600 chipset which is the same as mine!
Still, the Apple genius claims that my specific Nvidia chip is not covered in the warranty extension! How can the chip manufacturer predict that my chip isnt defective if it did not know there was problem with the specific range they are covering when they sold them??? The logical conclusion is that there are multiple ranges beyond the existing coverage that are also defective! My case should be explored to determine what is wrong, not shoved under the rug at my expense! Remember that this "genius" told me my Nvidea card was fine, and that it was likely a problem within the GPU.
This is a clear case of a defective product or software, and there is a precedence set for free replacement if it is hardware, and yet Apple is so set on profiting from my misfortune that they cannot see how they are shooting themselves in the foot. I will never buy Apple again because they do not stand behind the quality of their product, and I will make sure everyone I know will not make the same mistake. My g3 ibook still works to this day nearly 10 years later. The new stuff no longer "just works"...

it is just an expensive paperweight. I will gladly put money into a product where the manufacturer stands behind the quality... apple may think they saved $300 but word of mouth = tens of thousands in future purchases down the drain. Good luck with your genius tactics Apple.
