Great news (sorry if posted somewhere else, but I'm excited) Apple has issued an statement acknowledging problems with the nVidia GPUs used in the SR MBPs - repairs for affected products will be carried out for free, and any repairs paid for will be refunded. Now, I got my MBP back from repairs for this reason.. and when I turn it on or shut it down.. I get a DOS like code (startup, checking machine, etc) How do I turn that off and go to normal booting? Here's the text from Apple regarding the issue: Symptoms In July 2008, NVIDIA publicly acknowledged a higher than normal failure rate for some of their graphics processors due to a packaging defect. At that same time, NVIDIA assured Apple that Mac computers with these graphics processors were not affected. However, after an Apple-led investigation, Apple has determined that some MacBook Pro computers with the NVIDIA GeForce 8600M GT graphics processor may be affected. If the NVIDIA graphics processor in your MacBook Pro has failed, or fails within two years of the original date of purchase, a repair will be done free of charge, even if your MacBook Pro is out of warranty. What to look for: Distorted or scrambled video on the computer screen No video on the computer screen (or external display) even though the computer is on Specific products affected: MacBook Pro 15-inch and 17-inch models with NVIDIA GeForce 8600M GT graphics processors MacBook Pro (17-Inch, 2.4GHz) MacBook Pro (15-Inch, 2.4/2.2GHz) MacBook Pro (Early 2008) These computers were manufactured between approximately May 2007 and September 2008 Products Affected MacBook Pro, models with NVIDIA GeForce 8600M GT graphics processors Resolution If your MacBook Pro is exhibiting any of the symptoms listed above, please take it to an Apple Retail Store or an Apple Authorized Service Provider (AASP) for evaluation, or call your local Apple Contact Center.
