Apple have confirmed problem for 8600M GT in Macbook Pro

[Wentworth]

It's pretty far behind the likes of Dell and HP in getting to the bottom of the whole defective NVIDIA GPU situation, but Apple has now finally come out and confirmed that some of its MacBook Pros are indeed affected by the problem. According to a just posted Apple support document, the specific models affected were all made between May 2007 and September 2008, and include all 15- and 17-inch models equipped with NVIDIA GeForce 8600M GT graphics processors. As with other laptops, the problem shows itself in the form of distorted or scrambled video, or a complete absence of video on the screen or external display. If your MacBook Pro falls into that lot, and the problem occurs within two years of your original purchase date, Apple says it'll repair it free of charge, even if it's out of warranty. It's also issuing refunds to folks that have already paid to get their MacBook Pro repaired. Hit up the link below for the complete details.
