This free replacement was announced last year by Apple when it found that MacBooks equipped with GeForce 8600M GT graphics cards had problems with image distortion or no video signals on screen.
At that time, Apple only replaced free for the machines that were used within 2 years from the date of purchase. But now, the company decided to increase this period to 3 years and will replace it for free even if the user no longer holds the warranty.
15-inch or 17-inch MacBook Pro laptops equipped with an Intel Core 2 Duo processor and sold since mid-2007 all run the risk of a graphics card error.
Therefore, Apple recommends that if you encounter any of these problems, you should contact the company for repair and replacement for free. For more detailed information on this issue, users can visit its customer support website.
