Apple said some of its more recent MacBook Pro models may contain faulty Nvidia graphics chips that produce distorted video or fail completely.

Among the models affected are those that were manufactured between approximately May 2007 and September 2008. They include the MacBook Pro (15-Inch, 2.4/2.2GHz), MacBook Pro (17-Inch, 2.4GHz), and MacBook Pro (Early 2008).

“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,” Apple said.
