We, the undersigned, request that Apple Computer, Inc. officially acknowlege the defective NVidia GPU (models 8400M and 8600M) shipped with MacBook Pros (models from June 2007 and Feb. 2008). The faulty chips causes the complete failure of the GPU, resulting in a blank screen.

Since the defect seems to return even replacing the logic board, its clear that NVidia continues do make faulty GPU chips. Giving us only a short term solution.

We believe that Apple should support us, providing free repair and extending the warranty.
