It wasn’t long ago that some NVIDIA notebook GPUs began failing that were used in many notebook computers from Dell and Apple among others. The GPU failures ultimately led to a lawsuit being filed against NVIDIA by some affected notebook owners.

A number of threads on the Apple support site are reporting new graphics errors on new 17-inch MacBook Pro notebooks that feature NVIDIA 9400M and 9600M GPUs. According to reports, the notebook graphics are fine as long as only the 9400m is used.

However, when more power is needed and the 9600M GPU kicks in there are noticeable graphics problems that get worse as the GPU heats up. The problem manifests in green lines that appear all over the screen. More than one user is having the same exact issue, even on new notebooks. The error appears to be limited solely to the 9600M GPU. At this point, if a replacement is needed for the GPU or a firmware fix will suffice is unknown.
