Does a reliable GPU diagnostic test exist for the well known defect?
I'm a repair tech and I encounter many problems with Mid 2010 MacBook Pro 15" laptops. I'm aware of the defect with the graphics processors for this release (TS4088), but I don't have a way to determine if a laptop is having the issue for sure.
I can't seem to reproduce a kernel crash reliably and Apple Service Diagnostic won't even catch the problem. I've also tried third party GPU diagnostic software, but still no luck.
I've read that Apple developed a custom diagnostic called Video System Test to test for this issue but can't seem to find it anywhere. Has anyone figured out a method of reliably testing for the graphics processor failure in this model?
Is dit een goede vraag?
