Hello Everybody

This machine come with kernel panic problem when working graphics or video . I know this machine have GPU issue but extended warranty ended.
Problem is looking like mid 2010 GPU switch problem. When started ASD kernel panic with this report;

Video Controller External: Gmux switch to EG and verifiy (test 4) test will switch display to EG and Verify.

Replaced C8930,C8931,C8943,C8942 but nothing changed.

Do you have any other suggestions before try the video chip?

Nop, apply some heat in the core of the chip (about 180°C)and try again, if it works is time ti replace GPU....
