Chosen Solution

Hi, I’m having a problem with my MacBook Pro 17” 2011 with faulty GPU. I tried to set the NVRAM variable and delete the AMDRadeaonX3000.kext file, the procedure worked well on my Early 2011 MacBook Pro but it did not work well on the late 2011. When I set the NVRAM variable the late 2011 screen go black and stays black until I reset the PRAM settings (ctrl+cmd+p+r), so cannot disable the dedicated GPU. BTW I have disabled the GPU of many MacBook Pro’s as described in Mac Rumors and the procedure worked flawlessly. However with this particular Mac the screen goes black when I enter the single user mode and set the NVRAM variable: NVRAM fa4ce28d-b62f-4c99-9cc3-6815686e30f9:gpu-power-prefs=%01%00%00%00 Do you know where the problem can come from? Why my screen goes black when I set the NVRAM variable to Intergraded GPU (%01%00%00%00) Can anyone help me with that? I did not find anything about on the net Thanks

The approach you are applying is not workable on the 17” models as they are using a different logic design than the 15” models. The 17” models also don’t have the same board layout. Unlike the 15” models the GPU is located away from the CPU so overheating is less of a risk.
