Disable dgpu on MacBook Pro late 2011
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
Esta é uma boa pergunta?

Are you able to boot up in Target Disk mode? Hold the T key do you see the FireWire/Thunderbolt port icon?
