MacBook Pro 2012 broken GPU fix

I have a 17" 2011 MacBook Pro that suffers from the notorious GPU video failure (https://www.bit-tech.net/news/tech/laptops/apple-admits-gpu-design-flaw/1/)

Here is the work-around to turn off the GPU. Credit to PeytonPlaysMc

  1. Boot into Recovery Mode
    For High Sierra 10.13.4 or earlier:
    Hold Command+R+S keyboard buttons while pressing the power button

    For High Sierra 10.13.5 or later:
    Command+R+S (Recovery mode Single-user) no longer works.
