Keep in mind that the discrete GPU will free up some system RAM that was reserved for the onboard graphics processor, and will also run faster in general; however, it will also run hotter and cut down battery life by an hour or two. If your system is affected by this problem, you might consider enabling screen sharing in the "Sharing" system preferences, which will allow you to use another Mac to connect to and manage the one with no working display.

Optionally and if you are familiar with SSH and the Terminal, you can enable "Remote Access" in the sharing system preferences. These options will prevent you from needing to do a hard shut-down in the event the screen goes out on you. Have a fix? Post them below or e-mail us!
