Hi everyone, please have a look: Running the latest version of OS-X (updated then time machined before running BootCamp Assistant) on my 2012 MacBook Pro 15" What I did: Made sure all the latest (pending) apple system updates were installedFormatted ext HD then created a fresh Time Machine diskFormatted My MACReinstalled OS X from BootCampFormatted USB thumb driveCreated Windows 10 Installer & partitioned drive using BootCamp AssistantInstalled Win 10 under BootCampInstalled Chrome in WindowsBegan installing Malware Bytes in Windows while simultaneously downloading Bit Defender What I expected to happen: Continue my initial Windows setup and configurationgo to bed What happened instead:

  1. Without warning the screen went black. NOTE: I saw a notification come up during this process saying that my Nvidia drivers were now game ready or something, however I was using Windows for at least another 10 - 15 minuets Before the screen when black.
  2. Computer still boots up and I hear the wrong key beep (?) when feeling around (see below) What troubleshooting have I attempted?: RebootPRAM resetSMC ResetConnecting the MagSafe chargerHolding option during boot up, then blindly trying to login to windows and OS X, to try adjusting the screen brightness What results have I seen from my Troubleshooting? (Corresponds to previous section) nothing.. it boots blacknothing.. it boots blackMagSafe changed color brieflyThe first time I attached the MagSafe the screen came back then disappeared. (Estimate less than a minute)The aforementioned beeping noises when touching non F# keys… and still nothing Addition Info Someone on another site said that I have a bad Nvidia driver… I don’t know what that means exactly nor can I imagine how to begin to fix it when I can’t see anything. (Tried asking the person but they aren’t replying) Were they correct?If yes what do I do?If no what could the problem be? I would be grateful for any help that you can provide… Thank you

When I hear in the same sentence Macbook Pro i7 and black screen my mind goes straight to fried discrete Gpu, but I hope this is not the case. Drivers get loaded during booting process, do not just get stuck into the Gpu, thus the bad driver idea can probably be discarded for good. Try booting keeping the Alt key pressed..that should take you to the window listing boot partitions available. If you get your screen back it’s probably just a software issue. In case the screen stays black try shining a strong light to the screen and try to see if you got an image but no backlight. In case it’s not a backlight issue try opening the mac and with care and battery disconnected try reseating the Lcd connector and check if you see signs of burns on connector or logic board. If none of these change the situation try reporting back, hopefully someone’s got further ideas but I would vote for a dead Gpu in that case.

For my MBPR 2012 just connect a secondary screen with HDMI and Windows 10 is there on the secondary screen. Then » Setting->Display->Change brightness for the built-in display (higher) Then the built-in display is working now
