Why does my Macbook Pro screen go black when the charger is plugged in while using bootcamp?

While on bootcamp, my computer runs perfectly fine unless I have the charger plugged in. Once I plug it in the screen goes black and starts to charge. I know the computer is still on because I can hear audio from videos if one is playing while I plug in the charger. Once I unplug it the screen comes back on. This makes it so I am unable to work on my computer with the charger plugged in. This is a new problem and did not start once I installed windows 7, it used to work fine. Any suggestions?

MacBook Pro, OS X Mavericks (10.9.2)

I have the opposite problem. As soon as I remove the charging cable, the screen goes black. After finding this post, I was able to get display back using the brightness buttons. I have a Macbook Pro late 2016 with a fresh bootcamp install from last night. I did not set the machine to darken on cable removal. In fact, I saw the battery power brightness setting was left at the default around 40%. I have no idea why suddenly i get a black screen when the charging cable is disconnected.

I also just experienced an absence of mouse pointer on boot up. The trackpad is working, but no pointer. Reboot solved the issue.

I am also seeing rapid battery drain and a clock that has gone out of sync since last night by over 3 hours. For a machine that is only a few days old, I concerned I have a defect or this generation is not ready for prime time. I hate to say it, but I am considering returning this machine since it doesn't seem stable. The reason I bought this machine is to overcome a swelling battery in a macbook pro late 2013. Even as I type this on the new machine, the brightness is up and down...

Such beautiful hardware, but useless if so unreliable.

The tbMBPs have 'teething' issues with Bootcamp. OS X is the primary focus for Apple, while BC/Windows is best-effort.

I have stuck to a 2013 rMBP. Battery swelling issues are much cheaper to address with a new battery, instead o a whole new Mac.

Does the screen come back if you touch a key or the mouse/trackpad?

It does! After hitting the space bar, multiple keys and the trackpad, I thought why not try the brightness buttons and it came back....it's like the setting with the charger in was 0% brightness...I never thought to try that because my screen is normally 75-100% and I had no idea there were multiple settings for plugged in/not plugged in. Thank you!

If you have the Bootcamp drivers installed on the Windows side, the brightness buttons should work as they do on the OSX side. Glad to see it work.

Thank you for your suggestion! It helped me with this issue as well. My problem was that I was that Windows had started but wasn't logged in yet--the brightness keys didn't work on the windows login screen. I had to log in to Windows, then plug in the power, then turn the brightness up.

Thanks again for the suggestion!

In my case, battery swelling is not cheaper to address given it involves loss of an important business machine for a week.

Rapid Battery drain can be due to Power Options. Check the settings for Maximum and Minimum CPU on battery and power. Do the TimeZones in OS X and Windows have the same settings?
