Q: My screen went black

Greetings JoopR,

After reviewing your post, it sounds like the screen on the MacBook Air is black. Does the computer turn on and have a black screen? Does the computer not turn on? I would recommend that you read these articles, they may be helpful in troubleshooting your issue.
