I RMA'ed the unit last week, and got it back today.
The screen was replaced. The new screen however, has a max resolution of 1024x576, while my old screen had a max resolution of 1366x768.
The hinges of the screen now feels like someone has filled them with sand, and the screen will no longer stay in position when it is closed.
Whatever Dell did to my computer, it is far worse now than what it was. I have called the support again and they promised to call me back when they had found out what went wrong.
My poor Mini
