Today the weirdest thing happened, I sat down to use my laptop and the screen flipped itself upside down. This was kind of funny but I like to do things right side up. You can easily fix this with Ctrl + Alt and the up key. But for me, today my screen keep flipping on me so I wanted to stop it from being able to do it again. I opened the charm bar and clicked the screen brightness button and then click the screen to lock it.You can also right lick on the screen and select screen resolution and click on the box for Allow the screen to auto-rotate, then click apply.
