Hello,
So I had to change my yoga 3 pro screen myself after the service centre here failed to help.
Everything seemed ok until I flipped it to 360 (to be tablet-like); it was put on sleep. I found out that it's put to sleep when flipped to 360 and not when the lid is closed. 
I'm not sure what could have gone wrong to have caused this.

Please advise!
Thanks,

Aya
