I did have this issue a couple of minutes ago after leaving my thin asus laptop shut with something over it for a couple days while I was out. Miraculously, '''I was able to fix this by applying pressure using my thumb against the other side of the screen on what I thought was the center of the ring''' before that I applied some pressure to the actual screen in the center of the bubble too if it doesn't work the first time. Maybe my case wasn't so severe if it doesn't work for you but the ring was brighter than the rest of the screen and at least an inch wide. Best of Luck!
(This is a pic of someone else doing what I did but I did it on the center of the ring and tried both sides!)
