Just stuff in my head

I haven't used my laptop without my external TV screen for since May or June 2023, almost 3 years ago when I came back home from Turkey. Today I bought my laptop with me to my grandma's because I'm expecting an interview and I'm using it without anything attached to it. There's a weird spot in the middle of the screen 🤔 plus a white dotted line on the right side he really needs to retire and lay to rest after a long life of loyalty, 9 years!
