PS. I haven't closed my laptop. (this is how I used my previous laptop)

Turing off screensaver has solved it. Updated Start screensaver when active to "Never"

To increase the lifespan of you laptop, I suggest closing it. If you're still facing the problem, you might have a defective laptop. I suggest contacting the apple support.
