As right as that might be, it's on carpet!

I don't believe they put much thought into airflow and overheating...

I can't tell for sure, but it looks like a Lenovo y510p. Or at least it looks very similar to the one I owned back in the day.

There was a vent in the hinge, and these things would absolutely cook themselves with the lid closed

I also have a laptop working as a server. The problem is that the WiFi antenna is in the lid and it just doesn't work well when the lid is closed
