I have a new laptop with an air vent with what looks to be a piece of plastic or tape that is stuck against it on the inside.
Is this a manufacturing mistake? Should it safe to remove by either opening laptop and removing it or piercing it with something sharp? Or is this deliberate from the manufacturers? Can it be that this somehow improves airflow to other parts of the laptop?
I have a Lenovo G50 and couldn't find anything about this regarding that model.
Note the left side one can see a grill under the vent. The right side is smooth shiny black plastic underneath. It is quite hard.
