Assuming you mean the bit highlighted in the picture below? This is a port to connect to a docking station, something like this.Can you please answer the question I raised in Post #1, which is what is the rectangular metal encased insert on the back cover? I quote, "However one thing I ascertained was that the focus of the heating through the back cover appeared to be an elongated rectangular insert which looked much like a socket (but wasn't) and was surrounded by a metal casing. You could tell it wasn't a socket as it had no holes to plug anything into. It lies towards the same corner of the laptop where the inlet and outlet of the fan are located."
Assuming the issue is due to dust blocking the vents, even partially. The air gets hotter than it would normally because it can't be expelled from the case efficiently. It circulates around inside the case longer than normal and picks up more heat from the CPU and associated heat sink rather than being pushed straight out of the case.Okay, so the dust clogging would cause the fans to run continually and faster to compensate. But what is causing the air to become so hot in the first place? I can feel a significant airflow caused by the fan.
But why is the air coming out of the fan so hot?
Under normal circumstances when it is clean the fan doesn't need to work so hard (so you dont feel so much air) and that air will be cooler as it is able to pushed out of the laptop quickly and efficiently.
