No, it's just that the backlight is at the bottom of the screen and the 
CPU and its cooling air intakes are at the top of the keyboard.
When the lid is closed, the air intake ports suck in the air pre-warmed 
by the backlight. Obviously, the designers didn't imagine that a 
software bug would prevent backlight from working.

As I mentioned, when the backlight turns off by the BIOS, laptop gets 
quite cool.
