1) Yes
2)
3) Occasionally, but usually not
A) Not usually if I don't block the vent
4) Yes
A) No
B) No
-) Usually
-) No
C) Not due to heat or power issues
5) No
A)

I use a laptop cooling pad to keep my laptop from overheating, as such I rarely use it on my lap unless I take it somewhere away from my desk. To keep it cool while gaming/folding/etc I also have some desktop case fans hooked to a 9v transformer that I put behind it to keep it cool.

The problem is that people do not use there brains and there laptops at the same time leaving a laptop with its fan insulated by a duvet/pillow is not a good idea I have managed to get my laptop upto 85C doing that monitoring via speedfan. If the pc is on a desk then my tablet laptop averages 45C and my old laptop 35C.
