Right.  I discovered that my (old) Lenovo laptop would overheat when I had it 
om my *lap*.  What has happening was when on my lap, my legs would block the 
intake vents.  If the laptop was on a hard surface (eg a table), there were 
rubber "feet" which would insure an air space under the laptop.  I guess it 
was a less then optimal design for a *laptop*... :-)
