First of all, to be more specific in the word or term " laptop ".....
When IBM came out with the Thinkpad, they said it was small enough to let it sit on your lap. Hence the word " laptop "......
Nowhere in the computer industry states that your "laptop" was made to sit on your lap while you work.
Ever tried sitting on a chair and working on your laptop sitting on your lap for 2 hours + ? Doesn't feel comfortable yeah?
Where do i get this info? I don't know, maybe my 30+ years being in the computer industry in both manufacture and design of computers and notebook. Maybe the fact that I used to be a computer instructor back in the 90's.
In any event, the main topic was the orginal poster's comments of his laptop is getting hot.
Why don't we help try to solve that issue instead of getting off track.
Beter yet, why don't you read sig's comments " Chapter 5 - Safety Information "
Just my .02 cents.
