Do not put laptop on lap

[Alex]

Computer batteries can get hot during normal use. Do not use your computer on your lap.

Here's a smashing idea, and one I use on occasion:

If the battery gets too hot for comfort, take it off your lap.

This seems kind of like saying "Roads can become icy, do not drive on roads."

I would think you'd have to have some sort of nerve disorder to not realize you were sustaining burns. I would have taken the thing off my lap before that point.
