Take the optimistic view of the choice of demonstration laptops. Maybe they chose a Lenovo because they wanted something that they though would be safe enough to use for a demonstration of blocked ventilation openings. There is little information available at this time. Mr. Woodgate is correct

I don't believe it. Yes, a notebook computer will get hot with the vents blocked. Will it generate enough heat to ignite clothing it is resting on? I highly doubt it. According to this website: http://www.tcforensic.com.au/docs/article10.html Cotton ignites at 250 degrees C (for some reason

I agree with Ted, John, and Scott. Cotton doesn't self-ignite from heat alone unless the heat is applied quite quickly, before the cotton chars. In many cases, ignition of cotton requires a flame. Charred cotton doesn't burn. The Handbook of Physical Testing gives cotton ignition temperature as

No computer I've met will ever heat up to the ignition point of any practicle material. Far too many different thermal shut offs. But some cheep knockoff might can find a way around the built-in thermal protections of the usual computers... I'm picturing these $100 dollar computers for everybody
