We are sure you would have heard of a notebook exploding by now. Here's a a video sent to us by a fellow geek, which shows how a hot a Toshiba laptop got after running for a few hours. The laptop goes hot as 102-degrees!!!!
The message is loud and clear. Don't keep your 'laptop' on the laptop; and if you must use a cooling pad or maybe a heavy jeans and enough padding at the right places;)
