Exploding laptops explained:
Heres how this stuff happens... In the above example, if you notice the table cloths, I think they are that nylon material. Laptops have intake openings on the bottom of the thing (makes tons of sense right??) and the exhaust vents are on the side by the processor and by the memory. The batteries however do not have any form of heatsink or cooling device, they simply are exposed to open air. So anyway, in a situation like the one above, the nylong got sucked up by the intake vents on the bottom, thus suffocating the laptop, and all the fans could do is circulate the hot ass air around. Once a battery gets hot enough, it expands... if its a lot of heat and not much room for expansion... kaboom.
A friend of my ex-girlfriend had her laptop explode while she was using it on her bed. It was an apple ibook, and they had a recall on the batteries for this reason. Needless to say, it got so hot being on her body and in bed, that it blew up, and hot melted plastic nailed her on the neck and face, and had to go to the hospital. She was fine though.
They should really warn people about laptops, because they need some serious cooling or else this sort of thing will happen. Oh well.. sucks for that guy... at least his data should be fine. The hard drives are usually alright in these situations.
