Laptop batteries overheating is nothing new. This has been been happening to various computers for well over a decade, but that doesn't make the periodic recalls any less terrifying. After all, this is a device that literally goes on your lap. Sony had to recall more than 1,700 VAIO laptop computer battery packs last June because of fire hazards.
Advice on dealing with a bulging, hissing or overheating lithium-ion battery varies, but the educational site Battery University sponsored by Cadex Electronics suggests moving it away from flammables, ideally outside. Avoid touching a smoking or flaming device. For a small electronics fire, use a foam extinguisher. Credit: Stewart Butterfield, Flickr Creative Commons
