As there is on the photo, in Japan during a meeting a notebook takes fire: probably a Dell has explosed for more 5 minutes and maybe a model of bad battery.
Come si vede in foto, in Giappone durante un convegno un portatile ha preso fuoco: probabilmente un Dell è esploso per più di 5 minuti, un modello con una cattva batteria.
[…] Rechargeable batteries are the brawn behind the brains of todays portable electronic devices. Dell said a manufacturing defect in some lithium-ion batteries supplied by Sony caused a handful to smolder and catch fire, and it advised owners of affected computers to run them on wall current until replacement batteries arrived. Rechargeable batteries come in two popular types. Lithium-ion batteries are generally found in laptops, cellphones and iPods; nickel metal hydride (NiMH) batteries are used in cordless phones and less-expensive digital cameras, plus a few laptops. Lithium-ion batteries are particularly sensitive to heat. To avoid the danger of a fire, they should not be stored in places that get direct sunlight. Many manufacturers specify a temperature range for operation. In addition, the connectors should be kept away from metals that could cause a short circuit. There are a way to increase the life of a rechargeable battery: one of the best strategies to prolong battery life is to use them. Otherwise, they will lose their capacity to hold a charge but continually keeping a laptops lithium-ion battery at full capacity also reduces the batterys ability to live a long life. A laptop continues to draw battery power when it is put to sleep; it is necessary to shut down the computer completely for cut back on power consumption. To reduce battery consumption further, both the Windows and Mac operating systems include control panels that allow users to increase battery life by simultaneously decreasing performance: in a Mac, there is Energy Saver pane in System Preferences. On a Windows laptop, choose the Performance and Maintenance tab in the Control Panel icon, which is found under the Start menu. Other battery-saving strategies include removing a CD or DVD from the laptops slot when not in use to prevent the disk drive from needlessly spinning, and quitting any applications not currently in use: this is true also for maximizing an iPods battery life. The Soldius1 Universal Solar Charger ($110) can power up an iPod, cellphone, or P.D.A. in less than three hours, using only the suns rays. On purpose of Apple it was recalling 1.8 million batteries from some models of its laptop computers because of a risk that they could overheat and catch fire: do you remember ? Batteries were made by a unit of Sony, which also made the 4.1 million laptop batteries that Dell recalled last week. […]
