Laptop Batteries: How dangerous can they be?

Where does a notebook knows that with the battery, the one he has used, is technically cope? How to recognize the device, how much power the DELL Studio 1555 battery can still muster, and how many charge cycles it has been brought back in? And when is the best armed and well bekrallte with the latest IT software lap kitten not prevent him from doing to a defective battery crushing violence? The answer to all these questions know those tense manufacturer of battery only too well the feeling in the past too painful to business-damaging Dell Inspiron Mini 9 battery recalls were forced. Including those otherwise blameless sounding names such as Fujitsu, BenQ, Hitachi, or HP. And now it has even caught that also portable fruit, known to the connoisseur of old apple varieties under McIntosh, and all Macianer under Apple. But now what are actually the weak points on the mobile power sources? And the tense wrong fuse can also be dangerous to humans?

If the apple falls far from the tree

If an Apple laptop communicates with its battery, then this principle secret conversation is surprisingly protected only by two measly passwords. This bit of false security can be easily bypassed, as the IT security expert Charlie Miller has found. In experiments with their own equipment, he could easily run an access to the Dell Inspiron 1545 battery controller, and this as it chooses, though certainly not reprogram the purposes of the inventor. Although Miller does not command the battery, to destroy itself in five seconds. Incidentally, no one else that can, as was observed for reassurance. But Miller could make the battery with its malicious code once and for all but completely useless. And in principle it could also ensure that infects the Dell Vostro 1500 battery when infected, and subsequently even fatally ill. The days in which to fear the lack of assets Macianer no hacking needed, are apparently over. Increasing market share can also just have their pitfalls. Since it is quite reassuring to know that Charlie Miller to the "good" one.

Fire hazard

In December 2009, Fujitsu gave his fans an unpleasant surprise pre-Christmas. It had in fact proved DELL Inspiron 1300 battery, Pi2512 Pi2515 thermally and at work were advised to boil more than the safety of operation was appropriate. Or in other words, the things were so hot that it literally caught fire. Clear that these had misdirected fire from the manufacturer sets can be returned and exchanged. This hot iron had incidentally also other battery manufacturers such as Hitachi touch, Apple, Lenovo and Toshiba, for better or worse. The Dell Vostro 1510 battery can then be debated topic really, really flaming. And indeed had prohibited such a fervor that even some airlines to operate on battery powered laptops to security reasons.

Conclusion

From notebook batteries to go from basically two serious dangers. Once the possibility that the Dell Inspiron 1564 Battery is on its built-in microprocessor for malicious code to spin, and thus both itself and the laptop is put to the sword. The other danger is aptly described by fire and flame. As is the normal network operations in doubt, always the safest alternative to lithium-ion Surprise egg.
