who knows about this not just dell laptop's Apple, Lenovo, and HP. So how big is this really?

Question

with which Dell is cooperating. As it turns out, the same battery model is used by Apple, Lenovo, and HP. So how big is this really?

Dell and Sony traced the problem to a flaw in a particular batch of Li-Ion batteries from Sony, which contained microscopic metal particles. Those particles can, in some circumstances, move from one area of a battery cell to another, causing a short or, in rare cases, a fire, said Rick Clancy, a spokesman for Sony Electronics.

Dell competitors such as HP, and even Sony itself, say their customers are safe, even though their products use the same Sony Li-Ion cells.

Answer 1

It only affects certain models. If you think your computer is affected go to the manufacturer's website to see if your battery model is on the list. If it isn't you're ok. If it is...do whatever course of action is suggested.
A fire from a Li-Po battery is not a rare case. It's more the norm than most computer techs are willing to admit to. In an absolute worst case your laptop will catch on fire, taking your house with it.
