      I work for Dell, my job is to decide whether to recall. Everywhere I go I apply the formula.

      It's simple arithmetic. If a new laptop built by Dell is sitting on someone's lap, and it bursts into flames, sterilising and disfiguring the user, does Dell initiate a recall?

      You take the population of laptops in the field (A) and multiply it by the probable rate of failure (B), then multiply the result by the average cost of an out-of-court settlement (C).

      A times B times C equals X. That is what it will cost if we don't initiate a recall.

      If X is greater than the cost of a recall, we recall the laptops and no-one gets hurt.

      If X is less than the cost of a recall, then we don't recall.

      Everywhere I go, there's the burned-up wadded-shell of a laptop waiting for me. I know where all the fried testicles are. Consider this my job security.

Suddenly those little settlements become one big settlement for everyone who has your computer.

      Then you have to get someone to do the corral the negative PR that is happening against your company, so you only had 10 reported cases of a machine blowing up, one just wanted to know why it wasn't thought of somewheres before hitting retail and 59 (not doing actual numbers because it would be in the thousands, cause where there is money to be made by doing nothing, people will show up and want a peice of that pie) others want money from your company and you are now out of a job.

      Sure this is just one computer but now the questions will slowly start happening,

      First step: Deny Deny Deny, Your company did nothing wrong.
      Second Step: Claim it was the users fault, They weren't using the proper power supply/battery for the notebook, it's not the companies fault.
      Third Step: Claim it's a small problem, Your company is presented with proof it was their fault it happened so now it's time to claim that it's a small isolated problem and out of the millions you have sold worldwide there is only the one.
      Fourth step: People see the chance to make money, Now you have people coming out claiming it happened to them and naturally they have no proof cause they got rid of the notebook since it "Blew up and no longer worked!" and then a lawyer sees a chance to make a name for him/herself and make some nice change from it. Time to issue a recall on all of them regardless.

      Must have been a pretty catastrophic failure. There are usually at least three levels of protection on any lithium-ion battery:
      • PTC cutoff switch - there's an overtemperature cutoff switch inside each Li-ion cell. If the cell gets too hot, the resettable cutoff switch disconnects the battery from the others. If it gets really, REALLY hot, then that cutoff becomes permanent. This is a last resort protection device, and should NOT be relied on to work. It's there to try and limit damage if everything else fails.
      • Protection circuit - monitors state-of-charge, voltage, temperature and input/output current of the battery. If the battery voltage is too low or too high, or if you try to overcharge or over discharge the pack, the circuit disconnects the battery pack from everything else until the voltage, etc. returns to its normal 'safe' range. If you REALLY piss off the protection circuit, it will literally blow a fuse - most packs are fitted with an "SC-Protector", which is basically a fuse that can be blown by an electrical signal (a "self destruct input" if you will). Not only do you get the overcurrent characteristics of a fuse, you also get to blow it if something bad happens. SC-Protectors are not readily available in quantities less than a thousand or so, so once it's blown your battery pack becomes a brick.
      • Charge controller - the charging circuit should continuously monitor its output, and shut down if it goes out of range. Not all of them do...

      The problem with Li-ion (and to a greater degree, Lithium Polymer) cells is that they're so sensitive - charge them over 4.2V or discharge them below 3.2V and the cell will be damaged. Abuse it a lot and it will blow up. To get that to happen in a properly designed circuit, you'd need a chain of failures:

      • First, the protection circuit would have to fail in some way that would prevent it from protecting the battery pack. A shorted switching transistor (usually a MOSFET) and a dead SC-Protector drive transistor would do that nicely. The protection IC can see something's really, really wrong, but it won't be able to do anything about it. Bear in mind the switching transistor has to handle the power of charging and discharging - it takes quite a beating. Shorted MOSFETs really aren't that rare.
      • Next you'd have to have a failure in the charge circuit that causes the battery to be overcharged. For the sake of argument, let's say the charge IC has latched up. It no longer regulates its output voltage properly and - again, for the sake of argument - we'll say that there's 5V over each cell instead of 4.2V.
      • Now that fault condition has to exist for long enough that the cell electrolyte will break down (usually into hydrogen and other miscellaneous nasties). When that happens, the safety vent will fire and the battery ejects a hot stream of gas.
      • Now the final act. A little spark (say, from the PTC switch) and that hydrogen catches fire. That flame heats up another cell to the point where the vent fires, and you have a second cell joining in the explosive fun. In a few seconds, that cell will set fire to another, and the process will keep on repeating until the cells burn each other out, and the fire runs out of fuel.

      The big problem with Li-ions is that they're inherently unstable. The nickel-based batteries tend to be much more forgiving of abuse. They usually don't blow up unless you really, really abuse them. You might damage them and reduce their capacity a bit, but you usually won't be able to make them explode or spontaneously combust without some serious work. They do have a lower energy density and terminal voltage than Li-ion and Li-Polymer, though, which might partially explain why they're more stable.

    How is it possible that even images of their own device on fire could look so boring. They're so devoid of composition, of sensitivity.

    In this other example, the victim has taken time to place the burning device against a backdrop of roughly hewn rock, and has done so at a time of day deserving of the generous tones cast by the flames as they lash, even swagger about the white plastic..

    Dell, here this: even in death, one should look positively gorgeous.

    A number of the bullets would obviously rupture the aircrafts fragile hull, and as a result of the altitude, the entire plane would begin to depressurise and disintegrate.

    no it wont. popping several holes in a pressurized plane even a window will not destroy or even cause major damage to a plane.

    Anyone into avionics and avaiation knows this as well as mythbusters also proved it. the only way they did any major damage was lots of primercord and shaped explosive charges.

It also established access to metal in China. http://www.newton.dep.anl.gov/askasci/chem03/chem0 3547.htm www.cabrillo.edu/~rroland//CHEM1A/JoshLabManual/11 -HeatofCombustion(Magnesium).doc Bet it was nearly this model: http://laptopmag.com/Review/Dell-Latitude-D620.htm Magnesium, a silvery white metal of atomic weight 24.32, ignites at 632C and burns at 1982C, with magnesium oxide (MgO) as its combustion product. In an exothermic reaction, metallic magnesium can ignite to produce magnesium dihydroxide (ie, Mg(OH)2) and hydrogen. Magnesium is used in either powdered or solid form as an incendiary agent for both illumination and antipersonnel purposes. Various alloys of magnesium (eg, aluminum/zinc/magnesium alloy found in US M126 round) are mechanically sturdier but also can be ignited easily. Thermite is a mixture of powdered or granular aluminum and powdered iron oxide. When combined with other substances, such as binders, the material is termed a "thermate." All such materials react vigorously when heated to the combustion temperature of aluminum. This reaction produces aluminum oxide, elemental iron, and sufficient heat to melt the iron. The reaction temperature is approximately 2200C.

  32. Why the Dell hate? by retro128 · · Score: 3, Interesting

    Man, there's a lot of hate in here for Dell. Just curious, why? My GF and boss both have a Dell 700m and I've got to say those things are solid. Small, light, battery life of 3+ hours. Light years better than Vaios, IMHO. I've experienced few problems with their desktop systems as well.

    As far as the exploding laptop, is it really the manufacturer's fault? This question would apply regardless of who it is. It would seem to me that if it were a manufacturing defect in the laptop, say in the charging circuitry, those models would be exploding left and right. It was very likely that the battery pack on that thing was made by a third party and sold for half the price of an OEM pack.

    That's not to say that OEM battery packs can't blow up. The battery cells are procured from outside manufacturers. Of course, laptop manufacturers will (hopefully) only buy batteries made by reputable firms, but right now there's big business in counterfeit batteries over in China. I remember awhile back Kyocera had phones coming with counterfeit batteries that were exploding in peoples' pockets and hands, inflicting some serious injuries. The thing is, don't just eye Dells with suspicison - I imagine it's possible for any manufacturer to get a bad batch of batteries if they're not careful, but I imagine that's rare and they are, indeed, careful. Big laptop manufacturers probably have direct accounts, anyway.
