Bowie J. Poag writes to mention a page put up to commemorate the explosion of Alan Cox's laptop. From the article: "Alan was on the other side of the room from the laptop. I was elsewhere. He yelled out, I ambled towards the room in my own good time, and then I heard 'Fire! Real fire! Call the fire brigade, now!' and I speeded up a bit. From Alan subsequently, I gather there was an explosion and flying pieces of laptop, and a fireball, and a couple of fires started where (presumably) boiling battery landed, and one fragment smashed an LCD monitor. And then there was smoke and smell (there is still smell) and smoke alarm wailing and firemen and sirens and paramedics (happily unneeded) and police and a man with a notebook asking questions for the fire report.'"
Perhaps he should have considered an Apple or Dell instead.
Or perhaps he should have bought his battery in shrinkwrap from a reputable dealer rather than getting an after-market battery off of eBay? Even if it's a "genuine" IBM, for all he knows he ended up with a recall unit that somehow (*cough*) got resold on the open market.
There are some things you DO NOT trust after-market vendors for. One of those things happens to be a highly explosive Lithium Ion battery pack. There are enough problems with the first party units to give pause to anyone even considering third party units. Getting off of eBay? Now that's just asking for trouble.:-/

The problem is that the "reputable dealers" have ridiculous markups on replacement parts. You can get a digital camera battery for $40 or for $4. For most people the $4 batteries work just the same and don't fail. Actually I am under the impression that more name brand batteries have been the cause of laptop fires than others, perhaps because they are supposed to be the best performing batteries, so they have to cut more corners than generics. One thing which could really help the situation is standardization: It would bring prices down by enabling competition and reducing the number of different battery packs a manufacturer needs to support. That would pretty much eliminate the need or desire to buy off-brand batteries.
Hmm, yes, quite like the Exploding Nokia batteries, indistinguishable from genuine Nokia batteries (according to Nokia), but fake batteries nonetheless (according to Nokia again).
Here's my thoughts: Nokia bought a batch of faulty batteries bud didn't want to admit it. Therefore they said the batteries weren't theirs, even though they coulod not make the distinction.
The real reason you should be buying laptop batteries directly from the manufacturer (or in this case, the vendor: Apple, Dell or IBM) and not a reseller, is that the Li-ion batteries start degrading as soon as they're manufactured due to stresses in the crystal matrix. It does not matter much, therefore, how the batteries are used, for they will only last up to three years before cells will break. Thus, you want the batteries as fresh from the factory as possible, which is why you buy them from the vendor and not a reseller, because the turnover speed at the vendor is greater.
Explosions are quite common to high-capacity batteries. It's the energy, you see.
Think of this as a learning experience If Linux had implemented BeOS's is_computer_on_fire() [tycomsystems.com]* system call, he would have been able to log the situation, send an email to his friend to alert the authorities, and shut down cleanly.
I also very much like the is_computer_on() functioncall, documented on the same page, which returns 1 if your computer is on, otherwise undefined. Very clever.

"What? Exploding laptop and you're running linux? Oh, we don't cover that."
Sorry, but I believe HP has a trademark on that phrase, as I was so exquisitly told by the circuit city folks when I indicated that the HP5320dv I'd just bought would probably have linux on it in less than 48 hours. I picked up the warranty form and said, well, I just guess the lawyers will have to sort that out now won't we? It did get FC5 installed as soon as I could make backups to dvd's, and works great with FC5 on it except for the broadcom radio in it.
In any event, this, because its Alan Cox's machine, may well be the most famous blowup yet.
I don't know what type of battery is in my HP, but its been very well behaved so far. That knocking sound? Thats me, knocking on the wood of the tabletop here.:-)
I got curious about how much better Lithium Ion batteries were than Nickel Metal Hydride. So, here are a few numbers I quickly grabbed from the Wikipedia.
My laptop gets a couple hours of battery life with Li-Ion. It looks like I'd get about 40% of that with NiMH -- not that appealing. I don't think we'll be turning back any time soon.
I just hope that the next generation of battery technolgy is inherently less likely to explode.
For one, keep in mind that it's not a laptop, it's a notebook.
So it's roughly 8.5" x 11" (A4 for the metric world)? Because, you see, the term "notebook" was specifically inaugurated for the subclass of laptops the approximate size of -- get this -- a notebook. With the ones even smalled than that being "subnotebooks".
Laptop is an unfortunate consumer-ism

Question: With all of the exploding batteries lately (Apple, Dell, Toshiba, IBM/Lenovo (possibly), etc. Have you seen any reports of Sony laptops exploding?
Does Sony "cherry-pick" the A-grade batteries for their own use and send the B-grade and lower ones to their clients?
If so, what kind of liability issues does that raise. Sony HAS done some questionable things in the past knowingly.;)
"Sony HAS done some questionable things in the past knowingly.;)"
Riiiiiiiight, sure they have. Do you expect me to believe a multibulliondollar international corporation would be so stupid as to do something as underhanded like distribute under-tested batteries or stealth-installer-rootkits on music CDs? Pfeh. Next thing you'll try and tell me Ford made exploding cars...
With the current trend in battery explosions for laptops, I wonder how long until all laptops are considered explosive devices and aren't allowed to be used on planes. Perhaps we should start using things that are more stable. Like radioactive material or internal combustion engines. Ooh! Or we could all get neat little hand cranks!
What am I going to do on my flight to Germany now?
Alan Cox is an important leader and resource in the Linux community. On behalf of all Linux users, I hope that, for the sake of our collective Cox, manufacturers can sort out these battery issues.
We regret to inform you, Mr. Cox, that since you were operating with an unsupported software configuration (i.e. Linux) we can not offer you support in regards to your issue (spontaneous incendiary explosion). Thank you for purchasing an IBM thinkpad.
If a battery is defective and may explode, how long would it take ?
For example, suppose you buy one replacement lithium battery nowadays; and you use it for X months; may you say "I have used it for X months, it did not explode, so it is not defective" ?
Or, otherwise, is it a defect that may show up in a random moment in the future?
Does anyone here at/. know?
Is his diary still in Welsh?
That's the silliest thing I ever knew. I used to read it, but now he's effectively cut it off for the non-Welsh speaking world.
Neither the MacBook or the iBook G4 have two latches on the screen, neither have audio jacks on the front, no apple notebook shipped with a 4 pin FireWire jack (on the front? are they serious??), etc.
Shouldn't all this exploding-laptop trend really lead to producing more durable cases for portable devices? Like, if a "laptop" really exploded like this while on someone's lap, the person could be seriously injured. If it [the laptop] had a harder casing, possibly made of titanium, the risk of injury would be much less.
I think that would depend on which part would be made more durable. If you reinforced the entire casing then you might just make the explosion build up more pressure and potentially making it even more dangerous. It would probably be a good thing to reinforce the entire casing except the back so the explosion is aimed in the safest direction, like a shaped charge.
IANALY, but you are on an interesting track. Products liability law in many jurisdictions in the US imposes liability if the plaintiff can show, among other things, that there was a reasonable alternative design. That is, a design that would have prevented the injury could have been built at the time that the original product was built and still been reasonable, so far as its utility and cost go.
So, if someone does get injured by an exploding laptop and can show that a harder case would have been a rea
Maybe somebody will build a laptop that doesn't require you to "take the battery out of the computer unless they need it." I have a UPS battery backup for my desktop system, and I don't have to pull the battery out of it when I'm not expecting to need to use the battery. That would defeat the whole point of having the thing. I think a lot of people are using their laptops like that, it's their main computer and they like the fact that it has a battery too so they can survive without it plugged in for an hou
They handle fire- and smoke-damaged equipment all the time.
At the risk of being arrested and taken to a home for the criminally obvious, don't breathe any of the smoke from an exploding battery. Some formulations burn into chemicals that you don't want anywhere near you, such as hydrofluoric acid [internatio...eryinc.com]. It's not that strong an acid but it's remarkably destructive to flesh. If you do get a whiff of smoke go to the emergency room even if you feel OK.
Yep. HF is straight up deadly. Eating away your flesh is the least of your worries when 3% covereage with.1M solution is enough to kill you in 48 hours. It's not a pleasant way to go, either.
I used to work with HF in my lab when I was a grad student. Let me tell you, you start to follow lab safety procedures REAL careful like.
thats what your teachers were talking about when they told you about plagiarism
For those that aren't aware, plagiarism is the practice of dishonestly claiming original authorship of material which one has not actually created, such as when a person incorporates material from someone else's work into his own work without attributing it. Within academia, plagiarism is seen as academic dishonesty, and is a serious and punishable academic offense.
Every 6 months or so, I take the computers outside and blow out the "Ghost Turds". I have a fairly dusty house, and when they are full of "Dust Bunnies", I know by the fact that my temp-controlled fans kick up speed at inappropriate times.
Pretty much all [london-fire.gov.uk] of [cheshirefire.gov.uk] the [fire-uk.org] UK [wiltshirefirebrigade.com]. And since it appears that the UK started forming fire brigades just after the Great Fire Of London [wikipedia.org], that's probably where the name originates.
