Affordable Laptop Service advises Safety First for the most urgent laptop catastrophe...FIRE!

Of course you want to save your laptop, but how you deal with a laptop fire can be a life and death matter. It would seem logical to disconnect the ac power source from the wall. However, this won't put out the fire. In fact, a battery that has escalated to the point of spontaneous combustion will continue to burn even if ejected from the laptop. On this page is presented some of the best pertinent information available online from a variety of sources.

Don't try this at home, kids.

    Based on my experience as a volunteer firefighter, I'd like to share some info that doesn't cost and arm or a leg...but may save both in the case your laptop/battery explodes:
  • Firstly, DON'T USE WATER.
  • It's best to use a dry chemical extinguisher (type "C") on an electrical fire.
  • However, use a dry powder type "D" extinguisher for the dense chemical battery (NiMH, Lith-Ion, plain old alkaline, etc.). The type "D" extinguishers are designed for chemical and combustible metal fires (e.g. magnesium fires with some automobile engines). You should be able to use the "D" type extinguisher to put out electrical fires as well.
  • It may seem like an odd idea, but dumping sand on a chemical fire also will work to an extent. This is just a simple smoothering technique.

The following few paragraphs remain posted as "Being Smart with Laptop Batteries"

...We have been dealing with the largest recall in history that the laptop segment has ever had. This one is particularly important because the result of a battery failure, which could come at an increasing rate, is a very hot fire that is potentially life threatening and incredibly difficult to put out. This points out the danger of any technology that stores energy. Even a Cell phone, were it to short out, could create a fire or cause a burn suggesting that if the battery on one is damaged it should be replaced immediately.

But laptops have large batteries and their danger is simply greater which is why both Dell and Apple did the right thing and issued a recall placing the safety of their customers ahead of their own need to control cost and protect the brand. Sadly, in this case, it wasn't their fault but it was their problem to address it and fortunately Sony is covering their costs. However there remain a couple of things that concern us.

When we started down this path Sony was adamant that only Dell was impacted because the batteries came off a manufacturing line that had been dedicated to Dell. Then Apple announced their recall and it was clear, and we'll be kind here, that Sony was "mistaken". Our understanding is that the root cause of this problem is a combination of a manufacturing process shared across multiple Sony lines.

Rough estimates suggest that something like 2M additional batteries attached to laptops from other vendors will remain active in the market after the Dell and Apple recalls finish. At this time (August 30th, 2006) we can't be sure who the remaining vendor is but this information does suggest that it would be prudent to be careful regardless of who made your laptop computer.

Laptop Battery Safety Recommendations

  • One thing to keep in mind is that the Sony practice that resulted in the contamination was apparently widely done a few years back by virtually everyone in the industry. Sony was simply slow to do the required line upgrades which are partially why the problem is hitting them first. Newer batteries have better protection and, while nothing is certain, replacing your older battery is probably wise regardless of who built your laptop computer.
  • Lithium Ion batteries, under normal laptop use, have a service life of about 18 months anyway and if you have one that is older, it is probably time to replace it. A newer battery will not only be safer, but it should give you battery life that is a substantial improvement over what you are now seeing.
  • It is safer to store any high capacity battery discharged rather than charged, if it does short out for any reason, the lack of power makes the short a non-event and it will simply fail when you try to charge it rather than creating a fire.
  • It is not only safer to run a laptop on AC with the battery removed it will add to the life of that battery significantly. We've seen reports indicating that most rechargeable batteries, including Lithium Ion, can almost last indefinitely if they aren't constantly charged. Treated properly, your new Lithium Ion battery could outlast your laptop if you simply remove it and set it aside while your laptop is plugged in. If you do this with a charged battery put it someplace where it isn't near flammable materials and you should be relatively safe and your notebook will be vastly better protected.


However this all turns out, be prudent and be safe, you should be afraid of your batteries but you should, much like you do with other hazardous materials, treat them appropriately and if yours is under recall make sure to replace it as quickly as possible. To check for battery recall, take the link from the Laptop Resource column on the Home page to the support page of your laptop's manufacturer.
