Wow, so apparently TFS == TFA (which in turn is nothing but a copypasta of an AP release [google.com] from earlier today. Is there really no more information on this? For example, how hot is too hot? My laptop gets pretty freaking hot sometimes and I'd guess a fair bit of that heat finds its way into the battery.
- Heated cells vent flammable electrolyte gas - Cells begin venting at approx 470-500 Deg F - The electrolyte gas occasionally exploded due to hot surface ignition - Cells produce a pressure pulse when venting - As little as four cells can raise the pressure in a sealed 10m cubed chamber by one psi.
Kind of interesting. It looks like I probably don't need to worry
Several months ago, on a flight from Virginia to California, a zip-lock bag containing spare batteries for my phone and camera and several power&usb cables "disappeared" from my luggage. At first I thought I had left it behind, but that turned out not to be the case. A couple of months later, I had a nearly identical zip-lock bag in my carry-on (sans the camera battery, which I have not yet replaced). I was pulled aside for "extra scrutiny" specifically because of this bag. The TSA agent removed it
In reality, a checked laptop has never actually made it as far as the cargo hold.
Witty on topic text here. [xkcd.com]

Doing some quick looking, I came across a study which exposed lithium batteries to fire and heat [faa.gov] (PDF). On page 32-34 it says (paraphrased):
- Heated cells vent flammable electrolyte gas
- Cells begin venting at approx 470-500 Deg F
- The electrolyte gas occasionally exploded
due to hot surface ignition
- Cells produce a pressure pulse when venting
- As little as four cells can raise the pressure in a
sealed 10m cubed chamber by one psi.

Metal Lithium batteries!=Lithium-Ion batteries used in laptops. Metal Lithium batteries are too dangerous to be used in laptops.
