Engadget has the scoop on a Thinkpad that blew up at LAX. From the picture I’m virtually positive it’s a T4x/p (T40/p, T41/p, T42/p, T43/p). According to IBM/Lenovo Documentation (T40/p, T41/p, T42/p T43/p) they do ship some with Sony batteries, in addition to Panasonic and Sanyo. I personally have a Sayno in my T43. I believe the T60’s also have Sony in the mix (docs). I’m pretty sure that’s a 6 cell battery in there based on the contour of the rear of the battery (it’s burnt so it’s hard to be 100% positive with that picture quality.
So is it a Sony battery in there? Will there be a recall? My guess is this is going to be a very quick investigation. Considering how many business travelers have Thinkpads, and how many are using the T4x series right now, there are tons of these laptops on planes right now as I post this.
