I was just checking out the Sony support website when I came across the following:
"Sony to Initiate Global Replacement Program for Notebook Computer Battery Packs"

Here is the link, this is for the canadian site but there is a spot to change to the US website:
I am not aware of any issues with Sony notebooks but given that Sony was the maker of all the problem batteries for Dell, IBM/Lenovo, Toshiba & Apple I would not be surprised to see Sony doing a recall on some of thier notebook batteries too.
