If you own the Fujitsu P1510d Tablet PC, you should head over to the Fujitsu battery pack replacement program site. Fujitsu will be updating that page with more information after consulting with Sony on how customers can get replacement batteries.
Here are the models affected sold outside of Japan:
LIFEBOOK P1510, P1510D, P7120, P7120D
LIFEBOOK S7020, S7020D, S7025, S7025D
LIFEBOOK C1320, C1320D
