IBM and Lenovo have recalled 526,000 Sony batteries for ThinkPad notebooks, becoming the latest notebook vendors to act on fire-prone power sources.

The companies advised owners of the batteries, which were sold worldwide with ThinkPads and as replacement units between February 2005 and September 2006, to return them to Lenovo for a free replacement. Lenovo took over IBM's PC division in May 2005.

The voluntary recall was announced in conjunction with the US Consumer Product Safety Commission after reports this month of a ThinkPad smoking and catching fire as a user was boarding an airliner at Los Angeles International Airport, the companies said in a statement. Apple, Dell and Toshiba have also recalled Sony notebook batteries this year.

The batteries recalled Thursday were sold worldwide with T Series (T43, T43p and T60), R Series (R51e, R52, R60 and R60e) and X Series (X60 and X60s) ThinkPads or as replacement batteries for those units.
