Dear Lenovo Customer,

Lenovo and IBM Corporation in cooperation with the U.S. Consumer Product Safety Commission are voluntarily recalling certain IBM-branded lithium-ion batteries manufactured by Sony Corporation. These Sony batteries may overheat in rare circumstances. Lenovo will offer customers free-of-charge replacement batteries for all recalled batteries. View Battery recall FAQs.

IBM and Lenovo sold these Sony batteries in systems listed below between February 2005 and September 2006. Customers who bought one of the following systems may have a battery subject to this recall:

• ThinkPad R Series (R51e, R52, R60, R60e)
• ThinkPad T Series (T43, T43p, T60)
• ThinkPad X Series (X60, X60s)

Additionally, since these batteries can also be used with ThinkPad T4x Series or ThinkPad R5x Series systems, customers who ordered an extra battery or received a replacement battery for any ThinkPad T4x or ThinkPad R5x Series notebook PC between February 2005 and September 2006 may also have a battery subject to recall.

If your battery has been recalled, to continue using your ThinkPad notebook PC safely:

1. Turn off the system
2. Remove the battery
3. Power your system using an AC adapter
