More than 37,000 battery packs for a laptop computer have been recalled in the United States and Canada after they were found to overheat and pose fire hazards.
Lenovo made the announcement this week that consumers should stop using particular ThinkPad notebook computers (see below) until they remove the battery pack and contact Lenovo for a free replacement.
The affected laptops were sold from October 2010 through April 2011, with roughly 34,500 of those being sold in the U.S. and 2,900 in Canada.
Lenovo said it has received two reports of the battery packs overheating, resulting in damage to the computer, battery pack and nearby property. No injuries have been reported.
Lenovo released the following information on which computers were affected:
This recall involves Lenovo battery packs sold with the following ThinkPad notebook computers: the Edge 11, 13 and 14 series, the T410, T420, T510 and W510 series, and the X100e, X120e, X200, X201 and X201s series. The battery packs were also sold separately. The black battery packs measure between 8 to 11 inches long, 1 to 3 inches wide and about 1 inch high. Recalled battery packs have one of the following part numbers starting with the fourth digit in a long series of numbers and letters printed on a white sticker below the bar code on the battery pack: 42T4695, 42T4711, 42T4798, 42T4804, 42T4812, 42T4822, 42T4828, 42T4834, 42T4840 and 42T4890.
Lenovo said users can keep using the ThinkPad notebook without the battery pack by plugging in the AC adapter and power cord.
