Lenovo has been forced into a second major laptop battery recall in six months.
The company is calling back 205,000 notebook batteries worldwide, after complaints from four customers that their batteries overheated after they had dropped or hit the laptops.
The defect caused minor eye irritation for one user, and damaged the property and computers of the others, according to the U.S. Consumer Product Safety Commission.
The recall affects the nine-cell, extended-life version of a battery pack manufactured by Sanyo Electric.
Lenovo sold the packs between November 2005 and February 2007 as an option in certain versions of ThinkPad notebook PCs in the R series, T series and Z series model lines, the commission said. The faulty packs have the part number FRU P/N 92P1131.
Buyers of those PCs had the choice to purchase either a standard six-cell lithium ion battery pack or longer-endurance nine-cell packs, said Lenovo.
The problem occurred with the pack, a box designed in tandem by Lenovo and Sanyo that holds the battery cells.
That is a different fault than that which caused Lenovo to recall more than 500,000 laptop batteries at the end of September 2006. Lenovo was joined in its recall by the other main laptop manufacturers who used battery cells made by Sony that were contaminated with metal shards that caused them to overheat or catch fire.
