Months after joining other PC vendors in a massive recall of faulty notebook batteries, Lenovo has found a different problem with some models, and will recall 205,000 notebook batteries worldwide, the company said Thursday.
Lenovo made the move after four customers complained their batteries overheated after they had dropped or hit the notebooks. The defect caused minor eye irritation for one user, and damaged the property and computers of the others, according to the US Consumer Product Safety Commission.
The recall affects the nine-cell, extended-life version of a battery pack manufactured by Sanyo. 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 four-cell battery pack or longer-endurance six-cell or nine-cell packs, said Lenovo spokesman Ray Gorman.
The problem occurred with the pack, a box designed in tandem by Lenovo and Sanyo that holds the battery cells. It is a different fault than the metal shards that contaminated battery cells made by Sony, causing some batteries to overheat or catch fire and leading to the recall in 2006 of millions of notebook batteries used by nearly every PC vendor.
