The recall was announced by the U.S. Consumer Product Safety Commission and expands an earlier recall of 70,000 of the same type of batteries.
The earlier recall came after two reports of the batteries overheating. The commission said that since then, HP has received 38 additional reports of the batteries overheating, causing 11 minor injuries.
HP says the computers at issue were sold in stores and online from August 2007 through July 2008. The battery packs were also sold separately.
