Just a heads up that there are a handful of potentially dangerous laptop batteries floating around out there. These ones are made by Sony but are found in certain models of HP, Toshiba, and Dell notebooks. The HP notebooks are the most at risk with about 32,000 affected batteries.
According to the U.S. Consumer Product Safety Commission, “There have been 19 reports of the batteries overheating, including 17 reports of flames/fire (10 resulting in minor property damage). Two consumers experienced minor burns.”
