Hewlett-Packard announced a voluntary recall of lithium-ion batteries used in a number of HP and Compaq notebook computers.
The recall, which was done in cooperation with the U.S. Consumer Product Safety Commission, affects a reported 54,000 units.
Consumers should stop using recalled products immediately unless otherwise instructed, according to the announcement, because the batteries can overheat and pose a fire or burn hazard.
The affected computers were sold from August 2007 through July 2008, HP said, and affected battery packs were also sold separately.
The list of affected models can be found here.
HP said: "Consumers should immediately remove the batteries referenced above from their notebook computer and contact HP to determine if their battery is included in this recall (even if the battery was previously checked). Consumers with recalled batteries will receive a free replacement battery. After removing the recalled battery from their notebook computer, consumers may use the AC adapter to power the computer until a replacement battery arrives. HP recommends that only batteries obtained from HP or an HP authorized reseller be used with HP notebook PCs."
