This time a year ago HP recalled 100,000 computers due to overheating batteries, which expanded a previous recall of 41,000 units over the same issues.
If you want to check whether your HP laptop battery is affected, you can find out by visiting HP's website. The update puts the battery in "Battery Safety Mode", which forces the battery to discharge and cease charging again until the mode is disabled. They were also sold as accessories or provided as replacements through HP or an authorized HP Service Provider. HP is looking into suspected issues with a supplier as the source of the battery problems.
"We are taking immediate action to address this issue including a voluntary recall and replacement of the batteries", HP's statement says. "This action pertains to 0.1 per cent of the HP systems sold globally over the past two years".
HP of Palo Alto, Calif., is recalling about 52,600 lithium-ion batteries for HP notebook computers and mobile workstations sold in the U.S and Canada. Notebook users can download HP's Battery Validation Utility to check if their laptop's battery needs to be replaced.
Being as most of the affected batteries are internal and not user-replaceable, HP has made a decision to provide users with free battery replacements from its authorised technicians.
This follows eight reports of lithium-ion batteries overheating and/or melting, and in one case causing a first-degree burn to someone's hand, with three further cases citing resulting property damage (presumably caused by fire, of course) to the tune of $4,500.
There's also a BIOS update that puts the battery into "Battery Safe Mode" to prevent it from operating in a unsafe way.
Why this matters: Battery recalls happen every so often, often due to manufacturing issue. If it is, instructions are provided for operating the computer or workstation in Battery Safe Mode.
The affected devices include ProBook (64x G2 and G3 series, 65x G2 and G3 series), ZBook (17 G3, 17 G4, and "Studio" G3), x360 310 G2, Pavilion x360, Envy m6 models.
"During the reboot process, an option will be presented to enable Battery Safety Mode".
