The batteries can overheat and pose fire and burn hazards, according to a statement released Thursday by the United States Consumer Product and Safety Commission.
It seems the company has learned its lesson since the much-reported case in 2011 in which HP recalled 162,000 battery units.
And, as an additional safety measure, HP has instructed customers who determine that their battery should be replaced to use the BIOS update enabled by the company to set the battery to "battery safe mode", a mechanism created to discharge the defective battery and prevent continued use. The batteries were also sold as accessories or replacement batteries for the HP ZBook Studio G4 mobile workstation. HP is looking into suspected issues with a supplier as the source of the battery problems.
The company has received eight reports of battery packs overheating, melting, or charring, including three reports of property damage totaling $4,500 with one report of a minor injury involving a first degree burn to the hand.
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. The company is also providing a free battery replacement, but the batteries can not be replaced by customers themselves.More news: Microsoft halts some AMD chip Meltdown patches after PCs freeze
"Many of these batteries are internal to the system, which means they are not customer replaceable".
Not all of these products could be affected but HP highly recommends to check through a useful tool, the HP Battery Program Validation Utility. If the validation process identifies a battery as being eligible for replacement, the BIOS update should be applied and the system should be rebooted. This mode will discharge the battery and prevent it from being recharged until the battery is replaced.
Why this matters: Battery recalls happen every so often, often due to manufacturing issue.
"During the reboot process, an option will be presented to enable Battery Safety Mode". This would allow customers to safely use their notebook and mobile workstations while having an HP power adaptor connected.
Included in the recall are a number of HP ProBook G2 and G3 models, ZBook 17 and Zbook Studio laptops, and Pavilion x360 and Envy m6 laptops, among others.
