The affected batteries shipped with certain HP ProBook 64x (G2 and G3), HP ProBook 65x (G2 and G3), HP x360 310 G2, HP Envy m6, HP Pavilion x360, HP 11 notebooks, and HP ZBook (17 G3, 17 G4, and Studio G3) mobile workstations. Some of the affected batteries were also sold as replacements.
In many cases customers won't be able to replace the batteries themselves since the power cells are internal, so HP is covering the cost of installing a replacement via an authorized technician.
"HP 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," CSPC said in a statement.
HP ended 2017 as the world's largest PC vendor by shipments and the only vendor that actually increased shipments amid shrinking sales across the industry.
HP said it's providing BIOS update to put affected batteries in Battery Safety Mode, which discharges the battery and prevents it from charging until Battery Safety Mode is disabled. Users will still be able to use the device but only when connected to an HP power adapter.
