HP Notebook Computer and Mobile Workstation Battery Safety Recall and Replacement Program
In January 2018, in cooperation with various government regulatory agencies, HP announced a worldwide voluntary safety recall and replacement program for certain notebook computer and mobile workstation batteries. These batteries have the potential to overheat, posing a fire and burn hazard to customers. For this reason, it is extremely important to check whether your battery is affected.
Many of these batteries are internal to the system, which means they are not customer replaceable. HP is providing battery replacement services by an authorized technician at no cost. HP is also providing a BIOS update that places the battery in "Battery Safety Mode" so that the notebook or workstation can be safely used without the battery by connecting to an HP power adaptor. Batteries affected by this recall should immediately be put into "Battery Safety Mode".
