HP Notebook Computer and Mobile Workstation Battery Safety Recall and Replacement Program

Battery Safety Mode / Bios Update Information

HP released a BIOS update in August 2019 that includes batteries added by the program expansion. The updated BIOS 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".

Battery Safety Mode is only applicable to HP products affected by this recall. If the validation process identifies a battery as being eligible for replacement, the BIOS update should be applied and the system should be rebooted. During the reboot process, an option will be presented to enable Battery Safety Mode. Accepting Battery Safety Mode causes the battery to discharge and to cease future charging until Battery Safety Mode is disabled. HP strongly recommends accepting Battery Safety Mode so that the notebook or mobile workstation can be safely used by connecting to an HP power adaptor.
