Both HP and Fujitsu are recalling the lithium-ion batteries used in some of their mobile devices. The batteries are overheating, causing a fire hazard.

HP Recall

HP is voluntarily recalling the lithium-ion batteries used in some of its HP notebooks and mobile workstations. Problems with the batteries came to light after eight people reported battery packs overheating, melting, or charring, according to the US Consumer Product Safety Commission.

The recall affects around 50,000 devices purchased in the United States and 2,600 machines bought in Canada. They were sold online and in brick-and-mortar retail stores from December 2015 through December 2017. The affected lithium-ion batteries were also sold as accessories and provided as replacements through HP and authorized service providers.

The recall affects certain models in the following notebook lines: HP ProBook, HP x360, HP Pavilion, HP Envy, and HP 11 Notebook. It also affects a few models in the HP ZBook line of mobile workstations. You can find a list of the affected models on the HP Notebook Computer and Mobile Workstation Battery Safety Recall and Replacement Program web page.

Not all the batteries in the affected models are part of this recall. If your device is one of the models listed on the recall web page, you need to run a utility to determine whether its battery is defective. You can download the utility directly from the recall web page.

If your device’s battery is part of the recall, HP recommends that you run an update that puts your device into what it calls the “Battery Safety Mode”. In other words, the update discharges the battery and disables future charging until the battery is replaced. You will still be able to use the device if you use an AC power adapter.

HP will provide you with a free replacement battery. It will also provide battery replacement services by an authorized technician at no cost. (Many of the affected models’ batteries are internal and therefore cannot be replaced by users.)

Fujitsu Recall

Fujitsu is voluntarily recalling the lithium-ion batteries used in some of its laptops. Under certain conditions, the batteries can ignite and cause a fire, according to the company.

Approximately 6,400 affected devices were sold online between July 2012 and December 2017. The batteries were also sold separately.

The recall affects several models of the Lifebook and Celsius line of laptops. You can find a complete list of the affected models on the Important Safety Recall – Fujitsu PC Voluntary Battery Recall and Replacement web page.

Like the HP batteries, not all the batteries in the affected Fujitsu models are defective. If you find your model listed on the recall web page, you can download and run a utility to see whether your device is using one of the recalled batteries. Alternatively, you can manually remove that battery and check its serial number. (The batteries in the Lifebook and Celsius laptops are not internal.) The recall web page includes instructions on how to do so.

If your laptop’s battery is part of the recall, Fujitsu will ship you a free replacement. Until you receive it, Fujitsu recommends that you remove the defective battery (turn off the system first) and use an AC power adapter to power the device.
