The machines affected represent 0.1% of HP's computers sold globally between December 2015 and December 2017.
The recall involves lithium-ion batteries for HP Notebook computers and mobile workstations.
Affected models include HP ProBook, HP ZBook, HP x360, HP Envy m6, HP Pavilion x360 laptops and more.
Among the incident reports were three reports of property damage, totalling US$4,500, as well as one case where a customer suffered a first-degree burn to the hand. Numerous batteries, however, are internal to the notebooks and mobile workstations, meaning a technician's services will be necessary to replace them.
Nintendo Switch officially now the fastest-selling video game console ever
And in terms of recovery from the Wii U era, Nintendo's previous home console sold 7.3 million units over its first 10 months. If you still don't have a Switch , it might be time to admit that it probably does live up to the hype.
HP says they have received eight reports of battery packs overheating, melting, or charring. As these batteries are sealed inside the laptop, a qualified technician will be called upon to carry out the replacement. "We are taking immediate action to address this issue including a voluntary recall and replacement of the batteries".
If users that do have an affected battery however, HP has advised against removing it manually.
In addition, the company has pushed a BIOS update that puts affected batteries in "Battery Safety Mode", which allows the laptops to continue working without their batteries by connecting to an HP power adaptor. When enabled on an affected system, the battery will be discharged and then can't be charged (at least without disabling the safety mode).
Why this matters: Battery recalls happen every so often, often due to manufacturing issue. No one wants a repeat of the Galaxy Note 7 debacle.
