According to Consumer Reports, HP has received eight reports of batteries overheating, melting, or charring. Models affected are: all ProBook 640, 645, 650, and 655 models in the G2 and G3 series, the HP ZBook 17 G3 and G4, the HP ZBook Studio G3, the HP x360 310 G2, the HP Pavilion x360, the HP Envy M6, and the HP 11. However, since the batteries in these laptops are not meant to be replaced by consumers, HP will send an authorized technician to replace the battery properly.
Many of these batteries can not be replaced by customers. Three reports have included property damage "totaling $4,500", says HP, and on report included a first-degree burn.
For customers with further questions, HP has set up a detailed FAQ on the battery recall. Not all batteries of the affected laptops are part of the recall, which is why the company has released a HP Battery Validation Utility to check if the particular battery in a notebook computer is affected.

During the process, there will be an option provided where the user is asked to choose if they'd like to enable what the company is referring to as the "Battery Safety Mode". Instead, they should only be done via authorized service outlets where the batteries would be replaced free of cost.
"HP's primary concern is for the safety of our customers", it said. While in "Battery Safety Mode", the laptops can still function safely while connected to an HP power adaptor.
Why this matters: Battery recalls happen every so often, often due to manufacturing issue.
