Maximum PC: Sony is warning owners of Vaio Fit 11A laptops that the non-removable battery packs provided by a third party supplier could potentially present a burn hazard. In certain model Vaio Fit 11A notebooks released in February 2014, the built-in battery could malfunction and overheat, resulting in partial burns to the chassis and the PC. Since it's a non-removable battery, your only option is to stop using the PC and disconnect it from the AC adapter.
