Although Lenovo stated that their laptops were not vulnerable to spontaneous combustion such as Dell and Apple notebooks were, it seems that an incident at LAX airport where a Lenovo notebook PC caught fire has changed their minds. The notebook, a ThinkPad T43, was found to be equipped with a Sony battery which combusted after overheating causing a scene at the airport. In response to the event, Lenovo has told Reuters that they have launched a probe into Sony and are currently investigating the cause of the batteries’ explosion. Sony’s response to the airport incident was saying that they still had "not determined that the laptop in question was loaded with a Sony battery."
