TOKYO: Japanese electronics maker Sony Corp said on Saturday it is investigating a fire incident on a Lenovo laptop that reportedly used a Sony-made battery.   

Media reports said a Lenovo Notebook computer equipped with a Sony battery caught fire at Los Angeles International Airport last weekend.   

The incident came after Dell Inc and Apple Computer Inc last month recalled almost six million Sony-made batteries, saying they could produce smoke and catch fire.  

A Sony spokesman said the Tokyo-based company is looking into the matter. He said, however, he is not aware of an official confirmation that a Sony battery was used in the laptop.   

Officials at Lenovo's Japanese unit were not available for comment.
