Japanese electronics maker Sony (6758.T) said on Saturday it is investigating a fire incident on a Lenovo (0992.HK) laptop PC 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 (Nasdaq:DELL - news) and Apple Computer (Nasdaq:AAPL - news) last month recalled almost 6 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, without specifying. He also said, however, he is not aware of an official confirmation that a Sony battery was used at the PC.

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