Airlines are banning the use of Dell and Apple laptops on their flights because of the fire risk their batteries pose.
The Associated Press has reported that South Korea's largest airline, Korean Air, has already banned Dell and Apple laptops. Other airlines are believed to be planning a similar move.
Last month, Dell recalled 4.1 million laptop batteries that were made on its behalf by Sony. After a similar fire hazard problem, Apple recalled 1.8 million batteries that were also made by Sony.
Recently, Panasonic recalled 6,000 batteries that were sold with its laptops in Japan, but those batteries were not manufactured by Sony.
The heightened terrorist threat in the UK recently led to laptop use being briefly banned on flights, before being allowed again.
But faulty batteries, rather than terrorists, may now prevent executives from opening a spreadsheet on a flight.
