A battery in a Samsung Electronics Co Ltd notebook computer melted on Sunday, officials from the company and South Korea's fire department said.
The notebook battery emitted smoke after being used for about three and a half hours on a pillow, a fire department official in Seoul told Reuters by telephone.
The battery burned a bed and a floor a bit, but did not cause a big fire, he added.
A Samsung's spokesman said the notebook was the P10 model, which was produced in 2002 but did not give further details such as a producer of the battery.
