A battery in a Samsung laptop melted on Sunday in South Korea. The battery emitted smoke after being used for about three and a half hours on a pillow. The battery burned a bed and a floor a bit, but did not cause a big fire. A Samsung's spokesman said the notebook was the P10 model, which was produced in 2002 but did not give details such as a producer of the battery. "We are checking details of the incident," the company spokesman said. Last month, a battery pack in a LG notebook computer exploded while in the sleeping mode.
