An Alaska Airlines Boeing 737-900, registration N285AK performing flight AS-29 from Newark,NJ to San Francisco,CA (USA), was enroute at FL360 about 40nm east of Columbus,OH (USA) when the battery of a passenger's laptop suffered a thermal runaway. Flight attendants extinguished the fire and secured the device while the flight crew diverted the aircraft to Columbus, requested emergency services on stand by for the arrival and landed the aircraft safely on runway 28L about 25 minutes later.
A passenger reported the aircraft made an unscheduled stop at Columbus due to thermal runaway of a laptop on board.
The aircraft remained on the ground for about 2.5 hours and reached San Francisco with a delay of 3 hours.
