Overheat Event
If an electrical smell from a portable electronic device (PED) is detected, or a PED is suspected of overheating, the passenger should be asked to turn off the device immediately. If the PED is plugged into the aircraft power supply the power supply should be disconnected if safe to do so and the in-seat power should also be turned off. Although a PED may be “off”, unstable batteries can still ignite and so the PED must remain off and monitored closely for the remainder of the flight.
