Safety Warning Notice
WARNING! To reduce the possibility of heat-related injuries or of overheating the computer, do not
place the computer directly on your lap or obstruct the air vents. Use the computer only on a hard, flat
surface. Do not allow another hard surface, such as an adjoining optional printer, or a soft surface,
such as pillows or rugs or clothing, to block airflow. Also, do not allow the AC adapter to contact the
skin or a soft surface, such as pillows or rugs or clothing, during operation. The computer and the AC
adapter comply with the user-accessible surface temperature limits defined by the International
Standard for Safety of Information Technology Equipment (IEC 60950).
