What safety precautions should I follow to prevent overheating the HP EliteBook 9470m?

Do not place the device directly on your lap or obstruct the device air vents, and use it only on a hard, flat surface. Do not allow soft surfaces such as pillows, rugs, or clothing to block airflow, and do not allow the AC adapter to contact the skin or soft surfaces during operation. The device and AC adapter comply with the user-accessible surface temperature limits defined by IEC 60950. (Page 3)
