Product Information and Troubleshooting
The computer is unusually warm
It is normal for the computer to feel warm to the touch while it is in use. But if the computer
feels unusually warm, it may be overheating because a vent is blocked.
If you suspect that the computer is overheating, turn off the computer to allow the computer
to cool to room temperature. Then be sure to keep all vents free from obstructions while you
are using the computer.

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 computer 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).
✎
The fan in the computer starts up automatically to cool internal components and prevent
overheating. It is normal for the internal fan to cycle on and off during routine
operation.
