Is The Computer Unusually Warm - HP Compaq NC6320 Getting Started Manual

Troubleshooting

Is the computer 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, allow the
computer to cool to room temperature. Then be sure to keep all
vents free from obstructions while you are using the computer.
Ä
CAUTION: To prevent overheating, do not obstruct vents. Use the
computer only on a hard, flat surface. Do not allow another hard
surface, such as such as a printer, or a soft surface, such as a pillow
or a thick rug or clothing, to block airflow.
✎
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.
