The Computer Is Unusually Warm - HP nc8430 - Notebook PC Getting Started Manual

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