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.
