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

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.

An external device is not working

Follow these suggestions if an external device does not

function as expected:

■ Turn on the device as instructed in the device user guide.

Some devices may not be powered by the computer, and

must be turned on before the computer is turned on.

Be sure that all device connections are secure.
