Troubleshooting

■ Slide the power switch toward the front of the computer and

hold it for at least 5 seconds.

■ Disconnect the computer from external power and remove the

battery pack.

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 a printer, or a soft surface, such as a pillow, 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.

An external device is not working

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.

❏ The device is receiving electrical power.
