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.

ÅWARNING: To reduce the possibility of heat-related injuries or of overheating the computer, do not place the computer directly on your lap or obstruct the computer air vents. Use the computer only on a hard, flat surface. Do not allow another hard surface, such as an adjoining optional printer, or a soft surface, such as pillows or rugs or clothing, to block airflow. Also, do not allow the AC adapter to contact the skin or a soft surface, such as pillows or rugs or clothing, during operation. The computer and the AC adapter comply with the user-accessible surface temperature limits defined by the International Standard for Safety of Information Technology Equipment (IEC 60950).

The wireless network connection is not working

If a wireless network connection is not working as expected, follow these suggestions:

If you cannot connect to a corporate network, contact the network administrator.

Be sure that the wireless device is turned on and the wireless light on the computer is blue. If the light is off, press the wireless button to turn on the wireless device.

Be sure that the computer display is open and the antennae are free from obstructions.

Be sure that the cable or DSL modem and its power cord are properly connected and that the lights are on.

Be sure that the wireless router or access point is turned on and properly connected to its power adapter and the cable or DSL modem, and that the lights are on.

Disconnect and then reconnect all cables, and turn the power off and then back on.

Some external devices are not working

The PC Card slot or the USB ports may be disabled. Contact your network administrator for additional information.
