Troubleshooting

Is an External Device Not Working?

If an external device does not function as expected:

Turn on the device as instructed in the device documentation. Some devices, such as external monitors, printers, and devices connected to the parallel connector, must be turned on before the notebook is turned on.

Verify that:

All device connections are secure.

The device is receiving electrical power.

The correct device drivers are installed.

Install the latest available system ROM. For instructions, see the Software Guide, Chapter 3, “Software Updates and Restorations,” on the Documentation Library CD.
