Troubleshooting the Infrared Port
This section provides a procedure for troubleshooting the computer’s infrared (IR) port.
Make a copy of the Diagnostics Checklist found in Chapter 5, “Getting Help,” and fill it out as you perform the following steps:
1.Check the setting for the Infrared Port option in the System Devices menu of the Setup program.
For information on the Setup program, see Chapter 2, “Customizing System Features.” Is the Infrared Port option set correctly for the external device with which you are communicating?
Yes. Go to step 3.
No. Go to step 2.
2.Change the Infrared Port option to the appropriate setting, and then reboot the computer.
Is the problem resolved?
Yes. The problem is resolved.
No. Go to step 3.
3.Insert your diagnostics diskette into drive A, reboot the computer, and run the Serial Ports device group in the Dell Diagnostics. (See “Running the Dell Diagnostics” found later in this chapter.) The Serial/Infrared Ports device group checks the basic functions of the computer’s infrared logic.
4.Do the tests complete successfully?
Yes. The infrared port is functioning properly. There may be a problem with the infrared application program or with the external device. Check the documentation that came with the application program and with the external device.
No. Call Dell for technical assistance. (See Chapter 5, “Getting Help,” for instructions.)
