To verify infrared support on a computer
Verify that your computer has an infrared transceiver (the transceiver will appear as a small, dark red window).
If your computer does not have an infrared transceiver, see your manufacturer's documentation to verify whether IrDA functionality is supported.
Open Device Manager
Double-click Infrared Devices.
If you have an infrared transceiver, but Infrared Devices does not appear in Device Manager, you do not have an infrared device installed.
If no infrared devices are listed, do one or both of the following:
Enter BIOS setup to verify whether the infrared device is enabled in BIOS, in IrDA, or Fast IrDA (FIR) mode. For information about how to enter BIOS setup, see your computer manufacturer's documentation. If the infrared device is disabled in BIOS, you might be able to use your computer's BIOS setup to enable it.
See your computer manufacturer's documentation to determine whether the BIOS needs to be updated.
Verify that at least one infrared device is listed and that it is enabled.
If infrared devices are listed but they are not enabled, verify that the infrared devices are installed correctly on your computer. For more information see Related Topics.
To open Device Manager, click Start, and then click Control Panel. Click Performance and Maintenance, and then click System. On the Hardware tab, click Device Manager.
Infrared transceivers are now installed in nearly all new portable computers. If your computer does not have an infrared transceiver, but it supports IrDA, and IrDA is enabled in BIOS, you can install an external infrared transceiver.
