Cause: A number of wireless mice and keyboards are available, all of which work with your computer’s infrared port. These devices are great because they allow you flexibility and a computing experience without aggravating wires. However, you can have some problems with infrared devices.
There are some common reasons and solutions for infrared problems:
• Distance/obstruction: In order for infrared devices to work--> the mouse or keyboard must be within range of the infrared port--> and other objects must not be blocking the infrared beams.
• Unconfigured infrared port: If the devices do not work at all--> you may need to configure your infrared port--> You’ll need to check both your computer’s documentation and your keyboard or mouse documentation for configuration assistance.
