Lenovo is a computer manufacturer that is a subsidiary of HP. If you want to program specific keys (known as "multimedia keys") on your Lenovo laptop or desktop computer keyboard, you will need to use a dedicated utility in your Control Panel. This icon will be pre-installed on all Lenovo computers, but note that it is exclusive to this brand and you will not be able to follow these directions to program other types of computer keyboards.
Click on "Start" and select the "Control Panel."
