A:AnswerIt's the same USB receiver for both the mouse and keyboard. However, you can definitely use a different mouse. You would just need to plug in that mouse's own USB receiver to separately connect it. This mouse has an on/off switch on the bottom, so you can turn it off to prevent two mice from connecting to your computer. You wouldn't be able to use this mouse with another computer though since it doesn't have its own USB receiver.
A:AnswerHello. It sounds like your keyboard needs new batteries. It takes 2x AAA batteries and you can change them by sliding up the top plastic piece.

A:AnswerDo I need a unifying receiver if I'm just replacing the current mouse with a replacement? The mouse that it came with is malfunctioning, so I want to order a new one - will it work with the current receiver? I do not want to occupy the last USB slot nor do I want a portable USB port.
A:AnswerHello Chelis, unfortunately the MK470 is not compatible with our Unifying Receiver. I apologize for the inconvenience, but looks like you'll have to get a new MK470 combo. Hope you have a great day.
