How do I connect my Dell bluetooth mouse up to my PC?

My sister had a bluetooth mouse come with her laptop and she doesn't use it ever. Our PC is a Dell as well and has bluetooth enabled. How can I set up a connection between the mouse and the PC so that I can start using it instead of my wired mouse. Thanks.How do I connect my Dell bluetooth mouse up to my PC?first, make sure your computer has bluetooth capibilities. if it dosent, buy a bluetooth adapter. once you've amde sure your computer has bluetooth, install the mouse driver (there should be a disk with the mouse. install that). if your mouse is still not working, try going into the controll panel and messing around with your bluetooth options.
