Depends if you are talking about the touchpad or a mouse you added. If it's the touchpad, you might have pressed the button to deactivate it. It is either near the touchpad itself or on one of the F? keys and you need to press a combination of the Fn key and the F? key with the touchpad icon. If it's a wireless mouse, check your batteries, check the on/off switch under the mouse. Try unplugging the receiver and plugging it into another usb port. Try somebody elses mouse also. If it really doesn't move at all, your laptop might be frozen, you can check this by pressing the windows key on your keyboard and if the start menu appears, it'S not frozen and you need to check your mouse or have your laptop serviced.
