3M Model Number LX451 Keypad Mouse

I purchased this mouse and it has always worked fabulous for me. I just got a new computer and cant seem to find my installation disk. I looked everywhere on the web and can't find a place to download the driver. Does anyone know where I can order a new cd?

    mouse works for a few seconds and then stops, after using the touch pad the mouse works for a few more seconds. This just keeps going thru this on/off sequence.

SOURCE: Hi there, I have a

check if the Num Lock is on. This should be the top left button on the keypad. It's a minor thing that's easily forgotten and easily overlooked. If there werent any instalation CDs with your keypad and mouse, there should be no aditional settings. These things are plug and play.

The keypad and keypad mouse don't always work

try to do a reinstall on your system .
if its stil not working try to open the laptop and check if there are dusts.
if still not working .
you can purchase an external keyboard and mouse. ^_^

Mouse: Must click 3 or 4 times to "pick" stuff. Highlighting "lets go"

Try compressed air to clean under the button. Alternativly try tapping the sides of the mouse gently on the desk - this could dislodge anything under the button

I don't think its a driver issue but you may as well try it. look for the mouse driver on the 3M web site
