The wireless mouse works but the laser 5000

To make them both work together you need IntelliPoint for the mouse and IntelliType for the keyboard and system no newer than Windows 7. For explaining incompatibility issues see:

Not really a code, just first press button on top of your receiver and then the button on the bottom of the mouse. The receiver LED should stay green when they are connected. If this does not happen check that you are using IntelliPoint Mouse Software. See more:

The software might not be compatible. but for you to use the wireless keyboard and mouse you don't need a software just plug the wireless adapter and sync the keyboard and mouse . it will start working

Replace the batteries, look under the mouse you should see a removable cover, the batteries should be in there.

Normal 0 Press the Receiver button (and the lights will start flashing.
Then if the Keyboard isn't working, press the small RESET/CONNECT button on the back of the board to connect the keyboard to the receiver.

If the MOUSE isn’t working, push the small RESET/CONNECT button on the back of the mouse to connect to the receiver. Then they should work okay.
Hope this helps. Bud

Make sure the batteries are good and then follow these instructions.

have you turned the keyboard upside down and pressed the connect button?

I suppose there is a reset button on the keyboard or the software provided so I suppose it could be possible, I don't know.
I use a Microsoft Wired Keyboard...
But Best of luck.

Hi there.
There should be a button underneath the mouse and on the reciever that says "connect" press them and the mouse should now work.

Good luck and thanks for using Fixya!!!

Make sure that the batteries are good and try pressing the receiver button and then on the bottom of the keyboard press the small button that re-sets and connects the keyboard to the receiver. It then should work properly. Hope this helps. Bud
