Laser no longer working

1) Try to download and install a free driver updater software, e.g. http://www.innovative-sol.com/drivermax/index.htm - let it scan and update all your missing drivers - it may fix USB general problems if this causes also the mouse problems.
2) If it doesn't help - then there might be problem with the laser beam of your mouse (check the laser beam while the mouse is still moving, and then compare it with the beam when the mouse has stopped moving, maybe the laser beam is out). In this situation - bring it to the warranty repair service or ask for replacement from your seller.

i bought a new mouse

I have a miscrosoft wireless laser mouse 6000, and it also stopped working on my laptop. I changed the battery, still not working. I tested the battery in another device, and it was good. I moved the mouse to another computer, and it did not work. The light on the usb connector was lit. [No changes at all to my laptop.]. It seemed like there was no power to the mouse, and I looked at the contacts inside the mouse. The contact just inside the battery opening appeared to be bent down away from the contact on the battery tray. So, I pulled it up a little so it would connect when the battery drawer closed, and (after tweaking it a couple of times), it finally worked!

Have you tried to resync the mouse with the receiver. Usually,you need to press the button on the reciever first, then quickly hit the button on bottom of the mouse.

Remove the battery of the mouse and install new one and then press connect button from the mouse side and the receiver side also.

THE POWER SOURCE IS GETTING LOW AND IT IS TIME TO CHANGE THE BATTERIES

This may not be a solution for you but at least it may explain the cause of the problem. I recently had the same problem - the scroll wheel suddenly began to go crazy, jumping all the way to the bottom or the top of a document, or randomly skipping around. The unit was still under warranty, and Microsoft sent me a new mouse. Since they did not require me to return the old mouse, I decided to take it apart to see if I could find the problem. I found poorly soldered electrical joints to the optical sensor & LED which convert the scroll wheel movement to electrical signals. After I resoldered these connections the mouse worked fine again.

First try this
Normal 0 Turn the mouse over and find the small rest/connect button on the bottom of the mouse and press it. This should connect the mouse to the receiver and work properly. If not, try pressing the receiver button and then press the button on the mouse. This should be done whenever you change batteries or glitch.
If that doesn't do it theen try this.
Normal 0 Disconnecting the Mouse Receiver from the USB port and reinstall the CD software program. When the program asks you to connect the Mouse Receiver to the USB port, do so and it should work.
Hope this helps. Bud

I manage to find the solution to this elsewhere on this website,
