Try downloading the driver in your computer again. The registry file can be corrupt from other downloads. It has happened to mine twice so far in two years The drivers can be found at this link below...Remember I do not know what model you have so a 3000 & a 4000 model link for each are showing for you below here

Install the proper driver for Keyboard optical receiver may solve your problem.

Just to clarify, this is a wireless optical mouse, right? Please try the steps below:

1. Use fresh batteries.
2. Make sure that the mouse is turned on.
3. Check if there's a connect button on the wireless receiver and underneath the mouse. If there is, try holding down the two connect buttons at the same time for five seconds and then release them both.
4. Try moving the mouse.
5. Make sure that there are no possible wireless interference between the wireless receiver and mouse like the base of a cordless phone, cell phone etc.

If same problem occur after doing the steps below, then you may want to contact the manufacturer for RMA. This Microsoft 4000 has a three year limited warranty.

Thank you!

Go to this link, its on microsofts homepage directed at the laser desktop 4000, from that point all you have to do it click on download software under downloads on the right side and then identify your product with the drop down menu's, a manual should be here.

Try reinstalling the driver of your optica mouse.
