Q: Microsoft Wireless Optical Mouse 2.0A not working

I have a Microsoft Wireless Multimedia Keyboard 1.0A and a Wireless Optical Mouse 2.0A and have had them around 3 years or so. They were given to me with a computer but as the computer wasn't working I didn't have a chance to use them until about a year and a half ago. Up until now they have been working fine, almost without event. I currently have them plugged into a laptop and my girlfriend unplugged them the other day to plug into her laptop so she could play a game. After plugging them back into the original laptop only the keyboard will work.


I have pressed the sync button on the receiver and then on the mouse itself and it seems to work as the lights on the receiver go from flashing to solid, yet when I move the mouse it doesn't respond on the screen. I tried changing the batteries, moving all other devices away from the reciever, unlpugging it, resetting the computer, everything. I searched Microsoft Support but it seems my mouse is an outdated model and there is literally NO info on how to fix it. I tried the steps they suggested on other Wireless models but to no avail. What could the problem be?



Hi jaeger138,

Did you check the mouse on a different computer?

You may try the following methods and check if it helps:

Method 1: Test the device on a different computer

If the issue continues to occur, test the mouse on a different computer in a different environment. If you can replicate the problem in a different environment, you may have a defective device. If this is the case, see the "More Information" section for information about how to contact Microsoft Supplemental Parts to obtain a replacement device.

If the device works without any issue on a different computer, go to method 4.

Method 2: Test the mouse by using the Mousinfo diagnostic tool

The Mousinfo diagnostic tool is installed together with the IntelliPoint software. If you do not have this software, you cannot open the tool.

To install the IntelliPoint software, visit the following Microsoft Web site: (

Note This tool may not work with Bluetooth devices.

To open the Mousinfo tool, follow these steps.

Windows Vista or Windows 7

1. Click Start, Select All Programs and click Accessories.

2. Click Run.

3. In the Open box, type mousinfo, and then click OK.

Method 3: Try another USB port for the wireless receiver.

If using a USB hub, try connecting the receiver to a port directly on the computer. The problem may be a bad port or hub. Restart your computer after reconnecting the mouse's wireless receiver.
