Hi, I have an Logitech cordless optical mouse M/N: M-RCQ142, P/N:810-000452. I am trying for the 1st time to connect it to my new laptop running windows 7 and when I push the connect button on the bottom of the mouse the blue light on top starts flashing but the computer is not detecting it (control panel, add new hardware). can you help me?

In the future you would help out if you gave a mode #

However, usually, aside from being dead, their are two good
things to try before despair:

1. You should disconnect the mouse and try blowing and perhaps wiping the area where the laser is as it may be that the laser is being blocked and therefore cannot function [be careful not to actually touch the laser itself and to not use materials that leave lint!] A cloth for glasses would be an ideal item, 2nd to compressed air.
   
2. You can try the all-out start again tactic: Remove the base unit (part plugged in) and remove the batteries. Now reboot your computer. Assuming you have Windows, after rebooting, plug the USB part of the mouse back into the computer, and reload good batteries. If you have not received a message from Windows yet, look for an 'association button', which is what you press either on the base, the mouse, or both at the same time. With many models (you didn't specify) you have to go through this 'Holding Down of The Button(s) so that the mouse and the wireless base will recognize each other

So, to review basically, you want to try and clear away and particles or build up from the view of the laser (on the bottom of the mouse)
And/or you will unplug the USB base and remove batteries, reboot (let Windows fully load) - replace the base and the batteries to the mouse, and finally if no recognition, look for a button somewhere on both the base and the mouse and hold it down for a good few seconds.

If you still have no joy, please post back here with model and a more specific detail of how it stopped working.

*Last Gem of Knowledge*
It has been known to happen many times, that if you contact Logitech and explain that your mouse stopped working by no fault of your own, Logitech will replace the mouse for free

Good Luck

Hello dcipher,

This is due to a missing Windows file called input.inf. The solution is as follows:
In Windows XP, you can use the MSCONFIG utility as described in the following steps:

1. Click Start->Run.
2. Type msconfig in the Open field, and then click OK.
3. Click the Expand File button.
4. Type input.inf in the File to restore box.
5. Type the path of the Windows XP .cab file where you want to restore the file from in the Restore from box. If you don't know the patch, click the Browse From button to locate the Windows XP .cab file.
   Note: The Windows XP .cab files are stored in the I386 folder on the Windows XP CD.
6. Type C:\windows\inf\ in the Save file in box. This assumes that Windows XP was installed to the default directory. If Windows was not installed to the default directory, you will need to adjust the path to point to the correct directory.
7. Click the Expand button.
8. Click OK. If you are prompted to restart the computer, click Restart.
   

After extracting the file and restarting, try installing the mouse software again. You should no longer see this error message.

Should you have any further questions, please feel free to post them here.

Should be similiar to this picture: Cordless Mouse Open

The back half of the top of the mouse should slide toward you.

you are probably better off buying a new one
unless you are lucky enough to find a used one

I would start by pressing the Connect button on the bottom of the mouse, then the Connect button on the bottom of the mouse receiver connected to your computer.

If that doesn't work, try replacing the batteries, then going through the Connect method mentioned above.

Testimonial: "Helpful. I did try the connect buttons. How do I replace the batteries?"
