Cordless Desktop EX 90 Mouse Not Working

I just purchased a brand new Cordless Desktop EX 90. The keyboard works fine. However the mouse has a problem.

The mouse buttons get clicked but the mouse pointer does not move. What could be the problem and how to fix it.

I have reconfigured many times, changed the batteries and used mouse pad but it still does not work.

Pls help!!

    There are 3 parts: keyboard, mouse and USB RF Receiver. Yes,the USB receiver is connected, since the keyboard works without any problem and the mouse buttons work but the pointer doesnt move. BTW its a Logitech Cordless Desktop EX90

Got myself an ex90 so far no problems with keyboard or mouse,
How far away is your reciver from your mouse? try moving the reciver around.
Do you have anyother mouse software installed on your computer ?? if so uninstall old mouse softwear, reboot then try your ex90 mouse again.
If that fails I sugest you take it all back and get your money back or exchange for new hard ware under warranty.....

I took out the batteries from the Logitech cordless mouse last night, and when I put them in this morning, the mouse does not respond.  Pushing the connect button on the receiver does not seem to help.  Ideas please?

Can i connect my wireless logitech keyboard with out the mouse

Yes sir I have had one of those Logitech before and what you have to do it's not magic it's a signal that it gets to let him let him know that it's working properly and you probably need to reboot the signal and then it will probably work properly

My ex100 logitech mouse isn't working properly

Hi there

Your mouse buttons are stuck and can no longer hold firmly.

The best solution is to get a new mouse because repairing the mouse might cost almost the same price as buying a new one.

have a great day!

Remove the software. Reboot. Reinstall software "drivers" Then plug the receiver in. Push the connect button on the receiver, then the keyboard, then the mouse in that order. Hopefully that helps.

My mouse i working but i can't pairer my keyboard after conneting my mouse

Make sure the batteries in the keyboard are new and working. And also when you go to connect the keyboard, hit the connect button on the reciever first and then the connect button on the keyboard right after. If this still doesn't work it is a problem with the keyboard and you should contact the manufacturer or take it back to where you purchased it and get a new one.

The mouse and keyborard have to be in direct view of the reciever. Even a small obstruction will effect the operation
