Normal 0 Turn the mouse over and find the small rest/connect button on the bottom of the mouse and press it to Reset/Connect the mouse to the receiver and work properly.
If not, try pressing the receiver button and then press the mouse. This should be done whenever you change batteries or glitch.
Hope this helps you. Bud

What is logitech 810-000755 used for or what does it do

810-000755 is the part number for the Logitech C-bt44 USB receiver for the Logitech Cordless Desktop EX 100. See . This is the section of the FAQ on using the EX 100 with other USB receivers. The receiver lets select Logitech wireless keyboards and mice communicate with the computer that has this device plugged in. The 810-000755 also works with the Logitech cordless desktop (keyboard/mice) EX 110, and the MK 300. There may be other keyboards and mice that communicate with this receiver. However, newer Logitech keyboards and desktops (keyboard/mice) may not use this receiver.

I hope this helps. Note: the EX 100 uses 2 alkaline AA batteries in the keyboard and 2 alkaline AA batteries in the mouse to communicate with the receiver. I believe the other keyboards and desktops that can communicate with the 810-000755 also use alkaline batteries which last ~6 months before they must be replaced.

Unhooked everything to move computer. When reconnected cannot get mouse to work. have reset it and it still won't work. cannot get into computer without the mouse! Thanks!

Even when they do not normally need it you can try the logitech connection utility.

this shoudl also be installed on your system if you installed setpoint. In the program files folder there is logitech inside that there shoudl be 2 setpoint folders. A and B. Look in B and the connectin utility should be in there.

Connect an additional wired keyboard to your pc. And when the freeze happens check if the pc responds at all, using the wired keyboard. If its not responding , its an indication of a faulty PSU or motherboard.

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.
