Logitech ex 110 cordless combo will not connect to themouse or keyboard. all 3 lights on reciver stay on all time. when push connect no flash of these lights. have tried on 3 different computers (vista and 7) tried reinstall. updated touchpoint. no help

810-000755 is the part number for the Logitech C-bt44 USB receiver for the Logitech Cordless Desktop EX 100. See http://support.logitech.com/en_us/product/cordless-desktop-ex-100-product/faq#link_19321 . 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.

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

whenever you chage the battery you have to syncnonize your keyboard and mouse to sensor of the reciver. you can see on the back side of the keyboard there is connect button just press it and on the recevre side also press the connect buton same setting do with mouse also.

Your EX 110 receiver has 3 indicator lights (LEDs) that display the status of the Caps lock, Function key, and the Num lock during normal operating mode. These lights will also flash when the connect button on the receiver is pressed.
LED A: Indicates that the Caps Lock (Capital lock) key is on when lit.
LED F: Indicates that the F keys are in Standard F Keys Mode when lit and in Enhanced F Keys Mode when the LED is off.

• Your EX 110 keyboard has an Enhanced F Keys Mode for F keys that provides additional functions you can program. See Knowledge Base article 9526.

LED 1: Indicates when the Num Lock (Number lock) key is on. This function allows the number pad to produce only numbers

THEY NEED LINKING TOGETHER. YOU NEED TO REINSTALL THEM BOTH.

i WOULD RETURN IT. BUT MAKE SURE YOUR GARENTEE IS EXTENDED BECAUSE OF THE REPAIR NEEDED.

The button opens your default email program.
Here is a good tutorial on how to fix that:

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

have you checked that it is the USB port if it is not in the USB port it will not respond
