Logitech keyboard F Lock works but nothing else Connectivity?

I have a Logitech Cordless Mouse and Keyboard pair (s/n MCT40403612) I have brand new batteries and hte mouse is currently connected and working fine. The issue is hte keyboard, when I try ot connect the the light signify the connection is sucess full but the only keys that work are the F Lock that turns on and off a light on hte recieve (which leads me to believe it is talking to the reciever) and the user key which does successfully log me off of the computer (which leads me to believe the keyboard can communicate with the comupter)

the only thing is no other keys seem to repond, I know of nothing that I have spilled on the computer to damange the other keys. This is an old keyboad and mouse (4-5 years) any help would be greatly appreciated.

Reply to this issue from Logitech Tech Support:
Thank you for contacting Logitech Technical Support. My name is Susan and I will be assisting you with Incident # xxxxxx-xxxxxx .

I understand that the keys on your keyboard are not responding except the F lock key and the battery indicator key. Please correct me if I misunderstood you.

It appears that your keyboard might be encrypted during first installation.

To try and resolve this issue, I would like you to try and decrypt your keyboard. You can refer to the steps below on how to do this:

1. Press Ctrl + Alt +F12 key on the keyboard.
2. Press the Connect button on the receiver.
3. Press the Connect button underneath the keyboard.
4. Press the ESC key on the keyboard.

Once you have performed the steps above, test the keyboard in simple text applications such as Notepad or MS words to verify if the problem persists.

Additionally, you can try the following steps should the steps above was unable to resolve this incident:

a. Press the Connect button on the receiver for 10 seconds.
b. Wait for 20 seconds and then press the Connect button on the receiver again. Press the Connect button on the mouse.
c. Insert fresh new batteries back into the keyboard.
d. Press the Connect button on the receiver.
e. Press the Connect button on the keyboard.

This would help to isolate the cause of the incident that you are experiencing.

If this does not address your question, please update this incident, describing the results after following my suggestions. Or, if you prefer, you can contact us directly by the phone numbers listed below.

Thank you for choosing Logitech.


Sincerely,

Susan

I have a logitech cordless mouse. We have just replaced the batteries in both the mouse and printer. However the icon is now frozen on the screen. How do we get the mouse keyboard and computer to speak to...


You need to pair the mouse and keyboard with the receiver again.

If I recall correctly, for Logitech the procedure is to press the "connect" button on the receiver, then press a similar button on the keyboard bottom, and then on the mouse. The manual should state the exact sequence. If you have trouble, search online for a manual for your wireless desktop set.
Good luck!

Problem with LOGITECH S 510 cordless keyboard and mouse..


Hello,

I have this same keyboard/mouse set and love/hate it when the batteries die. After you change the batteies, power on your pc, press & hold the connect button on the bottem of the keyboard first and then the connect button on the transmitter. Release them and wait for a few seconds. Repeat the same steps for the mouse.

When I have connection issue with this keyboard after new batteries, I have found most of the time the problem is the connection to the pc and/or batteries in wrong. Good Luck

Logitech wireless keyboard and mouse (ex 100) won't connect


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

Logitech Wireless mouse.


As a rule the mouse is matched to the keyboard and a new mouse probably wouldn't work with the receiver.
Try this:
Normal 0 Turn the mouse over and find the small rest/connect button on the bottom of the mouse and press it. This should connect the mouse to the receiver and work properly. If not, try pressing the receiver button and then press the button on the mouse. This should be done whenever you change batteries or glitch.
Hope this helps you. Bud

You probably already done this but try pressing the receiver button and while it is flashing turn the board over and press the small reset/connect button on the bottom of the board and also the reset/connect button on the bottom of the mouse. It should work okay after that. here is hoping that helps. Bud

Cordless mouse


Hi Does it have replacement batters if so take them out and replace them with new rechargeable batteries if not check that the connections that the dock use are OK failing all that i would sagest that you replace your hardware with new and get the hard ware that you can change the batteries as this may give it a longer life span Hope this works Paddy
