Wireless keyboard and optical mouse

I just had the same problem. First of all, make sure the transmitter to the wireless keyboard and mouse is plugged in tightly to the computer. It's possible that you could have pulled on the wire without realizing it, and it's not plugged in tightly! Unplug and replug the transmitter anyway after you change the batteries for the wireless keyboard. Then, there's a button on the transmitter, press it for 3 seconds, then quickly press the small button on the keyboard for 3 seconds, (my small buttons are underneath my wireless keyboard and mouse, and I use the tip of a ball point pen to press them). Then do the same for the wireless mouse. This syncronizes and boots them to start.
I'm not sure about the driver, but try the above first, it worked for me after I changed the batteries on my wireless keyboard and mouse.

Hi
After you changed the batteries did you resync the mouse and keyboard with the receiver?

Hi,

1. Change batteries
2. Go to control panel
3. Click Bluetooth Icon
4. Delete the Bluetooth Mouse
5. Click on Add new wireless device
6. Press the pairing device on the keyboard
7. Bluetooth Mouse will be detected
8. Follow the onscreen instructions

Hope this helps, Tried it several times and it works perfectly

have u changed the batteries on the keyboard?

may be wireless keyboard and mouse was damaged. If not in used, remove the battery inside to avoid damage.

Battery compartment on the bottom of the mouse and beneath the keyboard.

Your batteries could be getting low or your reciever could be too far away.

After changing the batteries and cleaning the corrosion out of the battery case, I pressed the connect button on the Logitech receiver, then the red restart button on the underside of the keyboard and it was fixed!

how do i get the battery out of my mouse .

The battery is under the top side of the mouse; use the tip of your fingernail to lift it up, pop it off gently; then you will see the battery inside.
