Have Logitech cordless mouse and keyboard. Number on the bottom of receiver M/N C-B017. I took the screws out of the mouse to fix the terminal for the battery which fell back into the unit. It disasembled with two springs the wheel and housing. Need schematics to put back together. Thanks. George

you should hold the reset button on the receiver for 5 seconds. let it go and immediately press the reset button on the mouse once. If done in this order it should be ok.

Hi, after experimenting a little i have fixed my problem and I think I might be able to help you.

First, try press the connect button on the receiver.. Hold it for 20 sec (might not be necessary).

Then, press the connect button on the mouse and hold it for 20 sec (is necessary)

Next, wait 20 sec (is necessary) then press the connect button on the receiver but do not hold

Finally, press and hold the keyboard button for 20 sec.

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
