Try removing the batteries from the mouse and place it in the cradle. If the light lights up or flashes, there can't be a problem with the base station contacts. I have the same problem, but I think the problem is inside the mouse.

I have 2 computers both with mx700 mouse and they have worked great for a few years. All of a sudden, both have stopped charging. The green light blinks to say it is charging when in the cradle but within...

I assume you are using usb socket to charge mouse. The voltage on a USB is 5volts , you may have a problem here. It may not be producing the correct voltage. Or you may have a problem with your cradle. I would suggest you see a repair person and get them to look at the USB voltage and the Mouse cradle..
Hope this helps.

Hi smeker2003,

I have the same mouse and the same problem, it has been getting worse for some time. The reason they do this is the gold foil you see on the contacts corrodes away and eventually looses the ability to conduct enough electricity to charge the unit.

If yours is in the beginning stages of failing, simply cleaning the contacts and repositioning it slightly in the charging base may get it charging for now but it won't last long. Mine started having minor troubles about 1 1/2 years ago and completely stopped charging about 3 months ago.

Good news is they are standard AA rechargable batteries, so you can do what I do and simply swap the batteries with another device like phone or camera and charge them in the other device or buy a small wall charger and use it for rechaging once the unit completely stops.

As for the other comment, MX Revo and similar MX series do not have a "user serviceable" battery and as such there is no easy access to it, first try the above suggestion to clean contacts then, if it doesn't work and you have the skill to disassemble and saulder together new battery cells feel free to pry it open, it's preasure fitted but I would recommend just buying a new one as the cost barely justifies the time and expense of rebuilding it.

Hotkey problems

I had the same problem but finally found a solution hidden in the depths of Logitech. It's quoted below. I had to do it a couple of times before it worked, and it seems that you need to reconnect the mouse at the same time. I didn't the first time and then the keyboard refused to work. (Finger trouble?) :-(


The following is from :-

This article applies to the following products:
Cordless Access Duo
Cordless Acess Duo Optical
Cordless access keyboard
Cordless Elite Duo
Cordless MX Duo
Cordless Navigator Duo

You may be able to reset the keyboard and resolve the problem by clearing the keyboard capacitors. To do this, remove the batteries from the keyboard and type continuously on as many keys as possible for one to two minutes. This action should simulate touch-typing; you should not press and hold only some keys down.
After you clear the capacitors, replace the batteries and synchronize the keyboard using the following procedure:
  1. Make sure the batteries are in correctly. A diagram on the device itself or in the Getting Started Guide should tell you the correct polarity for the batteries.
  2. Press the connect button on the receiver.
  3. Press the connect button on the bottom or right hand edge of the keyboard.
    NOTE: If you are using a Cordless Desktop System, you must do this procedure for both the mouse and the keyboard.
The "Connect" button on the mouse is quite small and usually requires a pencil tip or other small object to push it. Remember, ALL Logitech cordless devices will have a synchronization button. If you have the "Cordless Mouse" with Model Number (M/N) M-RN67, the button will be located in a small hole on the lower portion of the back of the mouse. You will need a paper clip to access the button.
