Logitech MX700 and other series using rechargable batteries.
As much as I love my Logitech MX700 wireless duo sets, and I have 4 of them, there has always been a persistant problem with the design of the mouse stand/charger.
Over a period of time and use, the contact points in the base and the contact pads on the mouse will show considerable wear.
Corrosion used to be the major problem with these.
Electrolysis will eventually eat away the plating on the contacts or, create small dots of corrosion.
While this was extreme in earlier versions, newer ones seem to have much more resistant plating.
Inspect for a small discolored dot on the plates on the mouse. Using a pencil eraser, scrub them off. Do the same with the pins in the charger base.
Apply a tiny drop of WD40 to your finger and wipe both the contact pads and the pins with your finger.
In most cases, this cures charger contact problems.
Don't forget to pull your rechargable batteries and inspect them and their contacts as well now and then.
The second problem is failure of the pins to make good contact with the plates on the mouse.
Once you reach the point of slamming the mouse down into the base to establish contact, it's time to take more drastic action.
First, make sure there is no dirt or debri in the base preventing the mouse from seating correctly.
Disassemble the mouse charger base.
On the bottom, there are two holes. Look carefully at the lable there and note X cuts on either side. These are screw holes.
Insert a small Phillips head screwdriver and unscrew the two screws.
The two parts of the outer shell will now seperate.
In the top portion, note the two small screws holding the pin assembly in place. Remove this assembly.
The pins are mounted on long metal strips that act as springs.
Over time, and from wear, these get pushed in. They no longer protrude far enough through the holes to let the pins adequately make contact with the pads on the mouse.
Insert the tip of your screwdriver under the bottom bend in the pin plate and raise it up 1/8". Holding it there, with your finger, push down on the bottom end pushing the pin through the hole. This will bend the spring back to maximum depth. Repeat on the other side.
Re-assemble all parts.
You will now find the mouse making perfect contact with the pins and charging as soon as you put it in the base.
