My MX 700 mouse stopped working today. I pressed connect a couple times. The mouse is in the base and the red light just keeps flashing. I tried changing the batteries, although admittedly they were not rechargeable, so I put the rechargeables back in. I figure they can't be dead if the light keeps flashing. I unplugged everything, rebooted and plugged it back in, my computer recognized the new hardware but still the mouse won't work - it's too busy flashing that damn red light. Please help.
Now what you have to do is look for a reset button on your mouse and your wireless mouse signal receiver. When the receiver and mouse both are on press the reset button on both of them one by one. This should solve the problem.

I had the same problem, brand new battery, the indicator light still blinking red. I finally got mad enough to shake the mouse kinda hard, and it worked. I then removed and replaced the old batteries in, it started blinking red again, but it worked after I gave it a couple of hard side by side shake. I do notice that there's something moving inside the mouse. It could be a connector that got loose. Hope this fixes your problem
This is from the manual for the Logitech MX700 cordless optical mouse.
1. Press connect button on Base Station.
Its LED blinks green. 2. Press connect
button on mouse bottom. Base Station LED
turns solid green, and then off.
The red laser light stopped working on mine and it turned out to be the connetion between the battery tray and the circuit board. There is a metal tab on the circuit board and a matching one on the battery tray. When the battery tray slides in correctly the two tabs touch and viola (!), my red laser light came back on. Maybe one tab or the other got bent when I slammed the tray in crooked when replacing a battery- who knows.
Look for a small button that protrudes where the receiver is placed at the bottom of mouse.
There are two possibilities for turning on the red light, one is that said button is stuck,if that is the case push it down a couple of times and see if the red light goes on, the other is that the button is broken at it's base.
Also check that battery contacts are clean and hold it firmly.
If you know that the battery is good then try this next.
There is a VERY tiny shark-fin shaped spring-loaded button on the bottom of the mouse that is pressed in, when you insert the receiver, while the mouse is not in use, that turns off the mouse to save the batteries. If you haven't used the mouse in a while, it can get stuck in the in position, so that when you pull out the receiver, it doesn't spring out and turn the mouse on (indicated by the red light on the bottom). If you notice that the light isn't coming on. Just try manually pushing in the little shark-fin thing a couple times to make it spring back out. After a couple times, you should be able to get it unstuck and the red light should come on.
Two things: 1) This mouse and charger does not like rechargeables larger than 1800mAH. The light on the front will(sometimes) go red if you use a higher rated battery than the 1800mAH. You said you replaced the batteries, but might want to check their rating. 2) My mouse gets harder and harder to get a good connection when putting it in the cradle. Might be the contacts are getting dirty. When you put it in the charger, you should see the optical beam (red on the back) go out and the green light on the front turn on. If this doesn't happen, it isn't connected.
You do have the cradle plugged in and the batteries installed the right direction in the mouse? I know it's obvious, but the questions always have to be asked.
The small notch in usb device socket under the mouse was malfunctioning. If you press this notch you will find the mouse red light blink. If you further try pressing this notch at some point the mouse red light comes on constantly. Thats it, hold it there and try to connect first by pressing the usb device connect switch and then the mouse connect switch. The moment the connection is made the usb device stops blinking and the red light on the mouse starts blinking. Wow, it works now. Some one might just open the mouse and fix this microswtich for a permanent solution.
