Mouse will not reconnect with micro usb/commputer after changing batteries

I use Logitech wireless mice and so does my wife. After a battery change you have to reconnect the mouse with the wireless receiver
. First push the button on the receiver, then push the button on the bottom of the mouse. It should connect and you will be ready to go. If this doesn't get the mouse working, you may have to unplug the mouse, then plug it back in the USB port, then reconnect to the receiver. Hope that helps.

You only need to have the receiver plugged in to your USB when you want to use the mouse.
Note: When you plug the receiver back in, you may have to reconnect the mouse by pressing the connect button on the receiver then pressing the connect button on the mouse.

Check for a power button on bottom of mouse. Check the wireless adapter. Assuming it's USB, you can unplug the adapter, wait a few seconds and then reconnect it to the USB port.
Could also check that you didn't invert the battery.

AAs and the end (top where you normally hold it ) just slides back towards the rear. and do the following to reconnect ...(you might as well change the batteries a this time as well)
This is sort of general but it just may help.
Make sure your batteries are in correctly.
Make sure the transmitter dongle is in the USB.
Look on the transmitter, the mouse and keyboard itself (bottom) for a little tiny button that says connect or reconnect. Move the mouse about six inches away from the transmitter and press both the transmitter and the mouse.
That should reestablish the signal twixt the two.(or three KB)

If you have a cell phone or cordless phone nearby it could cause interference. Otherwise reboot and try again. Also you can check for updated drivers at the manufacturers website.

There should be a button on the usb itself.You can try removing it plugging it back in then push that button if still red then you can try changing the batteries.

- try changing the batteries - try reconnecting the mouse to the wireless recieve if u have this option in ur mouse
- try changing the usb ports - restart the computer.

Unplug the USB (or PS/2) plug for a couple of seconds and reconnect them. That worked for me when this happened on my older Logitech keyboard.

See if the mouse has a small reset button. You may have to use a pen or something like it to push and hold the button for a few seconds to reset the mouse. That works for me.

Normal 0 Try disconnecting the Mouse Receiver from the USB port and reinstall the CD software program. When the program asks you to connect the Mouse Receiver to the USB port, do so and it should work.
Hope this helps. Bud
