You always want to turn the wireless mouse off before you replace the batteries. The top rated laptop computers use Bluetooth technology to connect to the mouse, and it can become confused if the batteries are suddenly taken away. It will think that the mouse is still connected to the computer even though it is not. You will then have to restart the computer to reset it. If you turn the mouse off, you can avoid this problem.
