Cannot open mouse to insert battery

Install the batteries (2 AA batteries) into the mouse. Locate the red laser light underneath the mouse. Next to the light, there is a small button that will require a small object, such as the end of a pen, to press. Press and hold this light for 3 seconds. You should observe several flashes of red light and then a steady red light when it is ready

I have the same problem and have tried just about everything, still no result

Thank you for using FixYa,

On my Logitech mouse the release button is on the back and you slide it with one hand and pick up on the front panel with your finger nail and it should come open. Not under the scroll bar, but the front of the mouse is where it opens.

I hope this was a help to you and please comment if it resolved your issue.

1. There should be a cover on the bottom with a release lip the batteries are here to replace. this is located right below the on/off button.

Where do I change the batteries for my mouse? I can't find where the batteries go.

This article applies to the following products:
All Logitech cordless mice

For some cordless mice or trackballs, there is a slot for the battery door on the bottom of the mouse. Between the slot and the outside edge of the door is a thin strip of plastic. If you compress this thin strip of plastic towards the slot, the catch on the door will release and the door should open.

On other mice, the battery door is on the top of the mouse. Simply slide the top of the mouse cover down and lift the door up. There should be an etched diagram on the door indicating which direction to slide the door.

Once you have opened the battery door, remove the old batteries and dispose of them according to your local waste disposal regulations. Then insert the new batteries into the battery compartment using the diagram in the compartment as a guide. When you have finished inserting the batteries, replace the battery door.
