I have a Logitech MX Air mouse. It still works perfectly but the rechargeable battery has pretty much worn out and is not holding a charge. I purchased a new battery for it, but can’t figure out how to open the mouse to replace the battery. There are two screws underneath the mouse, near the top, but removing them didn’t seem to do anything and I don’t want to force it and end up breaking the mouse. Can anyone offer a little advice on how to open the mouse? Any help would be greatly appreciated. Thank you!
Once the 4 first screw are remove, use some plastic lever to open a bit inbetween silver and black parts. There is 4 other black screw on the black plastic inside ( behind the silver back) Then you have to gently slide the top of the mouse to the rear. Then you can serarate the top a bit and access to the battery.
