Hello, thanks for the tutorial. My mouse is the same as this model.

From time to time it simply disconnects by itself and after a few seconds, it reconnects. I’ve changed batteries already.

This one problem is very annoying, but it works perfectly and I’d really like to keep using it - so I wish I could fix it to continue using it.

Do you guys know anything I could do to solve this?

Mine disconnects after a few minutes of being idle. I just click the left mouse button once to “wake” it. Moving the mouse around will not wake it. I think this is by design to prevent the radio to the USB dongle from needlessly draining the battery. If this is different from what you are experiencing, then the other thing to do would be to consider whether you have other wireless devices that could be causing interference.

Thank you for this guide. I just used it to inspect the wheel. Mine was causing “up-and-down” scrolling behavior on the screen despite rolling the wheel only down. After using this guide to disassemble and clean the mouse, it is working perfectly again.
