Logitech G600 MMO Gaming MSE: G600 Mouse Buttons don't work correctly anymore

Tue, 17 Feb 2026 08:29:32 -0700

The left button doesn’t work sometimes, but when it does there is a high chance that it ‘clicks’ two times, without me pressing that long or harder than normal

On the other hand the right-click (middle-button) sometimes doesn’t work at all or releases the dragged click for a splitsecond (I tested it in various FPS-Shooters.. scoping is !&&*)

I tried to search for a solution (like opening the mouse and maybe clean it etc.) but I was unable to find a solution that doesn’t break the mouse.

I’ve tried a mouse (not suitable for gaming) if the errors would still occur, but they seemed to be fixed.

How can I repair my mouse?

I am working on my wife's gaming mouse. It is marked as a G600 and I found a page for it. But the P/N and description are slightly different.

1) This version has a braided cloth cover.

2) P/N and S/N are on a tag attached to the cord vice underside of mouse.

3) P/N: 810-002849.

The mouse is not responding to some buttons, and I would like to find a way open it up to test them. I could splice in a new cable, but that is a radical solution which may not fix the issue.
