Right mouse click is not working

Hello,

my right mouse click suddenly stopped working on my MX Master 2s.

I tried following steps without any success:

1) Turned mouse on/off

2) Connected mouse via bluetooth dongle on other computer

3) Switched left/right mouse click via Windows settings

4) Bought a new original mouse click switch (from Omron) and replaced the old switch

-> After all my right mouse click is not working!

-> I now use a wired, old mouse and I have no problem at all with this.

Can you please help me?
Do you think it might be a hardware malfunction on the motherboard?
I mean I even replaced the switch.

Thanks,
Fabian

Have you checked the top "activator plate", of the mouse that activates the switch uppon depression of the mouse buttons? It sounds like the there may be a gouge in the "activator plate" which prevents the plate from making contact with the switch.

If you do see this I used some hot glue and filled in the gouge on an MX master 3 and its been going strong for a few months now. But you can also use other fillers to get better results.

Hello Zach,

thank for your help. Unfortunately this did not help. The "activator plate" has full contact to the switch. I even demounted the upper shell of the mouse and clicked on the switcc directly with my fingers. The right mouse click gives a nice snappy accoustical feedback, yes, but there is no response on my computer. In my opinion there must be a hardware malfunction on the motherboard.


Well I don't know what to now. Seems to be broken, unrepairable.
