Best answer, don't buy logi any more. I have MX2 and MX3, I suspect the battery is fine in the MX3 as it works for literal weeks on the red light flashing randomly for days at a time, charge it, no difference.
Checking reddit, the popular theory is warranty burnout, so the solution is to stop buying these expensive devices that are on the whole no better than something half the price if you look around, and last exactly until warranty expires before starting to randomly play up, strangely enough.

I have a Master 3S and after a year left click gone and I couldn't find proper switch to replace. Also after opening mouse, red flash light shows up and I don't known what to do. Warranty is ended and my mouse is dead. A well known brand like Logi should be responsible for this kind of malfunctioning.

Hello
It could be:
1) dead battery/batteries
2) driver not installed
3) usb dongle wasn't recognize properly due to glitch
4) drive for dongle wasn't installed correctly or corrupted for usb port its in
5) dongle radio burnt out
6) mouse radio burnt out
7) you forgot to put usb dongle in usb port.
Try fresh batteries
Try plugging the dongle in another usb port
Try unistalling then reinstalling the driver
Try going in device manager, see if there are unloaded drivers and either remove devices then refresh list; or update drivers.

Hi and thanks for your reply the battery is a rechargeable one and is fine I tested with a multimeter , about the dongle and signal the mice is unrecognizable by any other device no matter if is on the channel one two or three other thing to take in consideration is the mice is fully cordless and the usb c port is just only for power
Same problem, LED (red) flashing endlessly. Contacted support to carry out some tests together, probably resulting in a faulty card. They suggest buying a new one as it is currently out of warranty. Thank you Logitech for providing me with an expensive mouse that lasted more than 2 years

Unfortunately no , even in instructables or Reddit I haven't had luck, maybe if I upload more images of each piece separately some one can help us

@antoniocardenas @nahuelpala58349 pictures will definitely help. I would have a look at the USB C port also. especially if the behavior is the same whether it's plugged in or not

I encounter the same problem too. I checked the battery, and it is fine. I don't know what's going on.
