Unvoluntary double clic and can't hold clics

Same problem with me, it started after almost a year of occasional/light use.

After searching for a solution for this issue, I found out that it's probably due to extra static electricity beneath the tiny switch inside, so it's temporarily fixed by blowing inside the gap and towards the switch and by clicking on and holding for 20 seconds or so.

I came here when I found out about this website to look for a permanent solution; changing that little switch, maybe.

You need to buy new switches for the mouse, unsolder the old switches and then solder new one to replace defective one. It's pretty easy if you know how to solder and desolder but could be tedious otherwise. I did it for 2 oy my 305 mouse and upgraded the switches for better quality ones, it's pretty much the only thing that will fail on the 305 since they cheaped out on the quality of the switches for that model.

Hi Luisa,
I also have the same problem with my G305. The timing couldn't be so odd.
I suspect it might be something with the software driver because mine, too, was very lightly used.
I would try to uninstall the GHUB software, and rollback to whatever the on-board/default driver of the G305.

I had the same problem as you. This might sound wild but if you are going to replace the switch anyway you might try to:

0) Open the mouse entirely until you reaches the switches

1) Open de actual switch without desoldering it (you can but its not necessary)

[You can open it using something sharp enough to fit between a plastic tab and the base. You'll need to apply very little force to lift the two tabs on the sides]

2) Now you have two options:

2.1) You can just scrape the copper that makes contact with the switch's terminal

(Some oxide might have form between plates due to humidity)

[Safe and easy, but you will need a very thin sandpaper to fit between plates]

2.2) You have to extract the metal piece, scrape it with a sandpaper/nail sandpaper and place it again. You can also try to bend a bit an specific part, which acts as a spring and is already bent, to increase a bit the strenght needed to click

(Well, a bit risky because if you don't blend it properly, it will lose strenght instad of gaining. Also it is a bit difficult to place back the metal piece, I would recommend you to take some photos of how it was placed at the beginning to take reference)

In my case this worked perfectly, i did it 5 times with 2 different mousses and 4 switches. As you migh be thinking, the first time went horrible, but because i didn't know any of these (I blent wrongly the metal piece making it to loose strenght, once I put everything back, everything worked perfectly despite of the loosen strenght of the click. I could barely rest my hand on the click without activating it .

Also, that extra one (that 5⁰) was a second attempt to solve my first mistake, I did it the better I could and totally recovered the losen strenght on the click

I hope it helps you! Let me know if it worked for you!

(I also reapired my scroll later, which was in fact useless, with a similar technique 😁)
