Logitech G305: Unvoluntary double clic and can't hold clics

Fri, 14 Nov 2025 08:10:01 -0700

Hello, after a year and half of normal use, the left button of my G305 logitech mouse will do a constant double clic when I'm trying to do just one clic. Also, when holding down a clic it will deselect the object.

I've tried contacting Logitech and a warranty of Amazon about this, and donde pretty much all the troubleshoting guides they've given me, and the problems still persist.

I think it may need a replacemente of the button, but I don't know how to do it or where could this be done, any help would be appreciated. Thank you in advance.

Logitech G502 Hero: Can't click and drag with my mouse

Mon, 28 Jul 2025 19:28:11 -0700

My G502 Hero mouse either doesn’t register single clicks or it double clicks and almost never lets me drag items on the screen. I’m guessing it’s a hardware button problem, but I’m no sure. Can it be fixed?

Logitech G602: Cursor not moving, but the rest works just fine.

Thu, 18 Aug 2022 16:09:09 -0700

So i have been !#^&@@ off so bad that i smashed my mouse on my mousepad and now it only clicks but it won't move on screen. So i opened it up, and i'm not seeing any noticable damage. Also i don't see any damage particularly close to the optical led light. All the other functions like adjustable dpi and such are working.

When i hover my finger under the sensor, then the led light turns on and when i remove it, the light turns off. So it is registering my movement right? Then what could possibly be broken?

I tried plugging the usb receiver out and in again, the same goes for the usb port of the receiver's extender.

I also switched out both the batteries, but to no avail.

Logitech G703: Why is my mouse buttons not registering a lot of the times

Wed, 18 Jan 2023 01:48:12 -0700

I have a logitech g703 and both left and right clicks have issues, I cannot hold them down without them unholding randomly even tho i kept them held down. This makes it hard to highlight passages in assignments or hold down the fire button on a video game as it keeps releasing randomly.

Logitech G602: Logitech G602 random button commands upon mouse wake up

Tue, 10 Oct 2023 07:50:18 -0700

So for quite a few months I get intermittent issues with my mouse performing a random key press/command upon the mouse waking up.

Sometimes it’s simple like it’ll input the back arrow if I move the mouse after watching a long enough you tube video for it to sleep so it just goes back in the video 5 seconds. But lately I get weirder commands like one that makes my webpage disconnect from the internet, and/or go a page back from where it was while browsing.

Restart sometimes helps and sometimes it just does another strange command instead. like close the current window I’m in…

Any trouble shooting help would be appreciated.

Logitech G602: Screwed up during desoldering?

Tue, 17 Feb 2026 08:02:03 -0700

I'm totally new to soldering and I thought I could give it a try replacing the micro clicker for my G602 Logitech mouse.

I had a very hard time desoldering the old micro clicker out and I kinda messed up.

(I don't really know what a copper pad is), but I think I damaged one while desoldering. Located on the top right of the photo. I'm not sure if I damaged the others as well.

https://pictub.club/image/sytWkn

More pics.

1 removed both micro-clickers. Compared to the one below, the one on top looks blackish and burnt. I'm afraid i burnt the top PCB by putting the tip of the solder iron too long?

https://pictub.club/image/sy5RHZ

The other side of the PCB.

I'm just wondering if there's any way to salvage this PCB ? I'm not putting my hopes high in fixing this mess but I thought perhaps someone could help/guide me. Thanks

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?

Logitech G502 Proteus Core: How are the mousewheel side switches called?

Sun, 02 May 2021 21:00:31 -0700

So the right side button on my mousewheel is pretty much dead, only when I apply strong pressure it will sometimes notice a click but most of the times it doesn't. I want to replace that switch, but I don't know what kind of switch it is so I have no idea where to get one.

Here is a picture of these switches

Can someone help me out?

Logitech G303 SHROUD EDITION: Solder Pads Detached During Removing Micro Switches? (Logitech G303)

Thu, 13 Nov 2025 07:37:58 -0700

First time soldering, i practiced on a few cheap mice and got the hang of desoldering and resoldering the micro switches pretty easily, however for whatever reason the solder simply wouldn't detach from the solder pads on my g303 i spend hours trying and eventually i decided to just try pulling them out little by little with pliers after heating up the remaining solder on the pcb, but it seems to have taken off a few of the solder pads (I believe that's what they're called) with it? Before i try messing with it some more i wanted to ask first what i should do, do i need to try and replace/improvise the solder pads in order to solder on the new switches? Or is there a work around? This is my first time doing this stuff so excuse me if any of my terminology is wrong, i will include some pictures of my pcb below.

Logitech G900 Chaos Spectrum: How to reassemble scroll wheel assembly

I took apart my scroll wheel for cleaning etc, well now when I click the scroll lock button the button gets stuck down, and wheel is not free.

The spring on the right side, I suspect that´s the cause since the one on the right looks fine.

Logitech G305: Mouse sensor seems to have broken

Thu, 30 Oct 2025 04:24:18 -0700

My G305 has been working pretty much perfectly for the past 2-3 years but I went away for a few days and now I've come back and the sensor seems to be dead. The battery is new and the lights on the mouse work and aren't flashing red like they usually do when the battery is low but the infrared sensor light is gone. I really like the mouse and it was pretty expensive for my budget so I don't want to have to replace it bc I wouldn't be able to get another 305 so I wanted to know if there was anything I haven't thought of to fix it before I try taking it apart.
