Logitech MX Master Series Mouse: Copper contact pads ripped

Wed, 24 Jun 2026 02:35:48 -0700

Hi All. My very first post here. Hope to get some advice from the community here.

I received an MX Master 3S that could not power up. I disassembled it and realized that the 10UH 100 power inductor is gone, and the contact pad highlighted in red was ripped off. I will try to take a close-up photo of it when I get home in a few days.

I have attempted soldering contact pads on bigger boards, but trying it on a mouse would be a first for me. I wonder if anyone here has experience in repairing such problems. Any advice would be appreciated.

Logitech MX Master 3: Middle click randomly not working and some time it would double click.

Mon, 16 Jun 2025 15:07:31 -0700

The mousewheel click would randomly not work unless I pressed it harder than normally. I also noticed that if mashed the button repeatedly it would work normally as if the mashing was priming/warming it up to work normally.

Logitech MX Master 3: MX Master 3 not responding randomly

Mon, 03 Mar 2025 02:53:08 -0700

I have my MX Master 3 for 2 years now. Recently while using it normally it stops responding for few seconds and then goes back to normal. Not responding no buttons and no movement of the cursor is happening.

This is happening regularly lately and don't know the reason and how to solve it.

It is not a battery issue (i think) as the mouse is fully charged.

Logitech MX Master: Not Charging? The 3 lights don't light up.

Fri, 14 Nov 2025 08:29:30 -0700

My MX Master( M-R0052) seems to work fine but the charging lights don't light up when plugged into a known good cord and power source. Is there a way to know if it is still charging other than waiting for the battery to go dead? Which board might be suspect? The Battery is a new battery.

Logitech MX Master 3S: Can't get the ribbon cable in

Mon, 09 Sep 2024 14:34:44 -0700

The lock broke and I can't get the ribbon cable back in. Am I screwed? The cable came out super easy and nothing had broken. Trying to get it back in has been like wrestling an eel. The lock fell off and the ribbon cable won't slot in no matter what I do. I can get the lock back in without the cable and it stays. Can't get the cable in though.

The idea of do it yourself repairs is a nice idea, but nothing stresses me out more than ribbon cables and jst terminals.

Logitech MX Master 2S: Is their a plan to get a scroll wheel replacement available?

Mon, 20 Nov 2023 11:23:22 -0700

One of the most common complaints and "failure" points of this mouse is the rubber like material on the scroll wheel deteriorating. Are their plans to make an official replacement part for this available to extend the life of our mice? Maybe even redesigned like the 3/3s with no rubber?
