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: The left button is stuck on something inside the mouse

Wed, 28 Jun 2023 15:39:35 -0700

The left mouse button was lifted up by accident. I pushed it back down, but now it seems to be caught on something inside the mouse. The button is raised and takes more effort and travels more to make a successful click.

Logitech MX Master: My battery is wonky, running out of charge randomly

Mon, 30 Jan 2023 14:59:49 -0700

My battery is wonky, running out of charge randomly and then if i turn it on and back off it will suddenly be back to 1, 2 or 3 green dots. This can happen mere minutes after charging it. It won't really charge properly either, it the three LED's all light up without the "pulsating 1-2-3" animation when plugged in.

Logitech MX Master: Spilled lemonade on mouse (broken motherboard)

Tue, 24 Mar 2020 09:20:47 -0700

Hey! I spilled 2 years ago a lemonade on my MX Master. I put it away and forgot about it. And since we all have plenty of time home (I guess) I found it and I am trying to repair.

I think there is problem in the motherboard, the mouse won't charge and won't turn on at all.

Usually when I repair pc, laptop, macbook whatever I find spare parts and replace but in the mouse it's not possible (I can not find any spare parts available).

I think here is problem, the contact is rusted.

I am no eletrician I have never done this micro soldering stuff, I don't know how to find the parts needed I am not sure what equipment do I need (surely macro camera) and, here comes the question I don't know whether I should give it a shot and try to learn micro soldering?

Do you think is repairable, should I try it? If so, any advice, litarature to read, tips, tricks, equipment? I mean I have several broken parts, like macbook motherboards, pc motherboard, gpus etc.

I will be glad for any response, I am kind of bored home so I could learn a thing or two.

Regards,
