Logitech MX Master 3 Repair

The Logitech MX Master 3 was released in October 2019, featuring a rechargeable battery, an adjustable scroll wheel, and a comfortable thumb rest. It replaced 2017's MX Master 2S, sporting a new design.

There are two application-specific versions of the MX Master 3: the MX Master 3 for Mac and the MX Master 3 for Business.

The model and part numbers can be found printed sideways on a large sticker on the mouse's underside. The device's serial number is also listed here, labeled "S/N."

Some users have reported that the Logitech MX Master 3 has some slight lag when used wirelessly. This is most likely due to the high resolution of the mouse.

If you're experiencing lag, try using the mouse in wired mode or reducing the resolution.

Some users have reported that the scroll wheel on the Logitech MX Master 3 is either too stiff or too loose.

If you're experiencing this, try adjusting the scroll wheel sensitivity in the Logitech Options software.

If your Logitech MX Master 3 is just generally not working, make sure that the batteries are charged and that the Logitech Options software is installed and up to date.
