Introduction
If your Logitech Signature M650 L wireless mouse has a scroll wheel that skips, scrolls inconsistently, or no longer registers movement, this guide will walk you through replacing the scroll wheel assembly.
The scroll wheel assembly is responsible for translating physical wheel movement into scrolling input. When this component wears out or becomes damaged, the mouse may scroll erratically, reverse direction unexpectedly, or stop scrolling altogether.
This guide demonstrates how to disassemble the mouse, remove the existing scroll wheel assembly, and install a replacement.
Before beginning this repair, power off the mouse and remove the battery to avoid accidental input or electrical damage.
