Introduction
This guide will help you remove and replace the side buttons (often labeled M4 and M5) on your Alienware Pro Wireless Gaming Mouse (Model: PRO-MS and PRO-M-D).
The side buttons are the physical pieces your fingers press. They are essential as they function as Forward (front button) and Backward (rear button) in web browsers, but are mainly used for in-game commands.
This repair may be needed if the plastic buttons are cracked, snapped off, or keep popping out because their tiny internal clip is broken. If your buttons are "mushy" or "double-clicking," the problem is the switch underneath.
Before you begin, power off the mouse and disconnect it from any charger or device.
When you reassemble the mouse, make sure the ribbon line is facing the correct direction.
