Introduction

If your Razer Basilisk V3 gaming mouse is no longer responding, showing connection issues, or has suffered liquid or electrical damage, the motherboard may need to be replaced. This guide will walk you through removing and replacing the internal motherboard so you can bring your mouse back to working as intended.

Before starting, unplug the mouse and work on a clean, static-free surface. This repair requires patience and careful handling of small connectors, as well as identifying and detaching ribbon cables without tearing them. Try to get comfortable using precision screwdrivers and prying tools to avoid damaging any components.

Why perform this repair:

The mouse does not power on or connect via USB
There is physical damage/burnt components on the motherboard

Warnings:

Always discharge static before touching internal components
Be careful when prying clips as they can break easily

Heat the skate using a heat gun or hair dryer.
Using the pointy end of the spudger pry away a corner of the skate.
If the adhesive does not pull away easily, heat the skate more.
Once the corner of the skate comes free use the flat end of the spudger to peel off the rest of the skate.
Repeat these steps for each of the skates.

Carefully pry apart the mouse's top and bottom halves. Using the iFixit opening tool, start at one corner and work around the edge.
Be cautious of the clips that may break during this process.
Using a plastic opening tool, gently pry the connector apart by moving side to side to avoid bending the pins.
When reassembling, be mindful that the connector only fits one way, as shown in the pictures.
