Introduction

This guide will tell MSI GT72 2QE Dominator Pro users how to replace a defective battery. It is a medium-level process that takes 15-20 minutes to complete.

For your safety, discharge your battery below 25% before disassembling your device. This reduces the risk of a dangerous thermal event if the battery is accidentally damaged during the repair. If your battery is swollen, take appropriate precautions.

    • Use a Phillips screwdriver to remove one 4 mm screw and one 10 mm screw from each fan.

    • The 10mm fan screw won't actually come out, as it is attached with rubber piece to fan. Unscrewing it from the lower case will allow for removal, though.

    • Unplug both fans by gently disconnecting the fan connector from its motherboard socket. If you have trouble, gently wiggle the connector to loosen it.

Thanks for this tutorial!

I used it to replace my GT72 2QD Dominator battery. It’s almost the same (yet, not a piece of cake).
