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.

  1. Remove 7 6mm  Phillips #0 screws from bottom of laptop.
    • Remove 7 6mm Phillips #0 screws from bottom of laptop.

    • Pull bottom off of laptop using tab.

  2. Remove 1 4mm Phillips #0 and 1 10mm Phillips #0 screw, unplug yellow, black, and red cable, then remove fan.
    • Remove 1 4mm Phillips #0 and 1 10mm Phillips #0 screw, unplug yellow, black, and red cable, then remove fan.

    • Repeat for other fan.

    • 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 SATA cable and remove hard drive.

    • Make sure to pull cable straight out in order to ensure it stays intact.

    • Remove 2 6mm Phillips #0 screws and remove SSD.

    • Make sure you pull SSD straight out so it doesn't get damaged.

    • Unplug both red and black speaker cables. Pull straight out so the connectors aren't damaged.

    • Unplug battery cable.

    • Pull straight up so as not to damage pins.

    • Remove 13 5mm Phillips #0 screws and remove inner case.

    • Case may take some force to remove, but don't apply excessive force or you risk breaking the plastic connector tabs.

    • Use card or other flat object to remove battery from housing.

    • Be extremely careful removing the battery. If punctured, hazardous chemicals can be released, or the battery could catch fire or even explode.

    • replace 11.1v, 7500mah Li-ion battery, MSI part number: BTY-L77, with equivalent battery, and bind to case with adhesive.

Conclusion

To reassemble your device, follow these instructions in reverse order.

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).
