はじめに

This guide will cover the replacement of the motherboard in the MSI MS-1782 laptop. This part of the laptop is responsible for connecting all the processes of the MSI MS-1782. Check out the troubleshooting page if your laptop is having charging related issues.

When working on the laptop make sure to disconnect the battery first. Also be sure to disconnect all the ribbon cables before removing the motherboard. There are separate daughterboards for various I/O and those have to be disconnected for removal as well. Lastly the display cable is the most fragile so be extra careful with that one.
