This guide covers the replacement of a motherboard in an SGIN X15S. The motherboard connects all the components of the computer together and allows for them to interact with each other. A bad motherboard would result in the computer failing to turn on, boot up, or perform essential tasks. While working on your device, if you notice that the battery is swollen, stop your replacement and follow the swollen battery disposal guide. Before working on your device, ensure that it is turned off and completely unplugged from any power sources.
