Lenovo ThinkPad T480 Motherboard Replacement

Introduction

The motherboard of a laptop is the component that connects all of the other components together. It is the main PCB or primary printed circuit board that exists in many sizes and configurations depending on the laptop. It could also be considered the backbone of the laptop.

If the motherboard of your Lenovo ThinkPad T480 crashes you may need to replace it. Signs that it needs to be replaced include physical damage, freezing or glitching, the “blue screen of death”, overheating, slowing down, blank screen, and not recognizing hardware.

Prior to beginning this repair, be sure to disable the internal battery, power off the device, and unplug the laptop from any external power source.
