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.

Insert the blue plastic opening tool into the space between the lower case and the chassis.
-
Slide the opening tool around the perimeter of the case to release the clips holding the case and the chassis together.

Remove the back case.
I found a tough spudger (or even better a plectrum) is best here as the clips, although easy to separate, hold the case firmly leaving a tight gap which a soft spudger may fail to enter.
Hi Benjamin, thanks for the tip!
You also have to pry the near the battery. I experienced that you can't pry the front side.
I used a credit card to pry the clips loose, it worked great. Added 2nd RAM stick easily.

Use a Phillips #1 screwdriver to remove the two 4.6 mm screws that secure the internal battery to the frame.

Lift the battery straight out of its recess and remove it.
DO NOT wedge out the battery - T480 has two screws that hold down a plastic battery tray which easily lifts out after the two frame screws are removed. Wedging out will ruin the battery and could damage the cell and cause a fire.
The guide says to remove those two screws. They are "lifting" with the wedge. Probably more of a way to promote their tools than out of necessity, but idk
