The PowerBook 180 has a removable Ni-Cad battery on the side. Before we start this repair, we need to make sure the computer does not have any power source - so you don't get shocked and the computer doesn't die.
Slide the battery door to the front of the computer, as directed by the arrows.
Pull out the battery.
