• Grasp the Interposer with tweezers.
• An interposer is the name for an interface that links one electrical connection to another. In this repair, it is the board connecting the battery to logic board.
• Lift the Interposer off the logic board and remove it.
• Removing this board will ensure that the battery remains disconnected throughout your repair, preventing your computer from accidentally powering on. It's also a good idea to take it out so it doesn't fall out unexpectedly.
