    • Carefully lift the battery connector board up off the logic board.

    • It is recommended to bend the battery cables just slightly, to keep the board suspended up above the logic board and out of the way.

    • Do not fold the board completely over, or crease the cables, as this may damage the battery.

    • 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.
