Remove the single 2.3 mm Phillips screw securing the battery connector to the logic board.

To reduce the risk of a short, you can insert a battery blocker or a modified opening pick to disconnect the battery.

Be very careful when you isolate the battery using a battery blocker. The battery contacts are easily damaged, resulting in irreversible damage.

Slide the battery blocker underneath the battery connector area of the logic board, and leave it in place while you work.

If you are having trouble fitting the battery blocker underneath the logic board, you can try using a playing card to disconnect the battery.
