MacBook Air 13" Mid 2013 Battery Disconnection

Introducción

Internal Prerequisite. Disconnecting the battery.

To ensure that everything is de-energized and won't turn on while you're working, it is recommended that you disconnect the battery.
Grab the clear plastic pull tab attached to the battery connector and pull it parallel to the board toward the front edge of the Air.
Do not lift upward on the connector as you disconnect it or you risk damage to the connector socket.
