Lifting from the side nearest the battery, rotate the logic board toward the top of the MacBook Pro.

Using the flat end of a spudger, carefully push the MagSafe 2 connector out of its socket on the bottom of the logic board.

When reinstalling the logic board, check the cables at the marked locations to make sure they don't get pinned underneath the logic board.

Clockwise from top: keyboard, trackpad, battery, right speaker, keyboard backlight, display, microphone, headphone jack, left speaker.
