Latch Adjustment
Overview
To secure the display to the top case, the MacBook Pro uses a latch assembly that consists of two
parts—a latch mechanism under the top case (actually attached to the bottom case frame) and
two swinging latch hooks inside the display assembly clamshell. As the unit is closed, magnets
inside the latch mechanism pull the metal latch hooks down into the bottom case, and an
overhang on the latch mechanism clasps the hooks to the frame.
If the display does not properly latch to the top case, fails to remain closed, or pops up without
the display release button being pushed, you can make adjustments to the latch hooks that may
correct the issue. Alternately, you can send the computer to an Apple Repair Center for service.

adjustments to these hooks must be very slight to stay within the slot on the top case.
Before performing the latch adjustment, test the current operation of the latches:
Push the display down to about two inches from the top case. Then push the display very
