There are four strong magnets under the keyboard bezel at the bottom of the frame. These can stay in place during the repair, but you can remove them to avoid losing them.

Lift and remove the keyboard bezel.

During reassembly:

If you removed the magnets, make sure they are installed so they attract the magnets under the display bezel.

Make sure the side of the keyboard bezel with countersunk (conically shaped) screw wells is facing up.
