To detach the keyboard assembly, first remove the left brace, shown here.  It's held on with two black screws.

Use a Sharpie^® to mark the alignment.

Next, remove two screws attaching the right brace.  (The left and right braces are identical parts.)

These mounting screws are well hidden, as shown here.  A magnet tipped screwdriver helps reinsert the screws.

Then, remove 13 sheet metal screws from the front brace.

A Sharpie^® stripe makes the brace easy to reorient.

Take off the front brace and set it aside.

Finally, remove six screws holding down the rear of the keyboard assembly.

Three mounting holes on the right of the keyboard are shown circled here.

Three mounting holes on the left of the keyboard are shown circled here.

These six sheet metal screws are shorter than those holding down the left and right braces.

Now simply lift out the keyboard assembly and set it aside.
