When replacing the keyboard unit, connect the keyboard connector as shown in the figure,
then replace the keyboard. (The leftmost and rightmost connectors should be unlocked by lifting
the clasps from under them. Unlock the center connector by pulling on the left and right of the clasp.)
Hold down the keyboard connection board when pulling out the
cables, so as not to damage the cables.
NOTE: The orientation of the center lock connector is different (opposite) from the
left and right lock connectors. Unlock this connector from the bottom, as shown in the figure.
