Apple PowerBook G3 - Manual (Page 130)

10 Lift the keyboard out of its enclosure and place it on the clean, dry cloth covering
the display.
Again, be very careful not to lift the keyboard too far out of its enclosure so
that you don’t pull the keyboard cable out of its socket.
Don’t turn the keyboard over; just slide it up on the cloth.
Gently move the keyboard up and place it on the cloth
