keyboard lock connector (or separate keyboard lock and Power LED
connectors). The computer chassis may not include the keyboard lock and
Power LED on a single connector. The keyboard lock allows the user to lock
the keyboard, protecting the system from unauthorized use. Pin 1 on the
motherboard is identified by the broad arrow.
