J23 Keyboard Lock
J23 is a 5–pin single–inline berg that is attached via a cable to the
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.
J26 Turbo LED
J26 is a two–pin berg that is attached via a cable to the externally–
mounted bipolar Turbo LED. The LED lights when the motherboard is
running at high speed.
J13 IDE LED
J13 is a two–pin berg that is attached via a cable to the externally–
mounted IDE Activity LED. This LED lights when the IDE drive is
running.
In some IDE drives, you may have to disable the
IDE LED mounted on the drive by changing a
jumper or setting a switch on the IDE drive itself,
before the IDE drive sends a signal to J13.
