J25 Keyboard Lock J25 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.

J28 Turbo LED  J28 is a 2-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.

J31 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 J31.
