The “keylock switch” is used to lock the computer’s
keyboard. This disables the keyboard so that unauthorized
persons cannot use it. When this function is in use, you will
need to use the unlock key to activate the keyboard.

connector cable attached to the case to the IDE LED connector on the
mainboard.

PN1 - Standby connector
There is no specific orientation. Most of the present AT cases do not support
this feature so most of you can ignore this instruction. If your case has a cable
for the Standby feature, you should connect this cable to the connector on the
Mainboard.

The “standby connector,” unlike the traditional mechanical
switch, is an electronic way to turn the computer’s power off.
To use this feature, the power supply system must permit a
shutdown power supply (+5VSB), support the electronic
switch feature, and must also be used with connector JS1 on
the mainboard. For example, when using Windows 95,
your computer will automatically shut down after having saved
your work when you exit Windows. You do not need to
use the mechanical switch to turn the computer off.
