Front Panel Connector Set (CN1) A through G
A. Over-ride Power Button Connector
The power button on the ATX chassis can be used
as a normal power switch as well as a device to
activate Advanced Power Management Suspend
mode. This mode is used for saving electricity when
the computer is not in use for long periods of time.
The Soft-OFF by PWR-BTTN function in BIOS's
Power Management Setup menu must be set to
"Delay 4 Sec." to activate this function. (See section
3-4)
When the Soft-OFF by PWR-BTTN function is
enabled, pushing the power button rapidly will
switch the system to Suspend mode. Any occurence
of external activities such as pressing a key on the
keyboard or moving the mouse will bring the system
back to Full-On. Pushing the button while in Full-
On mode for more than 4 seconds will switch the
system completely off. See Over-ride Power Button
Operation diagram.
B. Keyboard Lock & Power Indicator LED
Connector
Plugging this connector into the lock on the front
panel of the system case allows the lock to enable
or disable the keyboard. This function provides
limited security against casual intruders. The
power indicator LED shows the system's power
status. It is important to pay attention to the
correct cables and pin orientation (i.e., not to
reverse the order of these two connectors.)
Blinking LED in Suspend Mode
While in Suspend mode, the LED light on the front panel of your computer will flash.
Suspend mode is entered by pressing the Override Power Button, pushing the Green
button on your ATX case, or enabling the Power Management and Suspend Mode
options in BIOS's Power Management menu. (See section 3-4)
