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 Green Override Power Button on
your ATX case, or by enabling the Power Management and Suspend Mode options
in BIOS's Power Management menu. (See section
3.5
)
Poly-fuse Over Current Protection:
The poly-fuse protects the system from dangerous voltages that the system might be
exposed to via keyboards or USB connectors. In case of such an exposure, the
poly-fuse will immediately be disconnected from the circuit just like a normal fuse.
After being disconnected for a certain period of time, the poly-fuse will return to its
normal state. Then the keyboard or USB connector can function properly again.
Unlike conventional fuses, the poly-fuse does not have to be replaced, relieving the
user from such inconveniences.

PWR-SW
(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 is a
power-saving mode when the computer is idle 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.
When the Soft-OFF by PWR-BTTN function is enabled, pressing the power button
rapidly will switch the system to Suspend mode. Any occurrence 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
