C. Green Switch/Green LED Connector
Some ATX cases provide a Green switch which
is used to put the system in Suspend mode. In
Suspend mode, the power supply to the system
is reduced to a trickle, the CPU clock is stopped,
and the CPU core is in it's minimum power state.
The system is woken up whenever the keyboard
or mouse is touched. The system resumes in
different ways as defined by Power Management
Setup screen in BIOS.
D. System Reset Switch Connector
This connector should be connected to the reset
switch on the front panel of the system case. The
reset switch allows you to restart the system
without turning the power off.
E. Speaker Connector
F. IDE Activity LED Connector
The IDE activity LED lights up whenever the
system reads/writes to the IDE devices.
G. Turbo LED Connector
This mainboard does not have a Turbo/De-turbo
speed modes. Even though this function does not
exist, the turbo LED will light when the LED is
connected and turbo button pressed.
Poly-fuse Over Current Protection
The poly-fuse protects the system from dangerous voltages the system might be
exposed to via the keyboard or USB connectors. In case of such 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, after which the keyboard or USB can function properly again. Unlike
conventional fuses, the poly-fuse does not have to be replaced, relieving the user
wasted time and inconvenience.
