Front Panel Connector Set (CN9) A through E
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.
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.)
Suspend to RAM (STR)
The Suspend to RAM (STR) also known as S3 sleeping state feature allow the system
to go into a low wake-up latency sleeping state where all system context is lost except
system memory. CPU, cache and chip set context are lost in this state; the OS and
drivers must restore all device context. Hardware must maintain memory context and
restore some CPU and L2 configuration context.
