1.16 System Sleep / Resume
When Advanced Power Management (APM) is activated in the system
BIOS and the Operating System's APM/ACPI driver is loaded, Sleep
mode (Suspend) can be entered in one of three ways: press the front
panel power button, select “Suspend” in Windows 95 Start Menu or
no system activity for a pre-defined length of time. To use the power
button to control system sleep/resume, the option “Power-Off by PWR-
BTTN” in the BIOS Power Management Setup has to be set to “Delay
4 Sec.”
When the system enters the sleep mode, the CPU stops running, the
82440LX/EX AGPset and related circuits stay in the lowest power
state, the HDD stops spinning, the monitor screen becomes blank, the
power LED indicator on the front panel dims, and the CPU cooling fan
and secondary fan are turned off (Note: in order to turn off the fan in
sleep mode, you need to connect the CPU cooling fan or Chassis fan
to the on-board fan power connectors marked FAN1 or FAN2).
1.17 Wake On LAN (WOL)
Wake on LAN (WOL) is a 1x3 pin header for remote wake up of the
computer through a network. Wake on LAN requires an PCI add-in
network interface card (NIC) with remote wake up capabilities. The
remote wake up header on the NIC must be connected to the onboard
Wake on LAN header. The NIC monitors network traffic at the MII
interface and when it detects a Magic Packet (MP Wake-up) it asserts
a wake up signal that powers up the computer.
Note:
For WOL (Wake on LAN), the 5Vsb (5V standby) line of the Micro-
ATX power supply must be capable of delivering 5V with 5%
tolerance at 720mA or higher.
1.18 System Manageability (Optional)
The System Management Chip (Winbond W83781D) with software,
allows user to monitor system environment such as system and CPU
fan speed (requires fan with tachometer output), CPU warning
temperature, system temperature and system operating voltages.
