ReadyBoard 620
♦
To exit this sleep state, typically the Power On switch is used to wake up the ReadyBoard 620 to
restore full operation, including the Power On LED. Typically, pressing the Power On switch for
less than 4 seconds (default) will restore full operation.
•
3rd state is a hibernate or suspend-to-disk state (S4).
In this state there are no internal operations taking place except for the Power On LED and the internal
RTC. This includes no activity for the CPU, CD-ROM, or hard disk drives. The ReadyBoard 620
appears to be off, except for the Power On LED. Your system will take longer to wake up from this
sleep state, however, since your data is saved to the disk, it is more secure and should not be lost in the
event of a power failure.
♦
To enter a hibernate or suspend-to-disk state, the ReadyBoard 620 must be fully powered on and
the OS transitions the ReadyBoard 620 into this sleep state (S4) under user control.
♦
To exit this sleep state, typically pressing the Power On switch for less than 4 seconds (default) will
restore full operation.
•
4th state is the normal power off or shutdown (S5).
All activity stops except the Power On LED and the internal RTC clock, unless the power cord is
removed from the AC power source.
♦
To go to a fully powered down state, the ReadyBoard 620 must either be powered on, or in a sleep
state, and then the Power On switch is pressed for 4-to-6 seconds.
♦
To go to a fully powered up state, press the Power On switch for less than 4 seconds (default) and
full operation is restored.
The OS may provide additional programming features to change the activation time for each state, and to
shutdown or transition the ReadyBoard 620 at certain times, which depends on how the OS interface is
programmed. Refer to the OS vendor’s documentation for power management under the ACPI standard.
Wake-Up Activities
can be used to wake up the ReadyBoard 620 from any of the states
mentioned.
NOTE
Some operating systems use the keyboard, mouse, and Wake-on-LAN (Ethernet port)
as an activity to wake up the system from a sleep state. Refer to
for the
conditions the ReadyBoard 620 currently supports for wake-up activity.
Table 3-17. Wake-Up Activities and Conditions
Signal/Device
Condition
Power On Switch
If the Power On switch is pressed for more than 4-to-6 seconds, the system
will wake up from any of the sleep states.
LAN Ports (2)
If Resume On LAN is [Enabled], then the system will wake from one of the
sleep states through direct addressing, magic packets, or link status changes.
PS/2 Keyboard &
Mouse
If you use a PS/2 keyboard or mouse, any activity from the keyboard or mouse
could wake the system.
USB
If you use a USB keyboard or mouse instead of a PS/2 device, the USB device
could wake the system.
