30 Thor VM3 with Microsoft Windows Embedded Compact 7 User Guide
System Idle / Display Off Mode (D2)
Backlight and display are off. The status LED is solid green. The Thor VM3 transitions to
this mode from User Idle after the System Idle timeout period has passed without a pri-
mary event occurring.
Suspend mode (D3)
All devices that are not configured as wakeup events are powered off. The status LED is
blinking green if external power is connected and off if external power is not connected.
The Thor VM3 transitions to this mode from System Idle after the Suspend timeout
period has passed without a primary event occurring.
By default power is turned off to the USB port when the Thor VM3 is in Suspend. The
Thor VM3 can be configured to provide power to the USB port in Suspend using the
Options control panel.
Additionally the power button can be used to enter or exit Suspend mode:
• If the Thor VM3 is On, pressing the power button immediately transitions the unit to
Suspend.
• If the Thor VM3 is in Suspend mode, pressing the power button transitions the unit
to On.
Shutdown / Off Mode (D4)
The Thor VM3 shuts down when the Thor VM3 is operating on power and the UPS bat-
tery becomes critically low regardless of the current power management state. The Thor
VM3 remains Off until external power is applied. The Thor VM3 may restart automati-
cally when external power is applied or may require the user to press the Power button
depending on installation and configuration.
The Thor VM3 transitions to Off mode from Suspend after the Shutdown timeout period
has passed without a primary event occurring. If the Thor VM3 has external power
applied or a sufficiently charged UPS battery the Thor VM3 may restart automatically or
may require the user to press the Power button depending on installation and configu-
ration.
A Real Time Clock (RTC) powered by an internal battery maintains the date and time
while the Thor VM3 is off.
