Power Management States
Power Management States
This section introduces the Windows CE power management state
nomenclature used by the WS4 and describes how each state is displayed on
the WS4 Operator LED.
References to Windows CE power management states are specified in bold
capitol letters, e.g., NOPOWER, SUSPEND, etc. See the section on Operating
the WS4 in Chapter 3 for more information on how to enter and exit the
various power states.
UNPLUGGED
• The AC power cord is not connected to a wall outlet. The WS4 will be in
this state when it is started for the first time or if the unit experiences an AC
power failure while operating, but is not connected to a UPS.
• The Operator LED is Off.
NOPOWER
• The AC power cable is attached, but the operating system and applications
are not running. RAM contents are undefined.
• The Operator LED is Off.
ON
• Windows CE and POS application is operating. RAM contents are
maintained.
• The Operator LED is solid Green.
SUSPEND
• Windows CE and POS application is not running,. RAM contents are
maintained. Restoring the unit from SUSPEND restores the LCD screen and
contents of the LCD Customer Display(s), if attached.
• While in the SUSPEND mode, the behavior of individual MICROS POS
Applications may vary. Refer to the POS Application Documentation for
more specific information.
• The Operator LED is solid Amber.
IDLE
• This Windows CE power management state is not supported by the
Workstation 4.
Last Power State Retention
The WS4 retains the current power management state in an on-board
EEPROM. This means if the unit is ON and AC power fails, it returns to ON
when AC power is restored with no action required by the operator.
