Suspend; Suspend Primary Wake Up Events - Honeywell MX9 Reference Manual

Suspend

The Suspend mode is entered when (1) the unit is inactive for a predetermined period of time, (2) the user taps the Power key,
or (3) Start > Suspend is chosen. Inactivity means that no devices are causing interrupts to reset the power state.
The Suspend timer is set using Start > Settings > Control Panel > Power Properties > Schemes tab.
By default, any of the primary events listed below will wake the unit and reset the User Idle, System Idle, and Suspend timers.
Wake up events are all configurable via a Power Management API call.
When the unit wakes up, the User Idle, System Idle and the Suspend timers begin the countdown again. When any one of the
above events occurs prior to the Suspend timer expiring, the timer starts the countdown again.
The first wakeup key press or touch is not sent to the operating system or running application. The first key press or touch is
only used to wake up the unit and reset the timers. Once the unit has transitioned from the Suspend mode to the On mode, the
unit, keyboard and touch screen function normally.
The transition to the Suspend power state occurs during the following events:
Timeout of the User Idle, System Idle and Suspend inactivity timers.
l
The Power key on the target device is pressed.
l
An application program calls the Suspend function.
l
The MX9 will only resume from a suspended state if an interrupt occurs and the CPU has been programmed to wake when an
interrupt occurs. An interrupt from any listed device transitions the OS back to the On state.

separate power supply)
External power applied
