CHAPTER THREE - PL3000 BASICS
45
You can recognize the suspended state by the blank screen and that the
device does not react, with the exception of the power button, to any key press by
turning on the screen. Only pressing the power button gets the device leaving this
state besides a quick flick of the wrist, if the tilt switch is used as a power trigger on
the device. When your device wakes from the suspended state, the Windows CE
resumes. In other words, your device does not reboot the Windows CE when
powered on.
Be aware that when the device is on AC power you cannot power down it, that
is, place it in the suspended state.
When you are interactively using your PL3000, the
device is in the ‘On’ state. If your PL3000 is in some
other power state than the ‘On’, the PM changes the
system to the ‘On’ state when you start operating it, for example, by powering it up,
if suspended. You can recognize the ‘On’ state of the device by the turned-on
screen and its backlight with the adjusted, maximum brightness.
The device leaves this state if you power down it, or if a UserIdle inactivity
timer expires. If the timer expires, the system changes to the UserIdle power state.
Having said that, there is a settings value of Never (a ‘User Idle Timeout’ value).
When you put that setting into effect the timer does not expire but the device
remains in the ‘On’ state until you power down it using the power button.
The ‘UserIdle’ is a transitional power-saving state.
The point to enter this state is nothing but power
saving. In this power state the device gives impression
that it is still powered. Typically, you notice the change to the ‘UserIdle’ state when
the backlights of the screen and the keypad are turned off, but the display remains
on.
Tapping the screen, or pressing any key you can get the device entering the
‘On’ state again. Otherwise after the specified timeout the device enters the
‘SystemIdle’ state. However, as you may expect, there is a ‘Never’ timeout setting
of a SystemIdle timer that disables transition to the lower power-saving state.
The SystemIdle is an intermediate power state like
the UserIdle. Changing to this state requires that a
SystemIdle timer expires. The System Idle timer has a
settings value of ‘Never’ (a ‘System Idle Timeout’ value), if set, the device does not
shift to ‘SystemIdle’ state but remains in the ‘UserIdle’ state until you operate the
device.
It may well be that it is not easy to make difference between the ‘SystemIdle’
state and the ‘Suspend’ state because those power states resemble each other on
the outside of the device. When your device looks as if it were turned off, the best
way to set it to ‘On’ state is to press the power button. If the shutdown dialog
window appears on the display after your device is fully powered, repress the
power button to close the window. Appearing of the shutdown dialog indicates that
the power state was the ‘SystemIdle’.
