Caution
The Field PG P4 supports different operating modes, according to the settings in
the Windows power options. The power options are preset at the factory in such a
way that the device always switches to defined operating modes (On, Standby,
Hibernate, Off).
When changing these settings or updating the device with additional hardware (for
example, USB components) or additional software, the operating modes can be
influenced in such a way that the device can no longer switch to the hibernate or
standby mode. Although the screen is dark, relevant components remain active
and consume power.
Before transporting the Field PG P4 in the carrying case, always shut it down or
set it to hibernate mode. You can recognize these modes when all status LEDs are
switched off after the power supply has been disconnected. By doing this you can
be sure that the device is not switched on during transport and that the battery is
not unintentionally discharged.
Energy Options
You can optimize the energy consumption of your PG using the energy options
while maintaining the PG in operate state.
In Standby mode the screen and the hard disk drive are switched off to relieve the
battery pack. After you switch the PG back to normal mode the desktop is restored
with your last configuration. Since PG memory information is not written to the hard
disk drive, you should save your job before you switch the PG to standby mode.
Information stored in memory is lost in case of a power failure.
Note
Select this mode if you briefly interrupt your work (few hours).
In Hybernate mode the screen and hard disk drive are switched off. All data in
memory is stored to the hard disk drive before the PG is switched off. When you
switch on your PG again, all programs and documents that were opened at the
time of shut-down are restored to the desktop. Hybernate mode relieves the
battery pack even more than Standby mode. However, it requires a longer time to
reactivate the PG from this hybernating state.
Note
Select this setting if you want to interrupt your work over an extended period
(several hours) or over night.
Briefly push the On/Off button to reactivate the PG from Standby or hybernate
mode. In standby mode the system LED flashes, in hybernate mode all displays
are switched off.
