Turning On/Off Power - NEC ShieldPRO N22A User Manual

2.2 TURNING ON/OFF POWER

This section describes how to turn on or off the power of N22A and power saving features
(including suspend (standby) and pause states).
Take special note on turning off the power. If you turn off the power of N22A improperly, not
only data and programs but also the machine itself may be broken.
Power states
The power states of N22A is divided into four states, or power-off, power-on, suspend (standby)
and pause states. These states are changed as follows:
(1) Power-off
state
or
(4) Pause state
(1) Power-off state
In the power-off state, N22A is not used at all due to shutdown of Windows or another exit
operation.
(2) Power-on state
In the power-on state, N22A is used normally.
(3) Suspend (standby) state
Suspend (standby) is a power saving state where the power to the hard disk drive is shut
off. The power supply of the N22A is not completely shut off. In this state, the working
data is temporarily saved in memory and necessary power is supplied to keep the data in
the memory.
Because working data is saved in memory, N22A can immediately return to the original
state at recovery from the suspend (standby) state.
* Some OSs cannot enter N22A into the suspend (standby) state.
(4) Pause state
When the N22A enters the hibernate state, all data in the memory is saved to the hard disk
and power to the N22A goes off without exiting Windows.
If the power is turned on again, N22A is recovered to the same state as that at the
power-off. Due to the power-off, it takes a longer time for recovery from the pause state
than for recovery from the suspend (standby) state.
* Some OSs cannot enter N22A into the pause state.
See "Indicator lamps" of "Names and Features of Sections of FC-N22A" in "Chapter 1
