Using the Fujitsu Stylistic ST4120P/21P Tablet PC
This chapter covers the fundamental concepts,
basic system operation and use, and system
functions of the Fujitsu Stylistic ST4120P/21P
Tablet PC. You should familiarize yourself with
this information before you attempt to operate
the system.
SYSTEM STATES
Before you begin using the Fujitsu Stylistic
ST4120P/21P Tablet PC, review the different
system states (or modes) that the system can
use. Being familiar with these states will help
you determine whether it is appropriate to turn
on, resume, suspend, hibernate or shut down
the system when you begin or end a session.
System behavior for each system state is
described briefly in the following, with each
system state listed in decreasing order of
power usage:
• On state: The system is running and the
display screen is on.
• Idle state: Some system functions are
regulated or turned off to conserve power.
The display screen may be turned off. The
system returns to the On state when pen
activity or other input is detected.
• Suspend-to-RAM mode (S3): System
operation is suspended. Most system
functions are turned off to conserve power.
Power to memory is on, maintaining data in
programs that were running before system
operation was suspended. The system does
not respond to the pen or other input when in
Suspend-to-RAM mode. Refer to the
“Resuming System Operation” section later
in this chapter for information on returning
the system to the On state.
• Hibernate mode (Save-to-Disk) (S4):
System operation is suspended. All system
functions are turned off to conserve power.
Active data in programs that were running
before suspending system operation is
stored on the hard disk drive. The system
does not respond to the pen or other input.
Refer to the “Resuming System Operation”
section later in this chapter for information
on returning the system to the On state.
• Off state: All system functions are turned off
to conserve power. The system does not
respond to the pen or other input. The
system boots at the next system power-on.
Your system may be configured to enter some
of these states automatically after a period of
inactivity to conserve battery power.
When you use the Fujitsu Stylistic ST4120P/
21P Tablet PC, you can change the current
system state in a number of ways, depending
on the system’s current state. To determine the
current system state, observe the Power icon
in the Status display. Table 2-1 on page 20
gives the different system states represented
by the Power icon and describes how you can
change the system state from the current state.
Prior to using your system, be sure to
fully charge the battery if you plan to
run on battery power. Failure to do so
may result in erratic performance.
The system consumes the same
amount of power whether it is in
Hibernate (Save-to-Disk) mode or the
Off state.
