Using the Stylistic ST4000 Series Tablet PC

This chapter covers the fundamental concepts, basic system operation and use, and system functions of the Stylistic ST4000 Series Tablet PC. You should familiarize yourself with this information before you attempt to operate the system.

P O I N T

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.

SYSTEM STATES

Before you begin using the Stylistic ST4000 Series 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.

P O I N T

The system consumes the same amount of power whether it is in Hibernate (Save-to-Disk) mode or the Off state.

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 Stylistic ST4000 Series 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.
