an interrupt, the system returns to the Fully On state until all pending instructions are executed. If the Idle Mode option is disabled in the BIOS, the system will not enter Idle mode. Table 7-4 System Activity in Idle and Standby Modes System Activity Idle Mode Standby Mode Stop Grant (STPCLK#) Internal CPU Clock External Clock (CLK) Hard Disk Drive On* Standby (spin down) Display On* Off * Power saving timeouts can be configured independently for these devices allowing them to enter a low-power state while the system is in Idle mode. Note that this table does not depict a precise timing diagram. The illustrations given in this table are intended to show the relative characteristic activity of these signals. Standby Mode 7 Standby mode is entered when the Standby Mode Timeout (configured in the BIOS) occurs. The CPU, supporting chip set, and RAM remain powered, however, the CPU’s internal clock is stopped (stopping the CPU) as indicated in Table 7-4. Any user activity that generates an interrupt will cause a transition out of the Standby state to the Fully On state. The hard disk drive is forced into standby mode (spun down) when the standby mode timeout occurs. Note however, that the hard disk drive can be configured to spin down earlier by setting the HDD Spin-down Timeout BIOS option. The display system (including backlight) is also turned off when the standby timeout occurs. The display can also be configured to turn off earlier by setting the Video Timeout BIOS option. Suspend Modes 7 The system can be configured to use one of two different Suspend modes: Suspend-to-Disk or Suspend-to-RAM. (These two modes are also referred to as “normal” and “save-to-disk” in some related documents.) System power activity in each of these modes is described below. (Refer to Chapter 2 for information on selecting the suspend mode in the BIOS.) Suspend-to-RAM State 7 In the Suspend-to-RAM state, power is maintained to RAM, video memory, and resume circuitry while all other system circuitry and power managed devices are powered off. The PC Card slots will also remain powered if the Resume On Modem Ring option is enable in the BIOS. Pressing the Suspend/ Resume button, or a resume request generated by a modem ring will cause a transition to the Fully On state. The Suspend-to-RAM state is best suited for applications where system operation is suspended frequently and a quick resume time is desired. 7-6 System Power
Suspend-to-Disk State 7 In the Suspend-to-Disk state, data in RAM and video memory are written to the hard disk drive and, with the exception of resume logic circuits—connected to the Suspend/Resume button switch, the system is completely powered down. This suspend state uses the least amount of battery power. Before you configure your system to use the Suspend-to-Disk state, consider the following factors: • More time is required to resume system operation as the hard disk drive must spin up and data must be read from the hard disk drive. • You must first create a save to disk partition or file before you can use the Suspend-to-Disk state. • System operation can only be resumed if the Suspend/Resume button is pressed. If your application uses the resume on modem ring feature, you must configure the Resume On Modem Ring option in BIOS setup. Suspend Events 7 Under typical use, system operation is suspended when the Suspend Timeout expires, the Suspend/ Resume button is pressed, or a suspend request is generated by a software application. A critically low battery will also force the system to suspend operation. Note, however, that this event will force the system into Suspend-to-RAM mode regardless of the Suspend Mode setting in the BIOS. Fully Off State 7 In the Fully Off state, the system is fully powered off. Note however, that some circuits connected to the battery will continue to draw a very small amount of current when the system is off. For this reason, the pen tablet should be stored with a fully charged battery pack if the system will not be in use for more than a few days. Burst Mode 7 In addition to the power management modes mentioned earlier, the Stylistic 1200 pen tablet also functions in “Burst” mode. Burst mode is a short (2 ms) period during which the CPU runs at full speed. Burst mode is entered when the system is in Idle or Standby mode and one of the following burst events occurs: • System management interrupt (SMI#) signal active • IRQs 1 through 15 set • IRQ 0 set (system timer) This event only generates a burst event if Max Battery Life is selected for the Power Savings BIOS option.
