ACPI Function
Select Enabled only if your computer's operating system supports ACPI (the Advanced
Configuration and Power Interface) specification. Currently, Windows 98 and Win-
dows2000 support ACPI.
Power Management
There are 4 selections for Power Management, 3 of which have fixed mode :
Disabled (default)
No power management. Disables all four modes.
Min. Power Saving
Minimum power management. Doze Mode = 1 hr.,
Standby Mode = 1 hr., Suspend Mode = 1 hr.,
Max. Power Saving
Maximum power management -- ONLY AVAILABLE FOR SL
CPU's.. Doze Mode = 1 min., Standby Mode = 1 min., Suspend
Mode = 1 min.
User Defined
Allows you to set each mode individually. When not disabled, each
of the ranges are from 1 min. to 1 hr.
Power Management Setup
Video Off Method
This determines the manner in which the monitor is blanked.
V/H SYNC+Blank
cause the system to turn off the vertical and horizontal synchroni-
zation signals and writes blanks to the screen.
Blank Screen
This option only writes blanks to the screen.
DPMS
Initial display power management signaling.HDD Power Down is
always set independently
Video Off In Suspend
Controls what causes the display to be switched off
Suspend -> Off Always On All Mode -> Off
Suspend Type
S1 (POS) Power On suspend
All devices are powered up except for the clock synthesizer. The Host and PCI clocks are
inactive and PIIX4 provides control signals and 32-kHz Suspend Clock (SUSCLK) to allow
for DRAM refresh and to turn off the clock synthesizer. The only power consumed in the
system is due to DRAM Refresh and leakage current of the powered devices. When the
system resumes from POS, PIIX4 can optionally resume without resetting the system, can
reset the processor only, or can reset the entire system. When no reset is performed,
PIIX4 only needs to wait for the clock synthesizer and processor PLLs to lock before the
system is resumed. This takes typically 20 ms.
S3 (STR) Suspend To RAM
Power is removed from most of the system components during STR, except the DRAM.
Power is supplied to Suspend Refresh logic in the Host Controller, and RTC and Suspend
Well logic in PIIX4. PIIX4 provides control signals and 32-kHz Suspend Clock (SUSCLK)
to allow for DRAM refresh and to turn off the clock synthesizer and other power planes.
Modem Use IRQ
Name the interrupt request (IRQ) assigned to the modem (if any) on your system. Activity
of the selected IRQ always awakens the system.
Suspend Mode
When the suspend mode has been enabled after the selected period of system inactivity,
all devices except CPU will be shut down.
