Power Management Functions
Device Standby Mode
TIndependent power management timer for hard disk drive devices 
(0-15 minutes, time step=1 minute). 
THard disk drive goes into Standby mode (for ATA standard interface).
TDisable V-sync to control the VESA DPMS monitor.
TResume method: device activated (Keyboard for DOS, keyboard & mouse for Windows).
TResume recovery time: 3-5 sec.
Global Standby Mode
TGlobal power management timer (2-120 minutes, time step=10 minute).
THard disk drive goes into Standby mode (for ATA standard interface).
TDisable H-sync and V-sync signals to control the VESA DPMS monitor.
TResume recovery time: 7-10 sec.
Suspend Mode
TIndependent power management timer (2-120 minutes, time step=10 minutes) or pushing external 
switch button
TCPU goes into SMM.
TCPU asserts STPCLK# and goes into the Stop Grant State.
TLED on the panel turns amber color.
THard disk drive goes into SLEEP mode (for ATA standard interface).
TDisable H-sync and V-sync signals to control the VESA DPMS monitor.
TReturn to original state by pushing external switch button.
Suspend to RAM
TThe system context is maintained in system memory
TPower is shut to non-critical circuits.
TMemory is retained, and refreshes continually.
TAll clocks shut except RTC.
TReturn to original state by pushing external switch button & “PME” events at ACPI mode.

Most systems are already configured by the manufacturer or the dealer.  There is no need to run 
Setup when starting the computer unless you get a Run Setup message.  
The Setup program loads configuration values into the battery-backed nonvolatile memory called CMOS RAM.  
This memory area is not part of the system RAM.
NOTE: If you repeatedly receive Run Setup messages, the battery may be bad/flat.  In this case, the system 
cannot retain configuration values in CMOS.  
Before you run Setup, make sure that you have saved all open files.  The system reboots immediately after 
you exit Setup.
