Standby Mode
After the selected period of system inactivity, the CPU clock stops,
the hard drive enters an idle state, and the L2 cache enters a power-
save mode. All other devices still operate at full speed.
Suspend Mode
After the selected period of system inactivity, the chipset enters a
hardware suspend mode, stopping the CPU clock and possibly
causing other system devices to enter power management modes.
HDD Power Down
After the selected period of drive inactivity, any system IDE
devices compatible with the ATA-2 specification or later power
manage themselves, putting themselves into an idle state after the
specified timeout and then waking themselves up when accessed.
Throttle Duty Cycle
When the system enters Doze mode, the CPU clock runs only part
of the time. You may select the percent of time that the clock runs.
VGA Active Monitor
When Enabled, any video activity restarts the global timer for
Standby mode.
IRQ8 Break [Event From] Suspend
You can select Enabled or Disabled for monitoring of IRQ8 (the
Real Time Clock) so it does not awaken the system from Suspend
mode.
