BIOS Setup Information
Hard Disk Power Down Mode
This option specifies the power management state that the HDD enters after the specified
period of hard drive inactivity. This is similar to the video power control function. If the user
chooses
Standby
or
Suspend
, it will depend on the period specified in the parameters
Standby
Timeout
or
Suspend Timeout
.
Standby Time out (Minutes)
This option specifies the length of time the system is inactive while the computer is in its full-
on power state before the computer is placed in Standby mode. When this time expires, the
computer enters
Standby Timeout
state. In
Standby
mode, some power use is curtailed.
Suspend Timeout (Minutes)
This option is the same as the
Standby Timeout
function. These two features must monitor the
power of sub-items
Display Activity
,
Serial Port
,
Parallel Port
,
Floppy
”,
Pri
-
HDD
, and
Sec-
HDD
independently. It is also used to control the CPU throttle running function. None of the
sub-items will operate when either Stanby Timeout or Suspend Timeout are disabled, even if
they are selected in the BIOS Setup menu.
Throttle Slow Clock Ratio
This option indicates whether the speed at which the system clock runs in system power-saving
modes. The settings are expressed as a duty cycle of the STPCLK# signal. This duty cycle
indicates the percentage of time the STPCLK# signal is asserted in the throttle mode.
Display Activity
This option specifies if the BIOS is set to monitor activity on the display monitor for power
conservation purposes. If it is set to
Monitor
and the computer is in a power saving state, BIOS
watches for video display activity. The computer enters the full-on power state if any activity
occurs. BIOS reloads the
Standby
and
Suspend
timeout timers if activity occurs on the specified
IRQ lines. If set to
Ignore
, video display monitor activity is not monitored.
