4.3.4.4 Stand by Time Out (Minute)
This option specifies the length of the period of system inactivity while the computer is in
Full-On power state before the computer is placed in Standby mode. When this length of
time expires, the computer enters Standby Timeout state. In Standby mode, some power
use is curtailed.
4.3.4.5 Suspend Time Out (Minute)
This option is the same as Stand by Time out function. These two features will be
enabled to monitor power of sub-items “Display Activity”, “Serial port”, “Parallel Port”,
“Floppy”, “Pri-HDD”, and “Sec-HDD” independently. It is also used to control CPU throttle
running function. All of sub-items will be ineffective in selection of disabling “Stand by
Time out” or “Suspend Time out” even if it can be choused by user in BIOS setup menu.
4.3.4.6 Throttle Slow Clock Ratio
This option specifies the speed at which the system clock runs in power saving modes.
The settings are expressed as duty cycle of the STPCLK# signal. This duty cycle indicates
the percentage of time the STPCLK# signal is asserted while in the throttle mode.
4.3.4.7 System Thermal
Set this option to Monitor for CPU thermal monitoring and speed down control. The
system will automatically supervise the CPU environmental temperature. If the CPU
surface temperature reaches the trip point set in Hardware Monitor Setup, the thermal
detection will be effective and CPU will run in throttle control manner. The overall system
performance will be reduced to half. This option is a trade-off of system performance and
stability and configurable by user. The default setting is Ignore. You can choose Monitor
setting to enable this thermal function.
4.3.4.8 Thermal Slow Clock Ratio
This option specifies the speed at which the system clock runs in thermal trip point. The
settings are expressed as duty cycle of the STPCLK# signal. This duty cycle indicates the
percentage of time the STPCLK# signal is asserted while in the over heat mode.
4.3.4.9 CPU Critical Temperature
Set this option to monitor CPU thermal trip point defined by user. If the System Thermal
option in CMOS setup is set to “Monitor” state and CPU surface temperature is over this
critical temperature, the system will automatically enter speed down mode.
