Introduction of the BIOS 3-25
HDD Power Down:
If the system has not accessed data on the hard disk drive during the specified time period,
the engine of the HDD will stop in order to save electricity. You can set 1 to 15 minutes or
select Disable according to your use of the HDD.
Throttle Duty Cycle:
This is used to specify the CPU speed in power saving mode. Six options are available:
12.5%, 25.0%, 37.5%, 50.0%, 62.5% or 75.0% .
Power Button Override:
It is activated when the user presses the power button for more then four seconds while the
system is in the working state, then the system will transition to the soft-off (Power off by
software). This is called the power button over-ride.
Resume by LAN:
To enable this feature, you must make sure your network software and network adapter
(LAN card) support such a function. This function is also called " Wake on LAN " (WOL).
Power on by Ring:
If you connect an external modem to the onboard serial port, the system will be turned on
when a telephone ring-up occurs.
Power on by Alarm:
The RTC alarm can turn on the system. You can set date (of month) and time (hour, minute,
and second).
PM Timer Events:
When one of the specified events occur, the count down made for entry in power saving
mode goes back to zero. Since the computer will enter a power saving mode only after an
inactivity delay specified (time specific for Doze, Standby and Suspend modes) and after it
has no activity, during this time period, any event will cause the computer to re-count the
time elapsed. Resume events are operations or signals that cause the computer to resume
time counting.
