Description
This option allows you to select the type (or degree) of power
saving for Doze, Standby, and Suspend modes.
Max Saving: Maximum power savings. Inactivity period is 1min in
each mode.
Min Saving: Minimum power savings. Inactivity period is the
maximum setting in each mode (1h for Doze, Standby and
Suspend).
User Define: Set each mode individually. Select time-out periods
in the PM Timers section (see below).
If Advanced Power Management (APM) is installed on your
system, selecting Yes gives better power savings. This enables
power management control by an external program (generally the
operating system).
Determines the manner in which the monitor is blanked.
V/HSYNC + Blank: System turns off vertical and horizontal
synchronization ports and writes blanks to the video buffer.
DPMS Support: Select this option if your monitor supports the
Display Power Management Signaling (DPMS) standard of the
Video Electronics Standards Association (VESA). Use the
software supplied for your video subsytem to select video power
management values.
Blank Screen: System only writes blanks to the video buffer.
Name the IRQ line assigned to the modem (if any) on your
system. Activity of the selected IRQ always awakens the system.
The following modes are Green PC power saving functions. They
are user-configurable only
Management mode.
When the selected period of system inactivity prior to Doze mode
(1 minute to 1 hour) has elapsed, the CPU clock runs at lower
speed while all other devices still operate at full speed.
After entering Doze mode, when the selected period of system
inactivity prior to Standby mode (1 minute to 1 hour) has elapsed,
the fixed disk drive and the video shut off while all other devices
still operate at full speed.
After entering Standby mode, when the selected period of system
inactivity prior to Suspend mode (1 minute to 1 hour) has elapsed,
all devices except the CPU shut off.
When the selected period of drive inactivity prior to HDD power
down (1 to 15 minutes) has elapsed, the hard disk drive powers
down while all other devices remain active. The HDD power down
mode is only available if the hard drive has this capability.
When this option is enabled, the CPU temperature is monitored.
Whenever the CPU overheats, the CPU slows down to lower the
temperature.
The CPU will be slowed down when it reaches the selected "CPU
Overheat (°C)" temperature or higher.
Full speed will be resumed when the temperature comes down to
the selected "CPU Low Temp. (°C)".
Note: If you update the values for the CPU Low Temp. or CPU
Overheat option, they will only be in effect after the VIPer821
is powered off and powered on again.
